Gold Ocellatus Shell-Dweller (Neolamprologus ocellatus)

Gold Ocellatus Shell-Dweller: identity and suitability

The Gold Ocellatus Shell-Dweller is a small Lake Tanganyika cichlid whose life is organised around an empty snail shell. The currently accepted scientific name is Neolamprologus ocellatus; Lamprologus ocellatus remains common in aquarium literature, research papers and supplier lists. The word Gold identifies a commercial colour form, not a separate species. Its warm yellow-gold tones, darker markings, fin edging and body proportions can vary between fish and can change with age, condition, lighting and social context.

Small adult size does not make this an ordinary peaceful community fish. Ocellatus is bold, territorial and strongly attached to its chosen shell. It needs a mature aquarium with fine sand, several safe shells, hard alkaline water and enough bottom area to create separate territories. For an aquarist prepared to build the aquarium around those needs, it offers unusually detailed behaviour: digging, shell selection, nest maintenance, threat displays and close-range territorial navigation.

This listing is best treated as a specialist small-cichlid purchase, not as a shortcut for a first uncycled aquarium. Read the footprint, shell, water and group-planning sections before ordering. The Lake Tanganyika cichlid collection is useful when comparing fish with similar alkaline-water requirements.

Care summary at a glance

Care point	Practical guidance	Why it matters
Scientific identity	Neolamprologus ocellatus; also widely published as Lamprologus ocellatus	Both names refer to the same Lake Tanganyika species in this listing.
Adult size	Up to about 5.8 cm total length	Small body, but a defended territory needs more floor area than the fish's length suggests.
Minimum footprint	At least a 60 cm-long species-focused aquarium	FishBase records a 60 cm minimum aquarium length; litres alone do not describe usable territory.
Preferred footprint	75-90 cm or more for several territories or any carefully selected companions	Extra length makes shell spacing, sight breaks and retreat routes more workable.
Practical temperature	24-26°C, stable	FishBase records 23-25°C; the practical band allows normal heater control without chasing daily changes.
pH	8.0-9.0	This is a hard, alkaline Lake Tanganyika species, not a soft-acid-water cichlid.
General hardness	9-19 dGH	Stable mineral content and alkalinity are more important than trying to hit one exact number.
Ammonia and nitrite	0 mg/L	A shell is a refuge, not protection from toxic nitrogen waste.
Substrate	Fine, smooth sand deep enough for digging and partial shell burial	Ocellatus moves sand and modifies the area around its shell.
Shell provision	At least one usable shell per fish plus several suitable spares	Choice reduces competition for the only acceptable refuge and supports natural nest work.
Diet	Complete small cichlid food plus suitably sized frozen or live invertebrate foods	The species is recorded as a microfeeder on invertebrates.
Temperament	Territorial around shells; confident despite its size	Group size and tank mates must be planned around territories, not the label "dwarf".
Difficulty	Moderate	Stable Tanganyika water, shell architecture and social observation require preparation.

Scientific name: Neolamprologus or Lamprologus?

Eschmeyer's Catalog of Fishes lists the current status as Neolamprologus ocellatus (Steindachner, 1909). The same catalogue also records valid published use as Lamprologus ocellatus and as quoted 'Lamprologus' ocellatus. That history explains why searches, books, scientific articles and aquarium shops do not all use the same genus.

For identification, the important part is ocellatus and the Lake Tanganyika shell-dwelling biology. This page uses the accepted name in structured fields while retaining the familiar name where it helps a reader connect older care information with the same species. It does not imply that the Gold form is a newly described species or a guaranteed wild locality.

Name seen	How it is used here
Neolamprologus ocellatus	Current accepted scientific anchor.
Lamprologus ocellatus	Established literature and aquarium-trade usage for the same fish.
Ocellatus Shell-Dweller	Clear common name describing the species and its shell-centred behaviour.
Gold Ocellatus	Commercial colour-form description; appearance still varies by individual.

What the Gold form should and should not promise

Gold Ocellatus are selected and traded for a warmer body colour than the more neutral form, but "Gold" is not a colour chart. A dispatched fish may be pale yellow, honey, ochre or more muted when young or newly transported. Darker stress bars, reflective spots, fin trim and eye-ring intensity can also alter the overall impression. A settled fish under appropriate lighting may not look identical to a newly arrived fish or to a representative photograph.

The label does not prove sex, age, collection location, show grade or a fixed adult pattern. It also does not turn a two-fish order into a matched pair. Accurate expectations protect both the fish and the buyer: choose this listing for the species, Gold trade form and shell-dwelling behaviour, while allowing normal individual variation.

Adult size, shipping size and growth

FishBase records a maximum length of 5.8 cm total length. Total length includes the tail, so body length is shorter. Males can become more robust and may reach the upper end of the recorded size, but a size option cannot reliably determine eventual sex. Growth depends on genetics, age, feeding, temperature, social access to food and water quality.

The current Shopify Size choices are 2-3cm, 3-4cm and XL. These are dispatch-choice labels, not three different species and not promises of an exact measurement to the millimetre. The XL label does not state a precise centimetre range on this listing. If a narrow current size is essential for an established group, ask before ordering rather than inferring it from a photograph or the adult maximum.

Label	What it tells you	What it does not tell you
2-3cm	A smaller dispatch size band.	Sex, age, final colour, compatibility or adult size.
3-4cm	A larger measured dispatch size band.	A guaranteed male, female or breeding-ready fish.
XL	The supplier's larger available class.	An exact length unless confirmed for the current stock.

Tank size: prioritise the bottom footprint

For this fish, tank length and usable sandy floor are more informative than the litre number printed on a box. FishBase gives a 60 cm minimum aquarium length. Treat that as the floor for a species-focused setup, not as permission to crowd several territories into every 60 cm aquarium. Tall, narrow tanks can hold many litres while providing little additional shell-bed area.

A 60 cm-long aquarium can work for a carefully planned, lightly stocked shell-dweller setup with a clear separation plan. A 75-90 cm footprint is more forgiving when keeping more than one fish, creating more than one shell cluster or considering compatible open-water fish. Larger floor area lets the aquarist leave real gaps between territories and observe whether one individual is being pushed away from every refuge.

Do not convert the recommendation into a universal gallon slogan. Aquarium dimensions, shell layout, sex ratio, fish maturity and the number of defended sites all change social pressure. Start with the footprint, then check that total water volume, filtration and maintenance provide stable water.

Building a functional shell bed

Shells are not optional decoration. Research describes Ocellatus as an obligate shell dweller that uses abandoned snail shells for refuge, nesting and brood care. Both sexes manipulate a shell, orient it and move sand around it. A shell-bed aquarium therefore needs objects the fish can actually enter, turn around in and maintain.

Provide at least one safe, usable shell per fish and several additional choices. Spares matter because fish can reject a shell based on its internal geometry, opening or size, and because a single coveted shell can become a focus of repeated aggression. Scatter choices into distinct zones rather than placing every opening in one tight pile. Use hardscape or planting as sight breaks without blocking escape routes across the sand.

1. Place a smooth layer of fine sand across the intended shell area.
2. Offer shells of more than one appropriate size, each with an intact interior and a fish-safe opening.
3. Set some shells partly into the sand but allow the fish to reposition and bury them.
4. Keep openings visible and avoid wedging shells where a fish could be trapped.
5. Leave separation between clusters so every shell is not inside one dominant fish's immediate territory.
6. After adding fish, watch access to shells rather than assuming the original aquascape will remain acceptable.

Choosing and preparing shells safely

A suitable shell must be large enough for the fish to enter and reverse or turn safely, but not so damaged that sharp edges catch the body or fins. Current nest-building research found that Ocellatus prefers shells suited to its changing body size and responds to the shell's internal helical structure. That makes shell geometry a husbandry issue, not simply a visual theme.

Use clean, empty shells with no residue, fragrance, paint, varnish, metal coating or hidden animal tissue. Inspect the aperture and interior for chips. Rinse thoroughly in dechlorinated water and avoid household detergents. Shells collected outdoors can carry contaminants or unsuitable residues, so aquarium-sourced shells are the more controllable choice.

Check shells during maintenance. A shell can become filled with compacted waste, inaccessible under hardscape or monopolised by one fish. Do not routinely lift a fish out of its refuge for inspection. Instead, observe entry, exit, breathing, feeding and territory access; intervene only when there is a clear welfare reason.

Substrate, rockwork and plants

Use fine, smooth sand that can be lifted and shifted by a small cichlid. Coarse gravel frustrates normal digging, traps debris around shells and can create unstable gaps. A depth of roughly 4-6 cm across the working shell area gives the fish material to excavate and push, although the exact depth can be adapted to the tank structure. Keep the substrate shallow enough elsewhere to clean effectively.

Rockwork must be stable before fish dig underneath it. Place major rocks on the tank base or secure support, then add sand around them; do not balance heavy stone on loose substrate that the fish can remove. Create visual boundaries, but keep a broad open sandy zone around the shells. Sharp rock, narrow crevices and unstable piles add risk without improving the shell bed.

Plants are optional. Species adapted to hard alkaline water can be used around the edges, and attached plants can help preserve floor space. Expect digging near shell entrances, so delicate rooted stems may be moved. The representative gallery includes plants and driftwood, but it does not show a complete or prescriptive Ocellatus habitat. The aquarium should be designed from the fish's biological needs, not copied from the images.

Water chemistry for a Lake Tanganyika cichlid

FishBase records pH 8.0-9.0 and general hardness of 9-19 dH for L. ocellatus. These values reflect a fish adapted to mineral-rich alkaline water. Stability matters: a consistent pH of 8.2 is safer than repeatedly dosing the aquarium up and down in pursuit of 8.8. Measure the source water before buying and understand how the substrate, rock, salts and water changes affect it over time.

A practical home temperature target is 24-26°C. FishBase records 23-25°C; the slightly broader operating band recognises normal heater control while keeping the aim close to the recorded range. Avoid using the top and bottom as daily targets. Rapid temperature swings during water changes or transport can be more stressful than a stable value within a suitable band.

Parameter	Target	How to use it
Temperature	24-26°C practical target	Use a reliable heater where room conditions require it and verify with a separate thermometer.
pH	8.0-9.0	Keep stable; investigate a falling pH rather than repeatedly adding unmeasured buffer.
GH	9-19 dGH	Match mineralisation gradually and test the prepared change water when remineralising.
Ammonia	0 mg/L	Any detectable amount requires prompt investigation and corrective action.
Nitrite	0 mg/L	Detectable nitrite means the biological system is not safely processing the load.
Nitrate	Kept low and stable by stocking control and water changes	Use the trend to set a maintenance interval rather than relying on one universal number.

For a fuller explanation of GH, KH, pH and nitrogen compounds, use the aquarium water chemistry guide. Do not combine chemical products unless their effect on the source water is understood.

Cycling and testing before the fish arrives

A new aquarium is not safe simply because it has run for a set number of days. The filter must contain enough nitrifying bacteria to process the expected waste load while ammonia and nitrite remain at zero. Complete fishless cycling before ordering, test with a suitable liquid or calibrated method, and record results rather than relying on clear-looking water.

Test pH, GH and preferably KH as well as nitrogen compounds. A mature filter can still be paired with unsuitable soft, unstable water. If the source water differs strongly from the target, prepare and test the change water consistently. Large sudden corrections after fish are present can cause more harm than a measured gradual plan.

Before dispatch, confirm that the heater, filter, lid and test kits all work; shells are stable; and an emergency separation tank or divider is available. Territorial problems often become visible after introduction, so the backup must be cycled and ready rather than an empty container assembled after injury occurs.

Filtration, oxygen and water movement

Use mature biological filtration sized for the aquarium and stocking level. The outlet should circulate oxygenated water without blasting sand into every shell opening or forcing fish to fight a constant jet at the bottom. A sponge pre-filter can protect smaller fish and future fry from an exposed intake, but it still needs regular cleaning in removed aquarium water.

Good oxygenation and surface movement support the biofilter as well as the fish. Position flow so debris can be collected while quieter shell territories remain available. Dead zones behind rockwork and under dense shell piles can accumulate waste. Observe where uneaten food settles and adjust the layout or maintenance method rather than increasing flow until the fish cannot hold position.

Never replace all mature media at once or rinse biological media under chlorinated tap water. Service filters in stages, preserve bacterial surfaces and use dechlorinator for new water. If flow falls sharply, find the blockage; a filter that hums is not necessarily circulating enough water.

Routine maintenance without destroying territories

Set the water-change interval from measured nitrate trend, feeding, stocking and the buffering behaviour of the aquarium. Many well-managed setups use partial weekly changes, but the correct percentage is the amount that restores water quality without causing abrupt shifts in temperature or chemistry. Match the new water carefully and add it without collapsing shell entrances.

Siphon exposed areas of sand lightly and remove settled waste, but do not sterilise the shell bed at every service. The fish deliberately maintains its nest and may respond strongly when every shell is moved. Rotate deeper cleaning across zones, keep major territory landmarks where possible and return any accidentally disturbed shell with a usable opening.

• Test ammonia and nitrite whenever behaviour changes or filtration is disturbed.
• Record pH and hardness often enough to detect drift before it becomes a crisis.
• Remove uneaten food rather than allowing it to decay in a shell.
• Check heater function and actual temperature, not just the dial setting.
• Inspect filter flow, intake safety, rock stability and shell access.
• Watch every fish eat and return to a usable refuge.

Territorial behaviour and normal shell attachment

Ocellatus may spend time at, inside or immediately above a chosen shell. A fish can dart back to it when startled, move sand with its mouth, flare fins, face a neighbour, chase briefly or patrol a small area. Peer-reviewed work has even used the species' strong motivation to return to a home shell to study navigation. These behaviours make the fish compelling to observe, but they also mean shell access is a welfare requirement.

Normal territorial behaviour should not be confused with continuous persecution. Warning signs include one fish being kept in a top corner, barred from every shell, chased whenever it attempts to feed, breathing rapidly, losing weight or showing damaged fins. Add more shells only if the footprint can support distinct sites; dropping a new shell inside the dominant fish's existing territory may not help.

Rearranging boundaries can sometimes interrupt an established aggression pattern, but it is not a substitute for sufficient space or a compatible social plan. If one fish cannot establish a safe refuge, separate it promptly into mature suitable water.

Group planning, sex and the two-fish offer

The current buy box can present a two-fish quantity and calls it a "Breeding pair." That wording must not be interpreted as a biological guarantee. The Shopify Size option identifies size class only. It does not establish sex, and two juveniles cannot be promised to mature as one male and one female, accept each other or breed.

Published accounts describe flexible social and mating arrangements, while aquarium outcomes depend on sex ratio, maturity, territory structure and individual behaviour. Avoid treating "one male with two or three females" as a universal formula. Even when the sexes are known, each fish needs a usable shell and space outside a neighbour's immediate defence zone.

Ordering disclosure: a two-fish order means two fish of the selected size class. It does not guarantee an opposite-sex pair, a bonded pair, a compatible pair or a breeding result. Have a mature separation option ready.

Tank mates and compatibility

A species-focused shell bed is the clearest starting point. In the 60 cm minimum footprint, do not assume there is room for another shell-dwelling species simply because both remain small. Similar fish can compete for the same bottom area and shells. Combining Ocellatus with another shell dweller can create persistent border conflict that is difficult to resolve once every refuge is claimed.

In substantially larger Lake Tanganyika aquariums, experienced keepers may consider calm open-water fish whose adult size, group needs, diet and water chemistry are compatible. The upper water must offer real space beyond the shell territories, and the aquarium must support the complete social group required by the companion species. Avoid large predatory cichlids, highly aggressive bottom dwellers, fin-damaging fish and species requiring soft acidic water.

Scenario	Assessment	Conditions
Species-focused Ocellatus aquarium	Preferred starting point	Multiple shells, separated territories, observation and a backup separation plan.
Another shell-dwelling species in 60 cm	Avoid	Both species need the same limited bottom territory and refuges.
Calm open-water Tanganyika fish	Possible only in a substantially larger setup	Compatible chemistry, complete group size, open swimming space and no pressure on the shell bed.
Large or highly aggressive cichlids	Avoid	Size and aggression can overwhelm a small shell dweller.
Soft-water community fish	Usually unsuitable	The water-chemistry mismatch is enough reason not to combine them.
Shrimp or very small invertebrates	Not dependable companions	Ocellatus microfeeds on invertebrates and may hunt small animals.

Compatibility lists cannot override what is happening in the aquarium. Observe body condition, access to food, shell ownership and retreat routes every day. The cichlid care guide provides a broader planning framework, but the shell-bed requirements on this page remain specific to Ocellatus.

Feeding a micro-invertebrate feeder

FishBase describes the species as a microfeeder on invertebrates. In the aquarium, use a high-quality complete food made for small carnivorous or omnivorous cichlids as the nutritional base. Choose small sinking or slowly descending pellets or granules that the fish can take cleanly near its territory. Confirm that every fish eats; a subordinate individual may remain hidden while a dominant fish takes food from the whole shell bed.

Add variety with appropriately sized frozen or live foods such as cyclops, daphnia, brine shrimp, mysis pieces or similar clean aquarium foods. Bloodworm can be an occasional item if sourced and stored properly, but it should not become the only diet. Avoid feeder fish, wild-collected live food from uncertain water and large pieces that are swallowed poorly.

Feed measured portions that are consumed promptly. Small repeated meals can be useful for juveniles, provided filtration and maintenance keep pace. Remove food trapped inside empty shells. A rounded abdomen immediately after a meal is not a target to maintain all day, and repeated overfeeding can foul the very refuge where the fish spends most of its time.

Breeding biology without a breeding promise

Ocellatus lays eggs inside a shell. Current Biology research documents maternal care: the female tends eggs and larvae and helps maintain fresh water within the shell before the young emerge. Nest-building research also shows that fish position shells apex-down, cover them with sand and keep the aperture accessible. These are species behaviours, not proof that any two fish supplied together will reproduce.

Successful breeding requires mature compatible sexes, suitable shells, stable water, good condition and enough space for courtship and territorial boundaries. A female may spend extended time in the shell, but hiding alone does not confirm eggs. Do not lift or shake a shell to check. Watch feeding, ventilation behaviour and the area around the entrance from outside the aquarium.

Prepare fine first foods and intake protection before fry appear. Young fish emerging from a shell are vulnerable to filtration, tank mates and adult territorial changes. Breeding can rapidly increase stocking pressure, so a plan for grow-out space and responsible rehoming is part of the setup, not an afterthought.

Health observations and welfare signals

A settled fish should be alert, control its position, respond to food and use a shell without being trapped there by aggression. Colour can lighten during transport or social stress, so judge health from several signals rather than colour alone. Monitor breathing, posture, appetite, body condition, fins, faeces and the ability to enter and leave the refuge.

Observation	Possible meaning	First checks
Brief retreat into a shell	Normal refuge use after disturbance	Give quiet time and confirm the fish later resumes normal feeding and movement.
Constant surface or corner hiding	Aggression, unsuitable water, low oxygen or illness	Test water, inspect flow and watch interactions immediately.
Rapid breathing	Water-quality, oxygen, temperature, gill or stress problem	Check ammonia, nitrite, temperature and aeration before guessing a treatment.
Refusal of food	Recent transport, bullying, water problem or disease	Confirm water, privacy, shell access and whether every fish can approach food.
Frayed fins or missing scales	Territorial injury, decor damage or disease	Observe chases, inspect hardscape and separate if injury is continuing.
Swelling or abnormal buoyancy	Dietary, internal or water-quality problem	Stop speculative medication, document symptoms and seek informed diagnosis.

Do not combine medicines or add salt automatically. Lake Tanganyika chemistry is not a licence for unmeasured treatment. Diagnose from symptoms, history and water tests, follow the selected product exactly, and protect biological filtration where treatment instructions require it.

Arrival and acclimation

Have the aquarium fully heated, cycled and aquascaped before delivery day. Turn the main lights down, keep the room calm and prepare a net, container and water tests. Follow the current parcel instructions and use the guided acclimation timer as an on-site aid. Do not leave a sealed bag floating for an open-ended period while temperature and chemistry continue to change.

Transport water should not be poured into the display aquarium. Transfer the fish gently and allow it to find a shell without immediate competition for the only refuge. A new arrival may remain pale or hidden at first. The important early checks are controlled breathing, normal balance, freedom from active attack and eventual interest in food.

Biosecurity is valuable, particularly for an established collection, but there is no single fixed quarantine duration or prophylactic drug routine that suits every home. A separate mature observation tank with compatible hard alkaline water can reduce cross-contamination risk. Avoid placing a shell-dependent fish in a bare undersized container without refuge simply to follow a calendar.

Representative gallery: what the images show

The four gallery images are photorealistic illustrative representations based on a private low-resolution reference, not photographs of the exact individual that will be dispatched. They can help communicate the Gold Ocellatus form, but they do not prove sex, exact colour, current size or eventual markings.

The second image shows two similar fish in one planted scene. It is not evidence that those fish are a sexed pair, compatible pair or breeding pair. None of the four images shows a complete shell-bed setup, and the paired scene does not visibly show shells. Build the aquarium from the care requirements and scientific evidence on this page rather than copying the decorative scene.

• Expect natural variation in gold tone, fin edging, markings and proportions.
• Use the selected Size option for the dispatch band, not the apparent image scale.
• Do not infer sex from a gallery image.
• Do not use two fish in one illustration as compatibility advice.
• Provide real shells and fine sand even though the gallery does not show the full habitat.

Related shell dwellers to compare

Related listings are useful for comparing identity and appearance, but they are not automatically compatible tank mates. Each product requires its own adult-size, group, shell and water assessment. Do not mix species merely because they share the common name shell dweller.

• Signatus Shelldweller is a separate species and should be assessed independently.
• Meleagris Shell-Dweller has its own identity and social requirements.
• Ocellated Shelldweller is the non-Gold comparison listing.
• Blue Ocellated Shell-Dweller is a different commercial form; colour labels do not guarantee sex or compatibility.

Gold Ocellatus Shell-Dweller FAQ

Is Gold Ocellatus a separate species?

No. Gold is a commercial colour-form label for Neolamprologus ocellatus, widely known as Lamprologus ocellatus. Individual colour and markings vary, and the label does not establish sex, locality or show grade.

Why do some sources use Lamprologus ocellatus?

The species has a complicated genus history. Eschmeyer's Catalog currently accepts Neolamprologus ocellatus while recording valid published use of Lamprologus ocellatus and quoted 'Lamprologus' ocellatus. Aquarium sources often retain the familiar older combination.

What tank size does a Gold Ocellatus need?

Use at least a 60 cm-long species-focused aquarium, following the FishBase minimum length. Prefer 75-90 cm or more for several territories or any carefully selected companions. Floor area and shell spacing matter more than a litre figure alone.

How many shells should I provide?

Provide at least one safe, usable shell per fish plus several spares in different sizes and separated zones. Every shell must have an intact interior, a suitable aperture and enough surrounding sand for the fish to position it.

Can I keep Ocellatus on gravel?

Fine smooth sand is strongly preferred because the fish digs, positions shells and partially buries them. Coarse gravel restricts that behaviour and traps waste around the shell bed.

What temperature and pH are suitable?

A stable 24-26°C is a practical home target. Maintain pH 8.0-9.0 and general hardness around 9-19 dGH. FishBase records 23-25°C; avoid abrupt changes and do not chase the edge of a range.

Is this fish easy for a beginner?

It is better described as moderate. The fish remains small, but it requires a cycled aquarium, hard alkaline water, a functional shell bed and active management of territorial behaviour. A prepared first-time cichlid keeper can succeed, but the setup is specialised.

Does the two-fish option supply a breeding pair?

No sex or breeding outcome is guaranteed. The Size option identifies dispatch class only. Two fish may not be one male and one female, may not accept each other and may need separation. Treat the order as two unsexed fish unless the live variant explicitly states otherwise.

Can two males live together?

Do not plan around that assumption. Mature males can defend substantial shell territories. A larger footprint, multiple shell zones and sight breaks may reduce pressure, but any fish denied refuge or food must be separated promptly.

Can Ocellatus live with other shell dwellers?

Not in the 60 cm minimum. Different shell-dwelling species compete for the same bottom area and refuges. Mixed Tanganyika displays require a substantially larger aquarium, species-specific planning and an immediate separation option.

What should I feed a Gold Ocellatus?

Use a complete small cichlid pellet or granule as the staple, with suitably sized frozen or live invertebrate foods such as cyclops, daphnia, brine shrimp or mysis pieces for variety. Feed measured portions and ensure every fish gets access.

Will the fish look exactly like the gallery?

No. The four images are illustrative representations, not photographs of the exact dispatched fish. Gold tone, markings, fin edging, size, body proportions and sex vary. The two-fish image is not compatibility or breeding advice.

How do I know the aquarium is cycled?

Test it. The established biofilter must process the expected waste load while ammonia and nitrite remain at zero. The age of the aquarium or clear water is not proof. Also confirm stable alkaline pH and suitable hardness before ordering.

How should I acclimate a shell dweller?

Prepare stable matching water, dim the lights and follow the current arrival instructions without leaving the sealed bag floating indefinitely. Transfer the fish without adding transport water to the aquarium and give immediate access to a safe shell away from active aggression.

Is live-fish delivery guaranteed?

Eligible livestock orders are covered by the Tropical Fish Co Live Arrival Guarantee when the current policy conditions and evidence steps are followed. Read the delivery policy before ordering and inspect the parcel promptly on arrival.
