The Proteus pike cichlid, Saxatilia proteus, is one of the smaller pike cichlids, known from Ecuador, Peru and Brazil. It is occasionally offered for sale and more than makes up for its size in aggression, especially towards conspecifics. It will eat any fish small enough to be considered food, so suits a tank of larger cichlids or a species-only set-up.

Distribution

Ecuador, Peru and Brazil. In Ecuador it's known from the Rio Napo and Rio Putumayo. In Peru it's range extends from the Rio Ucayali to the Rio Pebas. Populations have also been recorded from the Rio Purus in Brazil.

Habitat

Well planted shallows.

Maintenance

Sand substrate is recommended. This species is likely to dig and arrange the decor to suit itself. Some rockwork should be provided to form caves as pikes like to have an area to which they can retreat. Plants should be robust, ideally potted or rooted to bogwood.
