Cichlids are a family of roughly 1,800 accepted species, not one care type. Before buying, identify the exact species and source, then compare adult measurement, usable tank dimensions, social system, territory, tested water, diet and an exit plan. No family-wide minimum tank, water range or tank-mate list is safe.

The Electric Yellow Cichlid Kakusa (Labidochromis sp. Kakusa) is a Lake Malawi cichlid in the family Cichlidae, native to East Africa. It suits a keeper prepared to build a hard, alkaline and strongly filtered Malawi aquarium rather than a peaceful mixed community. Its vivid trade identity makes it visually distinctive, while its care must account for the aggression associated with Malawi cichlids.
WoRMS recognises Labidochromis as an accepted cichlid genus. Wikipedia describes the genus as endemic to Lake Malawi and notes that it contains formally described and undescribed species. That genus identity matters when planning its aquarium: treat Kakusa as an unidentified Labidochromis, not as a named species with a fixed adult length.
This form can suit a first-time Malawi keeper who is ready to manage specialised water chemistry, strong filtration and an aggressive community. OATA describes Malawi cichlids as usually undemanding and easy to keep, but also warns that they are aggressive and must be mixed cautiously. Success therefore depends less on advanced equipment than on making disciplined decisions about water, space, stocking and maintenance.
Start with the complete community plan rather than choosing one bright fish at a time. Decide which Malawi cichlids will share the aquarium, how the group will be introduced and whether the filter can support the intended biological load. Use our African cichlid collection to compare identities, then apply the compatibility rules below before combining any animals.
One purchase supplies one Electric Yellow Cichlid Kakusa in the size chosen on the live selector. The named choices are 3–4 cm, 4–5 cm and 6–7 cm. These labels describe the fish’s dispatch length and let you choose the appropriate supplied grade for your stocking plan. The size you select is the size supplied, not the adult size.
The exact species has not been identified, so the care advice here follows the genus Labidochromis and its care group. Plan the aquarium around the demands of a Malawi community and allow for growth without assigning this fish the adult length of a different named species.
Sex is guaranteed only when the selected option explicitly states male or female. This Electric Yellow Cichlid Kakusa listing has no sex-guaranteed option. Do not build a male-to-female stocking ratio around colour, current length or a gallery image. OATA notes that many Malawi cichlids show sex differences only when adult, so any later ratio adjustment should follow reliably established sex rather than an early visual guess.
The gallery images are representative of this type of animal rather than photographs of the exact animal supplied, so colours can look slightly different from the live animal. The pictured fish shows the bright yellow body and subtle dark dorsal edging associated with the trade form, but the scene does not determine the sex, age or final appearance of the fish selected.
Keep this fish at 23–27°C, pH 8.0–8.6 and 12–18°dH in a mature Malawi aquarium. For a reasonable-sized community, plan at least 200 litres, an oversized filter and strong aeration. OATA says Malawi cichlids can be kept in groups of at least 15 and that small groups often fight, so the whole stocking plan must be assessed before fish are added.
| Suits | Not suited to |
|---|---|
| A hard, alkaline Malawi aquarium | A soft-water community |
| A planned group with at least 200 litres | A small or casually assembled group |
| Oversized filtration and strong aeration | An unfiltered or newly established aquarium |
| Other screened Malawi cichlids or some screened Synodontis | Fish outside those OATA companion categories |
| An aquarium containing one Labidochromis species | Mixing multiple Labidochromis species |
The 200-litre figure is a community recommendation, not a personal territory allowance for one fish. A workable plan combines water volume, filtration capacity, oxygenation, décor and the behaviour of every intended animal. Do not treat one favourable number as permission to overlook the others.
Easy routine care does not mean unrestricted compatibility. The keeper still needs to maintain zero ammonia and nitrite, manage nitrate, feed measured portions and respond promptly to changes in aggression or condition.
Keep the aquarium at 23–27°C, pH 8.0–8.6 and a general hardness of 12–18°dH. Carbonate hardness should be 10–15°dKH. OATA’s African Malawi cichlid guidance gives these values for the group; use them as broad community planning values for this unidentified form.
Ammonia and nitrite must remain at zero milligrams per litre. Nitrate must not exceed 20 milligrams per litre above the normal tap-water level. A stable pH does not compensate for ammonia or nitrite, and clear-looking water does not show whether either compound is present. Test the values rather than judging water by appearance.
Use the same units each time so results remain comparable. Our water chemistry guide explains what the principal readings mean, while the water matcher helps compare measured aquarium water with the stated range. Record temperature, pH and nitrogen-waste results together; a trend across several tests is more useful than an isolated reading.
Avoid chasing readings with repeated abrupt changes. Prepare replacement water consistently and test again after corrective maintenance so the next decision is based on a measured result.
Plan at least 200 litres for a reasonable-sized Malawi cichlid community. OATA recommends choosing as large an aquarium as reasonably possible because greater water volume makes temperature and water quality more stable. Use that figure for the planned community rather than treating it as a species-specific minimum for one unidentified Labidochromis.
Malawi cichlids are not social fish, but OATA says they can be kept in groups of at least 15 and slightly overcrowded to limit aggression. Small groups often fight. This approach creates a substantial biological load, so it is only suitable when aquarium volume, oversized filtration, aeration and maintenance can support the complete group.
Work from the intended mature community, even though the chosen fish arrives at a smaller dispatch length. Do not start with a small aquarium on the assumption that a young fish can be moved later. The aquarium must support the behavioural and water-quality demands of the planned group from the beginning.
Provide coral sand or a similar substrate that helps buffer the water. Malawi cichlids often dig and rearrange substrate, so secure the layout against that behaviour. OATA distinguishes rock-dwelling mbuna from open-water utaka; this Kakusa form is placed in the mbuna trade group, making a rock-oriented community layout the appropriate starting point.
Decorative choices never replace adequate volume or compatible stocking. Rockwork can interrupt encounters and create territories, but every animal still has to fit the same Malawi water and community rules.
Use an oversized filter and strong aeration for the intended Malawi community. OATA recommends both because the group-management approach creates crowded conditions and a high demand for dissolved oxygen. Check that flow reaches the aquarium effectively and that the filter is accessible for regular blockage checks.
The RSPCA explains why biological filtration is essential: fish release toxic ammonia, beneficial bacteria convert it to nitrite and then to the safer nitrate. A filter is therefore life-support equipment rather than an optional way to make the aquarium look clean.
Mature the aquarium and biological filter before livestock is added. Our first tropical aquarium guide covers preparation and maturation. Readiness is shown by water testing: ammonia and nitrite must both be zero before the fish enters the aquarium.
Increase the number of fish slowly. OATA warns that beneficial bacteria need to increase whenever more fish are added and feeding rises. Adding too much livestock too quickly can create new tank syndrome, in which the filter cannot process the increased waste and ammonia or nitrite reaches harmful levels.
| Checkpoint | Decision |
|---|---|
| Before the first fish | Confirm zero ammonia and zero nitrite. |
| After a stocking increase | Test for a rise in ammonia or nitrite before adding more. |
| During each weekly check | Inspect flow, aeration and the filter for blockages. |
| If fish breathe differently | Test water and check oxygenation immediately. |
Do not use calendar age alone to declare an aquarium mature. The practical question is whether the working filter can process the waste created by its present population while the required readings remain stable.
At least once every week, change 25% of the aquarium water. Use a siphon to remove solid waste from the substrate where practical. The frequency applies to the water change: it does not turn 25% into a minimum volume to increase without considering the aquarium’s stability.
Test ammonia and nitrite at least once per week and keep both at zero. Monitor nitrate against OATA’s limit of no more than 20 milligrams per litre above the normal tap-water level. Testing before the routine change can show what accumulated during the week; testing again after a concerning result confirms whether the corrective work succeeded.
Treat replacement tap water with a conditioner that removes harmful chlorine or chloramine before adding it to the aquarium. Prepare it consistently so routine maintenance does not produce a sudden avoidable shift. Check temperature and relevant chemistry whenever the source water or aquarium readings have changed.
Check the filter for blockages. When cleaning is needed, do not run the filter media under the tap. Rinse it lightly in aquarium water removed during the partial water change; this reduces the number of beneficial bacteria lost during cleaning.
Record each maintenance date and its test results. A simple log shows whether the aquarium remains stable as fish grow or the community changes, and it makes a gradual loss of filter performance easier to notice.
Feed twice a day, giving only what the fish can eat within a few minutes. Remove or account for uneaten food and reduce the next portion if food remains after that interval. OATA warns that overfeeding allows waste food to break down and release toxic material into the water.
Use a specialised Malawi cichlid food with a high algae content as the staple for this mbuna trade form, and add suitable fresh vegetable matter for variety. This follows OATA’s guidance for smaller mbuna while avoiding a species diet claim for an unidentified Labidochromis.
Keep portions small enough that every meal is completed promptly. “Twice a day” does not mean two large feeds, and a fish approaching the food is not a reason to keep adding more after the timed portion has been eaten.
| What you see | What to do |
|---|---|
| Food remains after a few minutes | Reduce the amount at the next meal. |
| Food accumulates in the substrate | Remove the waste and review both portion size and delivery method. |
| Interest in food falls | Test water quality and check for other changes in condition or behaviour. |
| A fish is excluded by aggression | Review the stocking arrangement instead of adding excess food. |
Diet variety should remain within the Malawi mbuna approach rather than becoming a sequence of rich treats. Keep the staple consistent, introduce any change gradually and monitor both appetite and waste. The useful measure is whether the complete group eats the offered portion within a few minutes while ammonia, nitrite and nitrate remain controlled.
Prepare the mature aquarium and confirm its water readings before the parcel arrives. The fish is hand-bagged in pure oxygen and placed in an insulated poly box, with a heat pack when the weather calls for one. A licensed live-animal courier carries the parcel, and someone must be present to receive it.
The continuous video is part of the Live Arrival Guarantee claim process and should begin before the parcel is opened, not after the fish has been removed. Keep the sealed bag in view long enough for its condition to be seen before proceeding with release.
Read the current delivery and Live Arrival Guarantee policy before the arrival day. It contains the packing, receipt, acclimatisation and claim requirements that apply to the order.
The parcel procedure does not replace aquarium preparation. Confirm zero ammonia and nitrite, a temperature of 23–27°C and pH of 8.0–8.6 independently. If those values are wrong, correct the aquarium plan before the delivery rather than trying to solve a water-quality problem while the fish is waiting in its bag.
Use the fish’s normal appearance, swimming, breathing, temperament and appetite as the daily baseline. OATA recommends watching for changes because early differences can reveal a developing problem before it becomes severe.
If any of these changes appear, test ammonia, nitrite, nitrate, pH and temperature. Confirm filter flow and aeration as part of the same check. A behaviour change can coincide with aggression, but it can also affect several fish when water quality has deteriorated; testing separates those immediate decisions.
| Pattern | First response |
|---|---|
| Several fish breathe abnormally | Test water and check aeration immediately. |
| One fish hides after chasing | Review compatibility, territories and stocking. |
| Appetite drops across the group | Test water and inspect the filter before the next feed. |
| Visible spots, growths or tissue loss | Record the signs and seek case-specific guidance. |
Do not select a treatment from one vague symptom. If livestock health remains concerning after the immediate water and equipment checks, contact us for further guidance with the measured results and a clear description of the change.
Keep this fish only with other Malawi cichlids or some species of Synodontis catfish. OATA gives those as the companion categories for Malawi cichlids; “some” does not mean every Synodontis is suitable. Avoid fish outside those categories rather than trying them after a superficial water match.
A “yes” to water chemistry alone is not enough. Malawi cichlids are aggressive, and OATA advises mixing them with caution. The answer depends on the complete set of fish, the aquarium and the order in which animals are introduced, not on a universal tank-mate label.
Add Malawi cichlids in groups so one new individual does not receive all the aggression while settling. Introduce more peaceful species before more aggressive species. OATA also advises that rearranging aquarium décor can reduce aggression as fish establish new territories.
Ask us to assess the full stocking list before combining named animals. Include aquarium volume, present livestock, intended additions and current water readings. This assessment is especially important for Synodontis, because the companion guidance permits only some species rather than the whole genus.
Do not use current dispatch length as a compatibility guarantee. No rule here establishes that two fish become compatible because they arrive at similar sizes. Base the decision on the companion categories OATA names, shared water requirements and the behaviour of the planned community.
Keep only one Labidochromis species in the aquarium. Wikipedia notes that members of this genus can hybridise easily and recommends keeping a single species from the genus. That makes another Labidochromis an animal to avoid in this Kakusa aquarium, even if its water requirements appear similar.
OATA says Malawi cichlids can be kept in groups of at least 15 and slightly overcrowded to spread aggression, while small groups often fight. This is permission for a carefully filtered community strategy, not a direction to exceed the aquarium’s biological capacity. The oversized filter, strong aeration and weekly maintenance must be planned for the resulting load.
Where reliably established sexes are known, OATA advises keeping more females than males of each species to reduce persistent male attention towards one female. Many Malawi cichlids only show sex differences when adult. Do not alter the stocking plan from colour or size guesses.
| What you see | What to review |
|---|---|
| Repeated chasing of one fish | Group composition, introduction order and territories. |
| A fish hiding more than normal | Aggression, water quality and access to the aquarium space. |
| Damaged fins or missing scales | Immediate separation needs and the compatibility plan. |
| Aggression after an addition | Whether fish were introduced as a group and whether décor should be rearranged. |
Do not describe this cichlid as peaceful because it appears calm during one observation. The correct baseline is an aggressive Malawi fish that requires active management. Changes in aggression should also trigger a water test, because poor water conditions can add stress to an already demanding social environment.
The exact adult length depends on which Labidochromis species this Kakusa form represents, so plan its home as an unidentified Labidochromis and use OATA’s at-least-200-litre recommendation for a reasonable-sized Malawi community.
For a reasonable-sized Malawi community, OATA recommends an aquarium of at least 200 litres, with an oversized filter and strong aeration.
OATA says Malawi cichlids can be kept in groups of at least 15 and that small groups often fight; assess the complete group against aquarium and filter capacity.
It can suit a beginner prepared for hard alkaline water, aggressive behaviour and disciplined maintenance; OATA describes Malawi cichlids as usually undemanding and easy to keep.
Feed specialised high-algae Malawi cichlid food and suitable fresh vegetables twice daily, offering only what it can eat within a few minutes.
OATA’s Malawi group guidance gives 23–27°C, pH 8.0–8.6 and hard water of 12–18°dH.
OATA describes Malawi cichlids as aggressive, so inspect fins and behaviour daily and act on repeated chasing, hiding or physical damage.
Keep it only with screened Malawi cichlids or some screened Synodontis species, and avoid keeping another Labidochromis species because the genus can hybridise easily.
The Tropical Fish Co delivery policy says it is hand-bagged in pure oxygen, insulated and carried by a licensed live-animal courier. Receive it in person, film the sealed-parcel opening continuously and float the bag for 20–30 minutes before release.

What customers say about ordering from us
I have a small group of long finned mountain minnows. So was delighted to be able to order ten of this variety to increase the genetics in my tank . The ones I recieved are healthy but it’s to early to give a verdict on wether they are of a long finned type since they are small currently.
