Calculate heater sizeCare Notes
- Give them space: plan on at least an 80-gallon tank with heavy hardscape and multiple caves to break sight lines; this species throws attitude, especially as a pair.
- Hold water at 24-26 C, pH 6-8, and 5-12 dGH, and avoid quick parameter swings.
- Feed a varied omnivore diet: quality pellets or flake as the staple, plus frozen or live foods like bloodworms and brine shrimp for condition and color.
- Tankmates should be chosen carefully; skip other cave-spawning cichlids or similarly shaped bottom fish, and give any companions room and cover.
- They are pair-bonding cave spawners; offer several snug caves and expect intense territorial defense when eggs or fry are present.
- At up to 12.5 cm TL and chunkier than the common krib, they need substantial territory; do not try to cram more than a pair into tight quarters.
- Lifespan is 5-8 years with steady care, so set them up to succeed long term rather than treating them like a small community krib.
Compatibility
Good Tankmates
- Robust, fast midwater West African characins kept in sizable shoals (e.g., Congo tetras, African red-eye tetras, Brycinus spp.); they stay off the bottom and help diffuse cichlid aggression.
- Armored Synodontis catfish of modest size (e.g., upside-down catfish Synodontis nigriventris); tough, nocturnal bottom helpers that usually avoid krib caves if given their own wood and hides.
- Bristlenose pleco (Ancistrus) or similar small loricariids; armored algae-grazers that ignore the kribs if their retreat spots are separate from the kribs' spawning caves.
- Non-nippy, medium alestids/barbs with some body mass (e.g., African banded barb Enteromius fasciolatus) kept in a group; active midwater fish too quick to be singled out.
- Medium-large rainbowfish (Melanotaenia/Glossolepis) in a roomy, well-structured tank; fast open-water swimmers that handle neutral water and draw focus away from the bottom.
Avoid
- Other cave-spawning cichlids or additional krib/Wallaceochromis/Pelvicachromis pairs; heavy territorial overlap leads to persistent fights, especially in breeding season.
- Bottom-foraging fish that wander into caves (Corydoras, kuhli loaches, small loaches); they get chased and can be injured when the kribs guard eggs or fry.
- Delicate or slow, long-finned fish (angelfish, fancy bettas, many gouramis); prone to harassment and fin damage.
- Dwarf shrimp and tiny nano fish; likely to be hunted or picked off around the substrate and plants.
Yellow kribensis (Wallaceochromis humilis) is a West African cichlid that grows chunkier than the common krib and shows bold breeding colors, especially in locality forms like Liberia Red. It is a pair-bonding cave spawner with real attitude. Adults reach about 12.5 cm TL, live 5-8 years, and demand space and structure.
Origin and natural habitat
This freshwater species comes from West Africa, in coastal drainages from Guinea to Liberia. In nature it uses cover and cavities and is adapted to structured, sheltered margins of rivers and streams. That background informs how you should scape the aquarium: plenty of hiding places, broken lines of sight, and secure caves.
Aquarium setup and water
Minimum tank size: 80 US gallons. This fish is semi-aggressive and territorial, especially as a pair. It needs room and structure to keep the peace.
- Aquascape: Provide multiple caves (rock piles, ceramic tubes, snug wood crevices), driftwood, and hardscape to break sightlines. A sand or fine gravel substrate lets them dig around their chosen site.
- Filtration and flow: Moderate filtration with gentle to moderate flow. Keep the water well-oxygenated without blasting their caves.
- Lighting: Moderate to subdued lighting helps them feel secure; floating cover or overhanging hardscape works well.
- Maintenance: Regular, steady water changes and stable parameters are more important than chasing extremes.
- Temperature: 24-26 C
- pH: 6-8
- Hardness: 5-12 dGH
Diet and feeding
An omnivore. Offer quality cichlid pellets or flake as a staple, backed up with frozen or live foods such as bloodworms and brine shrimp. Rotate items for variety. Small, regular feedings are better than heavy meals, which can foul the water.
Behaviour and tankmates
Yellow kribensis is semi-aggressive and strongly territorial, especially as a bonded pair around a cave. The extra footprint of a large tank and lots of cover make a big difference.
- Best kept as a single mature pair. Keeping multiple pairs or similar cichlids together takes very large space and carefully divided territories.
- Choose robust, alert tankmates that use other areas of the tank. Avoid slow or long-finned fish that cannot handle bursts of aggression.
- Add visual barriers so subdominant fish can get out of sight quickly.
Expect an aggression spike during courtship and spawning. Tankmates should be able to retreat, or consider a dedicated species setup.
Breeding
This species is a pair-bonding cave spawner. A bonded pair will select a tight cave, clean the inside, and defend the surrounding territory. Both parents guard eggs and brood, then herd free-swimming fry.
- Provide several cave options of different sizes and orientations so the pair can choose.
- Keep water stable within the ranges above and minimize disturbance near the spawning site.
- Once fry are free-swimming, offer very small foods such as newly hatched brine shrimp and finely powdered fry diets.
Common pitfalls
- Cramped quarters: Crowding a territorial pair in a small or sparsely scaped tank often leads to injuries.
- Sparse hardscape: Without caves and broken sightlines, aggression concentrates on tankmates with nowhere to go.
- Unstable water: Sudden swings in temperature or chemistry stress this species; keep parameters steady within the stated ranges.
- Overfeeding rich foods: Heavy portions of frozen or live foods pollute the water quickly; keep portions modest.

American flagfish
Jordanella floridae
Jordanella floridae is that little Florida native with the red-and-cream striping that really does look like a tiny flag once a male colors up. They graze algae like champs (especially stringy/hair algae), but they have a bit of attitude - give them plants and space so the bossy behavior stays manageable. Bonus: the male guards the eggs and will actively fan them, which is pretty fun to watch.
Banded Leporinus
Leporinus fasciatus
Banded Leporinus are those torpedo-shaped, black-and-yellow striped fish that look like they're wearing a little prison outfit-and they stay on the move. They've got a ton of personality and they're awesome to watch cruising and picking at stuff, but they're also the kind of fish that will redecorate your tank and "taste test" anything soft-looking.
Bandi cichlid
Wallaceochromis signatus
A West African dwarf cichlid from Guinea's Bandi River, this fish shows crisp vertical bars and spotted fins with red highlights. Females have a bold black spot at the base of the tail, and pairs guard eggs and fry in caves, which makes their parental behavior fun to watch.
Betta
Betta splendens
Betta fish, also known as Siamese fighting fish, are popular for their striking colors and flowing fins. They are known for their territorial nature, especially males, which can display aggressive behavior towards each other.
Blackhawk catfish
Wallagonia micropogon
Wallagonia micropogon is a giant Southeast Asian sheatfish with an eel-like body and a huge, scoop-like mouth for hunting other fish. It is native to the Mekong and middle Chao Phraya basins and was long confused with Wallagonia leerii, which makes IDs and care notes tricky. Stunning as a juvenile but it grows to true megafish size, so it is only realistic for expert keepers or public aquariums.
Boulenger's Featherfin Tetra
Bryconaethiops boulengeri
A big, fast African tetra from the Congo River basin, it cruises the mid-to-upper water in active groups and flashes a bold broken stripe along its flanks. In the wild it hunts insects at the surface and can leap, so aquariums need tight lids. Keep it with robust tankmates it cannot swallow.

Amapa tetra
Hyphessobrycon amapaensis
This is a tiny, super sleek little tetra with a clean red stripe down the side that really pops once its settled in. It does best in a planted, slightly tinted "creek-style" setup and looks way cooler when you keep a proper group so they school and flash that line together. If you can give it soft, slightly acidic water and a calm community, its an easy fish to fall for.
Armoured stickleback
Indostomus paradoxus
This is that goofy little "freshwater seahorse"-looking fish that just kind of perches and scoots around like a tiny armored twig. Its whole vibe is slow, sneaky micropredator - once its settled in, you will catch it stalking microfoods and doing these subtle little posture displays. The big trick is feeding: they do best when you can provide lots of small live foods in a calm, planted tank.
Arrowhead puffer
Pao suvattii
Pao suvattii is that sneaky Mekong puffer that likes to sit low and ambush food, and it has that super recognizable arrow/V pattern on its back. Gorgeous fish with tons of personality, but it is absolutely not a community guy - plan on a solo, species-only setup if you want everybody to stay in one piece.
Bishop toothcarp
Brachyrhaphis episcopi
This is a tiny Panamanian livebearer that does best when you treat it more like a shy wild fish than a fancy guppy-lots of cover, calm vibes, and really clean water. The fun part is watching the males posture and spar while the females cruise around dropping fully-formed fry about once a month.
Black morpho tetra
Poecilocharax weitzmani
Poecilocharax weitzmani is one of those tiny blackwater oddballs that acts more like a little darter than a typical tetra - it hangs low, darts between cover, and the males can get pretty showy with fin-flares. The really cool part is they are cave breeders with male brood care, which is not what most people expect from a small characin. Give them very soft, acidic, super-clean water and lots of leaf litter and hidey holes, and they settle in and start showing their best colors.
Black Neon Tetra
Hyphessobrycon herbertaxelrodi
Black neons are one of those little tetras that look kinda understated until the light hits them-then that bright stripe pops and they shimmer when the school turns together. They're super chill, always cruising mid-water, and they make a tank feel "alive" without being hectic. If you keep a nice group, they get bolder and you'll see way more of their personality.
