Longfin White Cloud Mountain Minnow (Tanichthys albonubes)

Longfin White Cloud Mountain Minnow is the flowing-fin aquarium form of Tanichthys albonubes, a small, active and social freshwater fish best kept in a cool, well-oxygenated aquarium. The extended fins give mature fish a more graceful outline than the standard form, while the familiar pale lateral sheen and red-toned fin markings can become especially attractive in a planted display. It is a practical choice for a keeper who wants an energetic shoal without maintaining the warmer temperatures required by many tropical community fish.

This is still a group-living species, not a decorative fish to keep alone. Plan for at least five, with eight or more preferred when the aquarium has enough swimming length, filtration and maintenance capacity. Select the live size option and then the quantity you need. One quantity means one unsexed fish; the gallery image showing two fish is illustrative and does not promise a pair, two fish or an established group. The shoal-pricing feature rewards suitable multi-fish orders but does not change the sale unit.

What the long-fin name means

The customer-facing identity is deliberately simple: this is a domestic long-fin form of the White Cloud Mountain Minnow, Tanichthys albonubes. Long-fin refers to selectively maintained extended finnage within aquarium stock. It is not a separate wild species, and the supplier has not provided a breeder line, collection locality or formal cultivar registration that would justify a more elaborate taxonomic label.

The supplier's concatenated suffix is not a valid scientific name and should not be interpreted as a relationship to an unrelated fish group. Current nomenclatural references recognise Tanichthys as a valid genus in Tanichthyidae, with T. albonubes as its type species. The listing therefore keeps the useful species identification and removes the unsupported suffix.

Wild populations assigned historically to the T. albonubes complex show meaningful geographic and genetic diversity. Peer-reviewed work has proposed cryptic species among wild populations, which makes unsupported locality claims even less appropriate. This captive trade fish is sold under the supplied T. albonubes identity; it is not represented as wild collected, locality pure or genetically assigned to a particular population.

What you receive and how to choose a size

Use the size selector for the options currently available. The displayed stock and price belong to the selected option and can change independently, so this description does not freeze either value into text. Supplier size bands are approximate commercial classes for living fish, not a millimetre-perfect promise. A fish may sit slightly above or below the stated band because body length, fin extension, age and natural variation do not fit a rigid manufactured measurement.

Choice	What it means	Planning point
Smaller size option	A younger or smaller fish with more growth and fin development still ahead	Choose companions of a safe size and make sure the fish can reach food without competition
Larger size option	More immediate visual presence and usually more developed finnage	It still needs a proper group, swimming length and gradual acclimation
Quantity one	One unsexed fish from the selected size option	It is not a pair, six fish or a complete shoal
Multiple quantities	The number of individual fish shown in the basket	Check that the mature aquarium supports the whole group before ordering

The first listed size may be unavailable while another option remains in stock. Read the live selector rather than assuming that the first photograph, first size or lowest displayed price describes every variant. If you are replacing a lost member of an established group, compare body size carefully and consider quarantine before introducing the new fish.

Who this fish suits

This minnow suits a keeper who can provide a cycled aquarium, stable cool-to-temperate water, a real social group and regular testing. It works especially well in a planted 60 cm or longer aquarium where open swimming lanes are balanced with cover. The activity level makes a small display feel lively, while the long fins add detail without changing the species into a slow ornamental centrepiece.

It can be a sensible early species for a prepared beginner, but “hardy” should never mean expendable or suitable for an uncycled tank. A mature filter is essential. Ammonia and nitrite must read zero before the fish arrives. The keeper also needs a plan for temperature during both winter cold spells and summer heat, because a heater-free aquarium is only safe when the room stays inside the fish's range.

This is not the right choice for a warm 26-28°C community, a bowl, a tiny cube, an outdoor container exposed to UK weather without a seasonal management plan, or a tank dominated by fin nippers and predators. Use our White Cloud Mountain Minnow guide when you want broader species context, and compare the cool-water fish collection when planning a lower-temperature aquarium.

Tank size and swimming space

OATA recommends at least 45 litres for a small shoal of the smaller danio and White Cloud types. FishBase also records a 60 cm minimum aquarium length. Those measures describe a welfare floor, not an invitation to fill every litre. These fish are small but active, and they use horizontal space continuously. A longer aquarium gives the group room to move, display and separate without colliding with decor.

For most homes, 60 litres or more is the more forgiving target. Extra water volume slows temperature and chemistry changes, gives the filter more margin and makes it easier to keep eight or more fish. Increase volume and length again when adding another species, keeping a larger shoal or building a heavily planted layout that reduces open water. Check a proposed aquarium with the tank volume calculator, but use dimensions and behaviour alongside the litre result.

Aquarium plan	Assessment	Why
Under 45 litres	Not recommended for the permanent group	Limited swimming length and less stable temperature and water quality
45 litres, 60 cm long	Minimum for a carefully managed small shoal	Meets the evidence-led floor but leaves limited margin for companions
60-80 litres	Better practical starting point	Supports a fuller group, more stable water and a balanced planted layout
Larger long aquarium	Best for a larger shoal or compatible community	More swimming room, visual separation and maintenance capacity
Tall narrow aquarium	Less useful than a longer tank of similar volume	The fish benefit more from horizontal swimming length than extra height

Group size and natural behaviour

White Clouds are social fish. OATA advises at least five and notes that more is better; FishBase likewise records groups of five or more. The store recommendation is eight or more where the aquarium can support them. A fuller group usually gives more confident open-water activity and a wider range of harmless displaying behaviour, while a lone fish or a pair can become withdrawn and stressed.

A social group does not move as one tight formation every minute. Settled fish may spread through the open water, regroup when startled and display to one another. Males in breeding condition can become brighter and may perform short chases or fin displays. That activity should be brief and distributed, not one fish being relentlessly pinned in a corner or prevented from feeding.

Group size cannot be separated from tank size. Adding more fish to solve nervous behaviour only works when filtration, swimming space and maintenance also scale up. Observe whether every fish can feed, rest and move normally. If one individual stays isolated, clamps its fins or loses condition, test the water and review health and social pressure rather than dismissing it as a quiet personality.

Temperature and the unheated-aquarium question

A stable 17-23°C is the conservative working range from OATA, with FishBase recording 18-22°C. This is cooler than many fish sold from tropical systems. A heater is not automatically required if the room keeps the aquarium reliably inside that range, but “unheated” does not mean uncontrolled. Measure the water at its coolest winter point and during summer heat rather than relying on the room thermostat.

Situation	Recommended response
Room remains stable within 17-23°C	An unheated aquarium can be suitable; continue monitoring with a reliable thermometer
Room regularly falls below range	Use a guarded, thermostatic heater set conservatively to prevent cold dips
Aquarium is near a window, radiator or draught	Move it or shield it from abrupt temperature changes before adding fish
Summer water approaches or exceeds 23°C	Increase safe surface movement, reduce heat sources and monitor oxygen and fish behaviour closely
Warm-water companions need 25-28°C	Choose different companions rather than keeping White Clouds chronically too warm

Temperature changes should be gradual. Cool water can hold more oxygen than warm water, so an unexpected summer rise can combine heat stress with reduced oxygen availability. Keep the filter operating, maintain surface movement and have a safe heat-management plan. Do not drop frozen bottles directly into the tank or make large sudden changes that replace one problem with thermal shock.

pH, hardness and water quality

Use pH 6.5-8.0 and 4-12 dGH as a conservative practical range, while recognising that FishBase records a somewhat broader species range. Stable, conditioned water inside a suitable range is better than repeated chemical adjustment towards one supposedly perfect number. Test the source water first, then decide whether the aquarium can remain stable without elaborate treatment.

Ammonia and nitrite must be zero. OATA advises keeping nitrate no more than 20 mg/l above the normal tap-water level. Nitrate is not a substitute for the other tests: a low nitrate result does not prove that a new filter is cycled, and clear water can still contain toxic ammonia or nitrite. Our water parameter matcher can help organise a compatibility check, but use current test results from your own aquarium.

Parameter	Target	Action if wrong
Temperature	17-23°C, stable	Correct the environmental cause gradually and increase observation
pH	6.5-8.0	Check source water and buffering before using chemical adjusters
General hardness	4-12 dGH	Make changes only with a repeatable source-water plan
Ammonia	0 mg/l	Treat any detectable result as urgent; protect fish and biological filtration
Nitrite	0 mg/l	Treat any detectable result as urgent and review cycling or filter disruption
Nitrate	No more than 20 mg/l above tap baseline	Increase appropriate water changes and reduce accumulated waste

Filtration, flow and oxygen

A filter is essential. Choose mature biological capacity for the full group and enough mechanical capture to remove suspended waste without creating a violent jet. OATA recommends a moderate current to support oxygenation, but long-fin fish should still be able to hold position and feed comfortably. Spread the return flow across the aquarium or use a spray bar if one narrow outlet overwhelms the fish.

Leave visible surface movement. The exact filter type matters less than reliable circulation, biological maturity and maintainability. Sponge, internal, hang-on-back and external filters can all work when sized and arranged correctly. Protect intakes where a smaller fish could be trapped, and make sure decor does not create stagnant pockets that collect food.

Read our aquarium filtration guide before changing media or replacing a filter. Biological bacteria live on wet surfaces, so throwing away all mature media at once can cause an ammonia or nitrite spike. Rinse reusable media in removed aquarium water where appropriate, keep it wet during maintenance and avoid cleaning every stage on the same day.

Plants, substrate and layout

Natural habitat records describe clear or clean, slow-moving streams with abundant hydrophytes. A home aquarium does not need to copy one collection site literally, but plants and visual shelter fit the species well. Combine planted edges and background cover with a broad open swimming lane. Fine-leaved plants can also receive exploratory attention and, in a breeding setup, scattered eggs.

Element	Useful approach	Avoid
Substrate	Sand or smooth fine gravel that can be cleaned easily	Sharp material or deep dirty zones that trap food
Planting	Dense margins with open central or front swimming space	Filling every lane with hardscape or stems
Wood and stones	Stable, smooth pieces that create cover without snagging fins	Rough edges and narrow gaps around extended finnage
Lighting	A predictable day-night cycle with shaded areas	Sudden intense lighting over a bare aquarium
Lid	A secure fitted cover with safe cable and filter gaps	Large openings over an active small-fish aquarium
Swimming room	Clear horizontal lanes through the middle and upper water	A tall decorative layout with little usable length

A darker background and healthy planting can make the pale stripe and red fin details easier to see, but colour is not a reason to compromise cleaning access. Leave enough room to siphon waste and inspect every fish. Wash new decor safely, avoid metal or unknown coatings and secure anything that could shift during maintenance.

Feeding a healthy group

White Clouds are omnivorous. FishBase records zooplankton and detritus in natural feeding, while OATA recommends flake or granules with small live or frozen foods. In the aquarium, use a complete small-fish food as the nutritional base and add appropriately sized variety. Long fins do not require a special branded diet; consistent balanced nutrition and clean water matter more than promotional ingredients.

Food type	Role	Practical boundary
Quality flake	Convenient complete staple when crushed to a suitable size	Feed only what the group takes promptly
Small granules or micro-pellets	Measured staple with less surface drift	Check that particles are small enough for every fish
Suitable frozen food	Variety and feeding enrichment	Thaw and portion hygienically; remove leftovers
Suitable live food	Occasional behavioural enrichment	Use a trusted source and consider pathogen risk
Vegetable or algal content	Part of a varied omnivorous diet	Do not assume grazing alone supplies complete nutrition

OATA advises feeding once daily and offering only what is eaten within a few minutes. Adjust the exact portion to group size, food density, temperature and body condition. Scatter small amounts across more than one point so timid fish can feed. A rounded full abdomen immediately after a meal is different from persistent swelling; observe the fish before and after feeding rather than continually adding food.

Uneaten food becomes a water-quality problem. If food reaches the substrate untouched, reduce the next portion and remove the residue. During the first days after delivery, a small fish may need quiet and familiar-sized food, but repeated refusal should trigger checks of temperature, ammonia, nitrite, breathing and social pressure.

Choosing compatible tank mates

Compatibility begins with temperature. A peaceful fish that needs 26°C is not a good long-term match simply because it does not attack minnows. Choose species that genuinely share the 17-23°C range, remain small enough not to hunt them, and will not nip the extended fins. Compare adult size, group needs, swimming level, feeding speed and water chemistry before buying.

Candidate	Assessment	Reason
More White Cloud Mountain Minnows	Best first addition	Builds the required social group with matching husbandry
Standard-fin White Clouds	Potentially compatible	Same species-level care, but buy the intended form and avoid confusing product identities
Gold White Clouds	Potentially compatible	Same species form with similar cool-water requirements; account for the full combined group
Vietnamese White Clouds	Possible only after species-level checks	A related but distinct species with its own group and care considerations
Small peaceful cool-tolerant fish	Case by case	Confirm exact temperature, adult size, behaviour and group requirements
Persistent fin nippers	Avoid	Extended fins can attract repeated damage and stress
Large goldfish or predatory fish	Avoid	OATA warns that larger goldfish can eat small minnows
Warm-only tropical species	Avoid	Chronic high temperature sacrifices the White Cloud's preferred conditions

Long-fin care considerations

The long-fin form follows the same core species husbandry, but its extended finnage deserves a little extra attention. Avoid rough decor, intake slots that can trap a small fish and companions known for persistent fin nipping. Provide current for oxygen and normal activity without forcing the fish to fight one concentrated outlet all day.

Fin length varies. A juvenile may not yet show the same extension as a mature representative image, and not every individual develops identical rays, colour or symmetry. Minor natural differences are expected. Torn, frayed or clamped fins are different from normal variation and should prompt a review of water quality, physical hazards, aggression and possible disease.

Do not keep the fish alone merely to protect its fins. Social welfare still matters. A well-planned group with suitable companions, smooth decor, clean water and distributed feeding is safer than isolating one specimen in a small uncycled container.

Appearance and gallery-image boundary

Long-fin White Clouds are valued for movement as much as colour. The body is slender, with a light-reflecting lateral area and red or orange accents often visible around the fins. Extended dorsal, anal and caudal rays can give the fish a more flowing silhouette. Colour and fin development vary with age, genetics, condition, lighting, background and stress.

All four retained gallery images are representations based on the product identity. They are not photographs of the exact fish selected for dispatch. One image shows two fish to illustrate social presentation, but it is not a pair or quantity promise. The fish you receive may be paler after transport and can look different as it settles, grows and develops.

The accurate buying promise is therefore the listed identity, live size option and quantity, not an exact rendered pattern or fin shape. No sex, individual colour placement, adult fin length or breeding status is guaranteed. This disclosure protects the customer from treating a representative gallery as a specimen-level photograph while preserving the useful visual guide.

Sex, courtship and breeding

Sex is not guaranteed. OATA notes that sexing is difficult unless fish are in breeding condition; females may look fuller, while spawning males can be slimmer and brighter. Those are tendencies, not a reliable retail method for every juvenile. A rounded fish after feeding is also not proof of sex.

White Clouds are egg scatterers. In a mature group, brief displays and spawning among fine plants may occur without intervention. If the aim is to raise fry, use a separate planned breeding setup with suitable spawning media and appropriately small first foods. Adults may eat eggs or newly hatched fry, and a general display tank is not a controlled breeding environment.

Buying two fish does not create an established pair, and the gallery does not imply one. For a healthy display, buy for social-group welfare rather than trying to obtain a guessed male and female from appearance alone. Breeding requires spare capacity for adults, eggs and juveniles, plus a plan for the resulting fish.

Preparing for delivery and acclimation

Prepare the aquarium before dispatch day. Confirm that the filter is mature and operating, temperature is stable, ammonia and nitrite are zero, the lid is secure and the intended group size is appropriate. Avoid major filter cleaning, substrate replacement or a large chemistry adjustment immediately before adding livestock.

1. Inspect the parcel and fish promptly on arrival, following the current reporting instructions before discarding packaging.
2. Keep the room calm and aquarium lighting low to reduce visual stress.
3. Follow the supplied acclimation instructions and use the acclimation timer to keep the process deliberate.
4. Match temperature and water conditions gradually without leaving the fish in deteriorating transport water for an unnecessarily long time.
5. Transfer the fish while adding as little transport water to the aquarium as practical.
6. Watch breathing, balance, schooling response and fin position closely during the first day.
7. Offer a small suitable feed only after the fish has settled, and remove anything ignored.

Our new-fish acclimation guide explains the planning principles in more depth. Quarantine is recommended when mixing livestock from different sources. A quarantine aquarium must itself be mature, filtered, covered and temperature controlled; an unstable spare container can create more risk than it prevents.

Daily and weekly maintenance

Successful care is a routine rather than a one-time setup. Observe the group daily and test regularly. OATA recommends weekly water-quality checks. The water-change schedule should keep nitrate and visible waste controlled without causing abrupt shifts in temperature, pH or hardness. Condition tap water and match replacement temperature before it enters the aquarium.

Frequency	Checks and actions
Daily	Check temperature, filter flow, breathing, balance, fin position, activity and whether every fish feeds
Several times weekly	Remove uneaten food and obvious waste; inspect intakes and surface movement
Weekly	Test ammonia, nitrite, nitrate and pH; check hardness as needed; complete an appropriate conditioned water change
During filter maintenance	Preserve biological media, rinse reusable media appropriately and avoid replacing all mature stages at once
After adding fish or changing feeding	Increase testing temporarily because biological demand has changed
Seasonally	Review the coldest winter and warmest summer temperatures and adjust the environmental plan

Read the nitrogen-cycle guide if ammonia or nitrite appears, or before setting up the first aquarium. Do not use fish to cycle a tank. If a reading is unsafe, protect the livestock with correctly matched water changes and address the filter or stocking cause rather than relying on a bottle to hide the result.

Health signs and early warnings

A healthy fish should be alert, balanced, interested in food and able to swim with the group. Its fins should normally be open rather than tightly clamped, eyes should be clear and breathing steady. Fresh arrivals may be subdued temporarily, so judge recovery through a combination of behaviour, feeding and water tests rather than colour alone.

• Test immediately if fish gather at the surface, breathe rapidly or lose normal balance.
• Check temperature and oxygenation during warm weather or after equipment changes.
• Investigate repeated flashing, white spots, sores, frayed fins, swelling or progressive weight loss.
• Review social pressure if one fish is continually isolated or prevented from feeding.
• Do not medicate by guesswork. Confirm water quality first and seek qualified aquatic-veterinary or experienced specialist advice.
• Use separate nets and siphons for quarantine where practical to reduce cross-contamination.

Long fins can show physical damage earlier than short fins, but damaged edges do not identify the cause by themselves. Poor water, fin nipping, sharp decor, transport injury and infection require different responses. Record when the change began, photograph progression and avoid mixing treatments without a diagnosis.

Longfin, standard and gold White Clouds compared

These forms share a species-level care foundation, but they are separate products and should remain clearly labelled. The long-fin listing is for extended-finnage stock. The standard form has the familiar shorter outline, while the gold form emphasises a pale gold or pinkish body colour. The Vietnamese White Cloud is a different species and should not be presented as another colour form.

Fish	Identity	Main visual distinction	Buying boundary
Longfin White Cloud	Domestic long-fin T. albonubes	Extended finnage and flowing profile	This listing; one unsexed fish per quantity
Standard White Cloud	Standard-fin T. albonubes	Shorter natural-style fin outline	Separate product and size options
Gold White Cloud	Gold colour form of T. albonubes	Paler gold to pinkish body presentation	Separate product and availability
Vietnamese White Cloud	Tanichthys micagemmae	Related small Tanichthys species with its own pattern	Do not describe as the same species or merely a colour form

Mixing compatible forms may be possible in a properly sized aquarium, but do not use that possibility to dilute group planning or product identity. Confirm the adult group total, quarantine new arrivals and choose the actual form you want. The long-fin variant is not an upgrade that makes standard fish inferior; it is a different visual preference with the same need for good welfare.

Browse the Danio, Rasbora and Tanichthys collection to compare current stock, but verify the exact care range of every species rather than treating a shared shop category as proof of compatibility.

Evidence and care sources

This listing separates live supplier and Shopify facts from broader species-level husbandry. Supplier evidence supports the long-fin trade identity, approximate size classes and a broad 18-25°C, pH 6.0-8.0 and 5-20 dGH range. The store uses the more conservative overlap from UK welfare and scientific sources:

• OATA: care for danios and White Cloud Mountain Minnows for UK temperature, chemistry, group, aquarium, filtration, feeding and acclimation guidance.
• FishBase: Tanichthys albonubes for accepted identity, family, size, distribution, habitat, group and aquarium-length context.
• Eschmeyer's Catalog of Fishes: Tanichthys for current genus validity and family placement.
• Peer-reviewed Hainan habitat study for evidence of a clean sluggish stream with abundant hydrophytes.
• Peer-reviewed research on cryptic diversity in the T. albonubes complex for the boundary against unsupported locality or lineage claims.

Care ranges are planning tools, not a substitute for testing the actual aquarium. Supplier packing quantities are trade logistics and are not the number of fish supplied to the customer. Live variant identifiers, prices and inventories remain controlled by Shopify and are not rewritten into this educational body.

Frequently asked questions

Is a Longfin White Cloud Mountain Minnow a separate species?

No. It is a domestic long-fin form of Tanichthys albonubes. The extended fins are an aquarium strain characteristic, not evidence of a separate species or subspecies.

What do I receive when I select quantity one?

You receive one unsexed fish from the selected live size option. The photograph showing two fish is illustrative and does not mean two fish or a pair are supplied.

Does the shoal price mean six fish are included?

No. Shoal pricing is a multi-buy feature. The basket quantity is the number of individual fish ordered, so select enough fish deliberately for your group and aquarium capacity.

How many should I keep together?

Keep at least five. Eight or more is preferred where aquarium size, filtration and maintenance allow, because a fuller group usually behaves more confidently.

What is the minimum tank size?

Use at least 45 litres and 60 cm of aquarium length for a small shoal. A 60-litre or larger long aquarium is a better practical target for a fuller group, stable water or companions.

Do Longfin White Clouds need a heater?

Not always. An unheated aquarium can work when the water remains steadily within 17-23°C. Use a thermostatic heater to prevent cold dips if the room falls below range, and monitor summer heat as well.

What temperature should I use?

Keep a stable 17-23°C. FishBase records 18-22°C, so the high teens to low twenties provide a sensible centre rather than a warm tropical setting.

What pH and hardness are suitable?

A practical range is pH 6.5-8.0 and 4-12 dGH, with ammonia and nitrite at zero. Stable tested water matters more than repeatedly chasing one exact pH value.

Are they good beginner fish?

They can suit a prepared beginner with a mature cycled aquarium, proper group and testing routine. They are not suitable for fish-in cycling, bowls or an uncontrolled room-temperature setup.

How large do they grow?

Plan for about 4-5 cm body length. The extended fins can make a mature long-fin fish look larger and more flowing than the standard form.

Will my fish look exactly like the gallery images?

No. The retained gallery images are representations. Real fish vary in colour, fin development and markings, and may look subdued immediately after transport.

Can I choose a male or female?

No sex is guaranteed. Differences are most apparent around breeding condition and are not reliable enough to promise the sex of every retail fish.

What should I feed them?

Use quality flake, small granules or micro-pellets as a balanced staple, with appropriately sized frozen or live foods for variety. Feed a measured amount eaten promptly.

Can they live with tropical fish?

Only with species that genuinely share the cooler 17-23°C range and do not nip fins, hunt small fish or overwhelm them at feeding. Many warm-only tropical fish are unsuitable.

Can longfin and standard White Clouds live together?

They share species-level care and may be compatible in a suitable aquarium. Still account for the whole group, protect extended fins from nipping and buy the intended form from its separate listing.

How should I acclimate delivered fish?

Prepare stable, tested water in advance, keep lighting low and follow the supplied instructions promptly. Match conditions gradually without leaving fish in cooling, deteriorating transport water.

Does the Live Arrival Guarantee apply?

Eligible livestock orders are covered subject to the current reporting window, photographs, destination and other conditions shown on the delivery and returns pages.

Can a first-time customer use WELCOME10?

Eligible first-time customers can use WELCOME10 for 10% off at checkout, subject to the current discount terms and exclusions.
