Rubricatochromis guttatus

Overview

Rubricatochromis guttatus is the accepted scientific name for the West African fish long sold in the aquarium trade as Hemichromis guttatus. The jewel cichlid genus overview explains the older trade grouping, while the accepted name distinguishes the true jewel-cichlid branch. It belongs to the cichlid family: compact, strongly marked fish whose colour and purposeful behaviour can make them the centre of a carefully planned aquarium. This is not a background community species. Its adult footprint, territorial nature and pair-forming behaviour deserve attention before the fish comes home.

One purchase supplies one live fish. Two recurring dispatch sizes are represented on this listing: 3.5–5 cm and 5–7 cm. The size you select is the size supplied, not the adult size. The FishBase species summary records a maximum of 12.0 cm standard length for a male or unsexed fish. Standard length is the measurement reported by that record; it should not be confused with either dispatch grade or an exact promise about the length of an individual adult.

The natural record places this species in African coastal drainages from Sierra Leone to Cameroon, excluding the Lower Volta basin. It is associated especially with vegetated, quieter water: shallow sections of larger rivers, small lateral tributaries, oxbow lakes and swampy habitats. Freshwater and brackish occurrences are both recorded, but a wild environmental record is not an instruction to add salt or to imitate every extreme in an aquarium. The practical aim is stable, clean water and a layout that lets a territorial cichlid use cover.

FishBase describes R. guttatus as aggressive, omnivorous, pair-bonding and a substrate brooder. Those four facts explain much of its appeal and much of the work involved. A settled individual is alert and engaging; a breeding pair can organise the aquarium around a defended spawning area. Space must therefore be judged as usable territory rather than litres alone. Cover, caves, wood, plants and open feeding room all have a part, but every feature must leave the keeper able to observe both fish and intervene if chasing becomes relentless.

Sex is guaranteed only when the selected option explicitly states male or female. This Hemichromis guttatus listing has no sex-guaranteed option. Colour, markings, size and maturity vary naturally, and a photograph is not a reliable promise of sex or of the exact adult appearance. Gallery images have been digitally enhanced to improve image quality. Natural colour, pattern, size and maturity can vary between live animals.

Before choosing this fish, compare the adult plan with the current African cichlid collection and decide whether you want a species-focused display, a carefully managed pair, or a larger mixed layout with a genuine fallback. The right question is not simply whether another fish fits today; it is whether every inhabitant will retain feeding access and a safe route away when a jewel cichlid claims space.

Care and aquarium planning

Build around the adult fish

A dispatch length of 3.5–5 cm or 5–7 cm describes the animal at supply, not the finished aquarium requirement. Begin with the 12 cm SL record, then allow for a cichlid that creates and defends territory. Floor area, the position of cover and the relationship between open and sheltered zones matter more than an attractive empty volume figure. A long aquarium offers more scope for separate areas than a tall, narrow one of similar litres, while a clear front view helps you notice when normal displaying turns into persistent exclusion.

If this will be your first aquarium, mature the biological filter before livestock arrives. The first tropical tank guide explains the sequence from setup to a functioning aquarium. A filter is not only a device that moves water. The RSPCA aquarium welfare guidance explains that beneficial bacteria convert toxic ammonia first to nitrite and then to the safer nitrate. A newly installed filter or one whose bacterial population has been damaged cannot be assumed to handle a full waste load immediately.

Arrange cover without losing observation

The species record associates R. guttatus with stands of emergent or submerged plants and with shallower, quieter habitats rather than rapids. In the aquarium, combine sheltered places with clear feeding and swimming room. Wood, robust planting, stable stones and cave-like structures can divide the floor into recognisable areas. Every item should be aquarium-safe, secure against digging and positioned so waste and the fish remain visible.

Cover has two purposes. It gives a subordinate fish somewhere to pause outside the most valuable area, and it gives a keeper visible clues about how space is being used. A fish that chooses shelter but still emerges to feed is different from one pinned into a corner and repeatedly attacked whenever it moves. Do not let dense decoration hide a worsening relationship for days. Inspect behind wood and around cave entrances during routine observation.

Plants may help create a calmer, more complex layout, but no plant can make an unsuitable social combination safe. Choose robust planting and accept that an active substrate-brooding cichlid may disturb the floor around a preferred site. Keep heater guards, filter intakes and sharp edges in mind when arranging enclosed spaces. A retreat must have an exit that the fish can actually use; a narrow ornament that allows one animal to trap another is counterproductive.

Use stable water, not a chase for perfect numbers

For this product, focus on mature biological filtration and stable conditions you can measure rather than a borrowed range. The wild record includes freshwater and brackish occurrences, but that describes habitat rather than prescribing salt for the aquarium. The water chemistry guide explains the main measurements, while the water matcher helps compare products that carry published care values. This fish still needs a plan based on its own adult size and territorial behaviour.

A mature, maintained biological filter is essential. The RSPCA aquarium welfare guidance explains that fish waste produces toxic ammonia, beneficial bacteria convert it to toxic nitrite and the filter ultimately produces the safer nitrate. Check ammonia and nitrite whenever behaviour changes or filtration has been interrupted, and do not assume clear water proves that the aquarium is biologically ready.

Aggressive cichlids can create extra waste by scattering food or disturbing the substrate. Remove uneaten food, siphon accessible debris and watch whether flow still reaches the places where waste accumulates. The best filter is one sized and maintained for the real stocking load, with outlets arranged so that the fish can use both sheltered and more open water. The species occurs in quieter habitats, so there is no need to turn the whole aquarium into a torrent simply to increase turnover.

Feed an omnivore, not a caricature

FishBase records R. guttatus as omnivorous. Choose a complete food intended for omnivorous cichlids, use a particle size the supplied fish can take and follow the product directions. Judge the amount from condition, feeding response and uneaten food rather than pushing an intensive schedule or an all-meat menu.

Offer an amount the fish can finish without leaving food to decay. Watch who actually eats: a dominant fish taking the first food does not prove that a quieter fish has received enough. Spread the suitable portion across more than one point only when needed, then remove leftovers rather than compensating with a large excess. An established fish that abruptly stops feeding deserves a water-quality check and closer inspection.

A growing dispatch-size fish needs consistent nutrition, but fast growth is not a reason to push oversized meals. Condition is judged over time by a full but not distended body, purposeful behaviour and steady feeding response. Avoid promising that any particular food will create the intense breeding colour seen in some jewel-cichlid imagery. Genetics, maturity, social state, lighting and individual condition all affect appearance.

Watch behaviour as closely as test results

Changes in swimming, colour, temperament, breathing, body condition, skin, fins and appetite are useful prompts to inspect the aquarium. With a territorial species, a social problem may first appear as hiding, missed meals, damaged fins or a fish hovering in an unusual place. Test ammonia and nitrite whenever several animals change together, and inspect pursuit and feeding access when one fish alone loses its normal routine.

• Normal information: a fish explores, feeds, uses more than one part of the aquarium and responds to activity without spending the day in frantic escape.
• Review the layout: one fish repeatedly blocks another from food, the filter outflow or every sheltered area.
• Act promptly: a fish is injured, breathing abnormally, pinned into a corner or unable to feed without being attacked.
• Check water first: several animals change behaviour at once, lose appetite or breathe faster than usual.

Do not medicate merely because colour darkens or a fish hides after a change. Those signs have many possible causes. Check water, temperature, recent maintenance and social interactions, document what you see and seek appropriate aquatic-veterinary or specialist help where necessary. A treatment choice, dose and duration are beyond the evidence for this listing.

Arrival and the first day

Be at the address for the confirmed delivery and prepare the aquarium before the parcel arrives. The store's current delivery and Live Arrival Guarantee policy says the parcel should be opened and inspected on the day it arrives. If a claim is needed, the evidence must be a continuous video beginning with the parcel still sealed, showing the outer box, the opening and the fish still in the sealed bag. Record that sequence before opening the fish bag or starting acclimatisation.

1. Have the mature aquarium ready and be present to receive the live-animal parcel.
2. Record the continuous sealed-parcel opening so the condition of the fish in the sealed bag is documented.
3. Inspect the fish promptly while it remains in the bag and contact the store the same day if anything is wrong.
4. Float the sealed bag for 20–30 minutes to equalise temperature.
5. Release the fish without pouring transport water into the aquarium, then observe its breathing, balance and ability to find shelter.

Keep the first observation calm. A newly moved cichlid may initially choose cover, but it should not be introduced into an aquarium where an established territorial fish can attack it immediately. The social plan should already include a low-stress introduction and a separation option. Delivery policy, acclimatisation and later husbandry are different questions: the first protects the animal through transfer, while the second sustains it for the months and years ahead.

Plan maintenance around what you can observe

Before routine maintenance, observe where the fish rests, which route it uses to feed and whether another animal changes course to avoid it. Inspect filter flow and test the aquarium if behaviour has changed. Remove accessible waste without dismantling every shelter, because repeated wholesale rearrangement can alter territorial boundaries. If filter material needs attention, preserve the beneficial bacteria and confirm that the filter restarts correctly.

Use a pre-purchase checklist

• Is the aquarium mature, filtered and already stable at measured values?
• Does the footprint suit a 12 cm SL territorial cichlid rather than only the dispatch-size fish?
• Can every current inhabitant reach food and shelter without entering one defended corner?
• Is there a separate mature backup aquarium available if relationships fail?
• Will someone be present on the confirmed delivery day and know the sealed-parcel video sequence?
• Are prepared omnivore foods and appropriately sized supplementary foods ready?

This checklist turns a visually appealing fish into a practical decision. A mature aquarium and accurate tests handle the environmental side; layout, observation and separation capacity handle the social side. Neither can compensate for the absence of the other. It is easier to leave extra room at the beginning than to create it after a cichlid has established the whole aquarium as its territory.

Read colour and activity in context

Jewel cichlids are valued for vivid appearance, yet colour alone is a poor health diagnosis and a poor sex test. Lighting, background, maturity, social state and individual variation can all alter what the keeper sees. Compare the fish with its own recent baseline: appetite, breathing, posture, fin condition and use of space provide more useful information than trying to match a gallery image shade for shade.

Breeding condition can coincide with stronger colour and more determined territorial defence. That does not prove the sex of a newly arrived fish, nor does it guarantee a compatible pair. If colour changes alongside rapid breathing, clamped fins, lost appetite or hiding, test the water and inspect social interactions. If the only change is a brighter fish guarding a substrate while both animals remain in good condition, prepare for the possibility of spawning behaviour and review the compatibility plan.

Compatibility and behaviour

Start from territorial behaviour

FishBase calls R. guttatus aggressive and says it requires sufficient space to build territories. That is the starting point for compatibility, not a footnote added after choosing companions. A fish can appear tolerant while young, unsettled or outside breeding condition and still become much more forceful later. Long-term planning must therefore consider the adult fish and the possibility of a defended spawning area.

No named species can be guaranteed as a universal companion from the evidence here. Similar water values are only one part of compatibility. Size, speed, body shape, feeding style, confidence and use of the same part of the aquarium all matter. A fish that shares the right pH may still be unable to leave a cichlid's territory, while an otherwise robust fish may constantly challenge it.

Keeping one fish or considering a pair

A single fish removes pair conflict and breeding-territory escalation, but it does not make every community combination safe. It still needs an aquarium designed around its adult size and territorial behaviour. A pair is not created simply by placing two unsexed fish together. The listing has no sex-guaranteed choice, and neither colour nor a photograph establishes sex.

FishBase describes the species as pair-bonding and a substrate brooder. A compatible pair may defend eggs and young vigorously. Watch both partners rather than assuming that a bond prevents aggression between them. If one fish loses feeding access, remains hidden or collects damage, the keeper must be ready to separate them.

Breeding information is useful because it predicts behaviour; it is not an invitation to produce fry without a destination and sufficient rearing space. FishBase reports that spawning can involve up to 300 eggs, with hatching after about two days and young free-swimming after about five. Those observations explain why parental defence can intensify quickly. The practical lesson is to leave room around a preferred substrate and avoid crowding the breeding territory with animals that will repeatedly approach eggs or fry.

Mixed aquariums need more than a list

If attempting a mixed layout, choose the aquarium and stocking order conservatively. Avoid combinations in which a small, slow or delicate animal must pass the cichlid's shelter to eat. Avoid long-term overcrowding disguised as a way to diffuse aggression. Observe after feeding, after maintenance and whenever the layout is moved, because each event can change which area is valued.

Related products shown elsewhere on the page are alternatives to consider, not a compatibility endorsement. A different cichlid may suit a keeper's aims better, but two individually appealing products should not be combined without a separate assessment. Compare adult size, water, territory and social behaviour for each animal on its own merits.

A simple decision rule

• Prefer: a species-focused setup or a generously sized, structured aquarium in which each fish has feeding access and room to retreat.
• Use caution: any pair or mixed arrangement, because territorial behaviour can change with maturity and spawning.
• Avoid: relying on small present size, colour, a single successful day or a generic tank-mate list as proof of long-term safety.
• Prepare: a humane separation plan before the fish is introduced, not after injury occurs.

The best compatibility outcome is not an aquarium that merely avoids fighting while someone is watching. It is one in which every animal continues to feed, rest, swim and use shelter normally over time. A jewel cichlid that owns one area while other fish retain the rest may be workable; one that patrols the full aquarium and excludes another fish is telling you the plan has failed.

Review the plan at predictable turning points

Compatibility is not decided once. Review it as the fish grows through its dispatch size, after major maintenance, when a pair begins to guard a surface and whenever a new animal is introduced. The important comparison is not whether chasing exists at all, but whether every fish can end an encounter, recover, feed and use shelter. Brief displays across a boundary carry different risk from repeated pursuit through the entire aquarium.

When separation is needed, move deliberately and protect water stability. The backup space should be mature enough to receive a live fish, heated appropriately and covered where necessary. Separation is not a failure; it is a normal welfare tool for an animal whose individual relationships cannot be guaranteed. The failed approach is recognising that a fish has lost access to the aquarium and leaving it there because the original combination looked attractive.

Questions before choosing this fish

How big does Rubricatochromis guttatus get?

FishBase records a maximum of 12.0 cm standard length for a male or unsexed fish. That is the adult biological record, while 3.5–5 cm and 5–7 cm are dispatch sizes. Individual growth and total length can differ, so plan for the recorded adult fish rather than the size arriving.

What size aquarium does this jewel cichlid need?

Plan the aquarium from FishBase's 12 cm standard-length record and its descriptions of aggression and the need for sufficient territorial space. Allow adult territory, cover, feeding access and a mature separation space. A generic litre figure cannot decide whether those needs are met for this fish.

How many Rubricatochromis guttatus should I keep together?

FishBase describes the species as pair-bonding, but this unsexed listing does not guarantee a compatible pair. One fish avoids pair conflict; two require close observation, ample cover and an immediate separation option. Do not assume that two juveniles will become a stable adult pair.

Is Rubricatochromis guttatus suitable for beginners?

It is better suited to an experienced keeper. The core filtration and maintenance are familiar freshwater tasks, but territorial aggression, adult planning and changing pair behaviour demand confident observation and a practical response when one fish loses space or feeding access.

What does this jewel cichlid eat?

FishBase records Rubricatochromis guttatus as omnivorous. Choose a complete food intended for omnivorous cichlids, use a particle size the supplied fish can take and follow the food manufacturer's directions. Watch that every fish feeds and remove leftovers rather than relying on an all-meat menu.

What temperature and pH suit Rubricatochromis guttatus?

Use a mature, biologically filtered aquarium with stable, measured conditions. The wild species record is habitat context, so do not turn its freshwater and brackish occurrences into a salt instruction or borrow a care range written for another cichlid group.

Is Rubricatochromis guttatus aggressive or likely to nip fins?

FishBase describes the species as aggressive and territorial. Chasing and injury risk can rise around a defended substrate or spawning site. The record centres aggression and territorial defence rather than a separate routine fin-nipping habit, so judge actual behaviour and act if another fish is excluded, damaged or unable to feed.

What kinds of animals can live with this jewel cichlid?

No universal tank mate is supported. Judge any proposed companion by whether both animals can retain feeding access, shelter and a route away from the defended territory as the cichlid matures. Keep a mature separation space ready and act if another fish is excluded, damaged or unable to feed.

How does Rubricatochromis guttatus arrive alive in the UK?

Tropical Fish Co hand-packs live fish in oxygen with insulation and a heat pack when weather calls for it, then uses a tracked licensed live-animal courier on the confirmed delivery day. Be present, record a continuous video from the sealed parcel before opening, inspect the fish that day and contact the store the same day if a Live Arrival Guarantee claim is needed.
