These fish are similar in their habits to the mbuna cichlids of Lake Malawi, feeding on algae growing on rocks around the lake’s perimeter. The many different morphs, which vary widely in appearance, are often named after the area of the lake in which they occur.
Kryptopterus bicirrhus (Asian Glass Catfish), is unusual in a number of ways. As its name implies, it is transparent and some internal organs and the skeleton can be seen. It is also one of the few catfishes that is not benthic (bottom-dwelling), remaining in mid-water. The body is compressed, similar to most other pelagic fishes, rather than depressed. They are shoaling catfishes that must be kept in small groups, not individually, otherwise they will not feed.
The water of the East African lakes is generally hard and alkaline, although actual conditions vary from lake to lake. Lake Victoria is only moderately hard with a neutral to slightly alkaline pH; water clarity is poor and quality unexceptional.
Qchlids (family Cichlidae) originate primarily in tropical America and Africa, with a few species in the Middle East and Asia. They are mainly freshwater fishes, though a few species require or tolerate brackish conditions. Size – adult Standard Length (SL) – ranges from 2 cm to 91 cm (3/4 in to 36 in) with a similar diversity in form, diet, and behaviour. Some species are very colourful and are thus attractive aquarium occupants. Many aquarists are, however, attracted by their interesting behaviour, character, and apparent intelligence; large specimens in particular can become genuine pets.
