Care at a glance

Species-specific aquarium care

  • Tank: At least 24 in long and 12 in front to back for one adult (adults commonly reach about 4.0 in / 10.2 cm).
  • Water: Freshwater.
  • Temperature: 77–79°F (range recorded for this species).
  • Layout: Uses both the bottom and open water: give open swimming space plus cover near the substrate.
  • Availability: Rarely or never seen in the aquarium trade; expect to source it from specialists or not at all.

Calculated from this species' own FishBase record: tank size from its typical adult length and swimming zone, water values from its recorded ranges. The group guide below fills in general care.

Care guide

Species care notes

  • Tank: a base of at least 47 × 12 in (roughly 43 US gallons); space needed is rated “large tank”.
  • Water: a fairly wide range, from slightly acidic to slightly alkaline, 72–81 °F, pH 6.5–7.5, 5–15 dGH.
  • Behaviour: temperament territorial.
  • Difficulty: Moderate (Seriously Fish rating).

Short excerpts from the species profile:

  • Setup: “As mentioned above, the aquarium should have as large a 'footprint' as possible.”
  • Tankmates: “A territorial species that is generally peaceful towards heterospecifics.”

Group care guide

West, Central and southern African river cichlids and tilapias

Applies to most species in this group. Habitat: African rivers, streams and lakes. Individual species can differ, so compare with the species numbers above and the linked sources.

Housing & setup

  • Kribensis and other dwarf West Africans do well in planted 20–30 gallon tanks with caves and neutral water.
  • Tilapias and Serranochromis grow large and are often kept in ponds or for aquaculture.

Sources 117119164

Diet

  • Omnivorous pellets plus frozen foods; tilapias need plant matter.

Health watch

  • Several tilapias are invasive and regulated by many states; never release.

Understanding the animal

This species is part of a group that hobbyists, aviculturists or zoos keep widely (Cichlids), so it's included for completeness. It may be rare in captivity itself, or not kept at all. Use the group guide as a starting point and look for species-specific advice from experienced keepers.
No real photograph of this species is freely available yet. The only images we found were scientific illustrations or maps, so none is shown. It stays on the site because there is evidence it is kept (see “Kept in captivity?”), but it is rarely kept or rarely photographed. If you keep one and can share a photo, we would love to add it.
About this animal

About this animal

It has also been reported from Pool Malebo (Stanley Pool) and the Regina Falls in the lower Congo River basin, but the identity of these populations requires further investigation. This species can reach a length of 10.2 centimetres (4.0 in) SL. The specific name honors the Belgian Army Lieutenant Maurice Joseph Auguste Marie Raphael Storms (1875-1941) who collected the type which he presented to the Brussels Museum.
