Also known as the Tanganyikan Clown, this is one of the so-called Tanganyikan goby cichlids. They occur only in the upper few feet of water around rocky shores, also known as the surge zone, where they scrape algae from the rocks with their specialised teeth. This habitat is typified by breaking waves and strong currents. They have a few adaptations allowing them to inhabit such an environment. The swim bladder is rendered useless to reduce their buoyancy. They also have a longand a laterally co...

An easily kept cichlid whose character more than compensates for its somewhat drab colouration, S. casuarius is sometimes seen for sale as "Humphead", "Lionhead" or "Buffalohead" cichlid. It is a reophilic fish meaning it inhabits fast waters. Its swimbladder is modified to reduce buoyancy and thus prevent it from being swept away by the strong currents in it's natural habitat. In the aquarium it spends most of it's time resting on the substrate or hiding ...

S. tinanti has a confused taxonomic history, having been previously classified in the genera Gobiochromis and then Leptotilapia, before being assigned to Steatocranus. Further taxonomic revision is likely, as it exhibits both behavioural and morphological differences to other species in the genus. It is a reophilic fish, meaning it inhabits fast waters. Its swimbladder is relatively small to reduce buoyancy and thus prevent it from being swept away by the strong currents in its natural habita...
