Striped kribensis
A smaller and more colourful relative of the common kribensis, sold as several regional forms. Like its congener it is a cave spawner, and like it the peaceful reputation ends when a pair spawns.

Name ambiguity
Sold as a series of regional forms — Nigeria Red, Moliwe, Wouri and others — which differ markedly in colour and are all traded under this name.
Adult size and growth
6–9 cm (2.4–3.5 in)
Typical lifespan in an aquarium: 5–8 years. Almost every animal sold in a shop is a juvenile, so the tank has to suit the size in the first line rather than the size in the bag.
Water and tank requirements
Floor area and caves. A spawning pair defends ground, and the tank has to contain somewhere outside it.
| Requirement | Value | Notes |
|---|---|---|
| Temperature | 24–27 °C (75–81 °F) | Stability matters more than hitting an exact figure. |
| pH | 5.5–7.5 | A stable pH outside the ideal band is usually better than an unstable one inside it. |
| General hardness | 2–12 °dGH | Check your supplier's published figure before choosing species. |
| Minimum volume | 90 L (24 US gal) | A floor, not a recommendation. |
| Minimum footprint | 75 cm long × 35 cm deep | Floor area and caves. A spawning pair defends ground, and the tank has to contain somewhere outside it. |
| Water flow | moderate | Match the outflow to this rather than to the filter's rating. |
| Lid required | Recommended | Reduces evaporation and prevents accidents. |
| Structure | Caves, shaded planting and soft substrate. |
Behaviour
- Holds a cave and the ground around it; the female leads the display.
Telling males from females
Females are smaller with a vivid purple-red belly when in condition; males are larger with extended finnage.
Feeding
- Diet type
- Omnivore
- Staples
- Sinking pellets, Frozen bloodworm and daphnia, Vegetable matter
Breeding
- Strategy
- Cave-spawning with both parents guarding
- Difficulty
- straightforward
- Parental care
- guarding
Brood sex ratio in this genus is strongly pH-influenced, so water chemistry has consequences beyond comfort.
Tankmates and compatibility
Assessments are derived from stored traits by the compatibility engine, with the reasoning shown. A verdict is a statement about probability, not a guarantee — individual temperament can override it.
| Towards | Risk | What it means |
|---|---|---|
| Small fish | moderate | Anything that fits in the mouth is at risk once this species reaches adult size. |
| Adult dwarf shrimp | high | Cover reduces losses but rarely prevents them where the risk is high. |
| Shrimplets | high | Determines whether a shrimp colony can grow rather than merely persist. |
| Snails | low | Applies to snails you wanted as well as snails you did not. |
| Long or trailing fins | occasional | Fin damage is an entry point for secondary infection. |
| Plants | uproots | Tough species such as Anubias and Java fern survive most grazers. |
Any pair in the catalogue can be assessed with the compatibility checker.
Welfare considerations
Points where the way this species is commonly sold or kept differs from what it actually needs.
- Regional forms are sold interchangeably and may not be the same species.
Problems to watch for
Most problems in a tank containing this species are general rather than species-specific. Start with the troubleshooting index and work from the observation rather than from a guess at the cause.
What AquariumHQ does not yet hold
Species-level disease susceptibility is modelled in the graph and is not yet populated. Health pages will not be published until each condition has veterinary sourcing, because health content written without evidence is the most harmful thing this product could publish. The gap is recorded in the coverage report.
Where it comes from
- Native range
- Coastal southern Nigeria and western Cameroon
- Habitat
- Small, shaded forest streams, soft and slightly acidic.
What the checklists say
2 distribution statements retrieved from GBIF checklists. Establishment means is reproduced from the source where it states one, and left unstated where it does not — a record of presence is not a record of origin.
| Status | Places | What this means |
|---|---|---|
| Recorded as present, establishment means not stated | 2 | The source records the species as present and does not say whether it is native or introduced. AquariumHQ does not fill that in. |
No checklist AquariumHQ holds positively calls this species native anywhere, so the native range above rests on AquariumHQ’s own reading of the literature rather than on a cited checklist.
Evidence
Every stored value with the kind of support behind it and where to check it. Evidence type and confidence are separate axes: an editorial position held confidently and a measurement held tentatively are different things.

Why we say this
What each figure on this page rests on, and how far that is from being independently established.
Every figure on this page has a provenance. Open any claim to see what AquariumHQ holds for it, which sources say what, and what a claim of that kind actually needs. Different claims need different evidence: an accepted scientific name is settled by one authority, while a legal restriction needs a current primary instrument. A single source is often the right answer rather than a thin one.

What this kind of claim needs: accepted scientific name and classification — 1 authoritative source in an appropriate context. Checked against gbif on 2026-08-11. One authoritative backbone is what this class requires.

AquariumHQ's own position on a claim an external source could support.
What this kind of claim needs: where the species occurs — 1 authoritative source in an appropriate context. 2 distribution statements held, and not one of them states an establishment means. Presence without native-or-introduced is not a native-range claim, so this stays below requirement rather than being read as one.

Group size and social behaviour
Forms strong pairs. A spawning pair holds territory and drives off anything entering it, including much larger fish.
