Prior to the description of C. gibberosa in 2003 the genus Cyphotilapia was considered monotypic for almost a century. Members are separated from other cichlid taxa inhabiting Lake Tanganyika by possession of a hump on the forehead and broad vertical bands on the body, although the latter tend not to be visible in large males.

Despite being a wholly unsuitable aquarium subject, C. idella is often traded as such, with an albino form having been developed specifically for the ornamental market.

Individuals which have outgrown their aquarium or pond should never be released into natural waters, either, since this species has proven capable of causing serious environmental damage under a wide range of climatic conditions.

This undescribed species is also traded as C. sp. 'ndoboi' or 'ndobnoi', and despite its lack of official recognition it's the most commonly-encountered member of the genus in the aquarium trade at time of writing. It can be easily-distinguished from the congeners C. brichardi and C. popelini by its adult body patterning which comprises two or three series of irregular, dark, laterally-orientated blotches, the upper of which is often contained entirely within the dorsal …

Butis spp. are largely nocturnal ambush predators with cryptic patterning to help them blend in with their surroundings. They can also lighten and darken their body colouration to an extent, have a habit of aligning themselves with solid surfaces whether horizontal, vertical, or inverted, and often swim in an upside-down position.

The genus is usually included in the family Eleotridae of which members are often referred to…

Endemic to Lake Victoria which has a shoreline divided between Kenya, Uganda and Tanzania, although P. nyererei has been recorded only in the southern part of the lake belonging entirely to Tanzania.

Type locality is ‘Mwanza Gulf, Tanzania, Lake Vic…

This cichlid is a true wonder of nature. It lives in a soda lake which is full of hot, alkaline springs. The water contains a high concentration of sodium carbonate and other dissolved minerals and salts. The water conditions in the lake are typically pH 9.5-10.5, kH 7000+ and temperature 90-110°F! The water also has a sg reading of 1.2+ and is very shallow, having a maximum depth of only 2 metres. The fish can be acclimatised to more 'normal' conditions but the pH should not be al…

Deservedly one of the most popular Tanganyikan species available in the hobby, N. brichardi is ideal for newcomers to both Rift Lake cichlids and cichlids in general, being beautiful and easy to keep and breed. It is seen for sale under several common names including "Fairy Cichlid", "Lyretail Cichlid" and "Princess of Burundi". There are several colour morphs available, although these do not vary much in patterning, and an albino form is also occasionally available…

Mostly inhabits littoral to sublittoral zones, habitats which normally comprise a mixture of rocky rubble and exposed sandy areas, but has been recorded to depths of around 100 m. When not breeding adults exhibit a more-or-less pelagic lifestyle and apparently tends to form small, foraging groups in open water, whereas juveniles inhabit shallower, sandy nursery zones with some rock cover. There exists some evidence to suggest that adults move inshore at night or during early morning in order to feed.

Males of this species occur in a wide range of colour forms depending on locality, with blue variants being found predominantly (but not exclusively) towards the north of the lake and yellow in the south. This variation, alongside its relatively extensive distribution, has resulted in some taxonomical issues, several of which have not yet been resolved.

For example, two forms from the southwest of the lake are referred to as A. sp. “stuartgranti maleri” and A. sp. “stuartgranti mbenji”, respectively, and may turn out to be distinct species given their colour patterns an…

This was one of the first Aulonocara spp. to enter the hobby and its popularity has endured. It’s known by several other vernacular names including ‘Freiberg’s peacock’, ‘fairy cichlid’ and ‘African butterfly’ as well as the erroneous ‘scientific’ names Trematocranus trevori, T. jacobfreigbergi and T. regina. A naturally-occurring, yellowish form from Undu reef, Tanzania is often referred to as ‘lemon jake’.

It can be told apart from most other members of the genus by the broad, pale distal margins in the dorsal, anal and caudal fins, more deeply-forked caudal fin and larger adult size.
