Overview
A streamlined open-water predator built for speed, and one of the larger Malawi cichlids. It is solitary and aggressive, best kept singly or as one male with females in a very large tank, never with small fish. It patrols the open middle water chasing prey, so it needs length above all, and only big, robust tankmates that cannot be caught and swallowed. Feed meaty foods and expect a strong appetite. This fish needs the longest tank in the plan, 700 liters or more, with clear swimming room.
In the wild
Champsochromis caeruleus ranges through the open water of Lake Malawi, chasing schools of small fish across the lake. A tank for it should favor open space over decor, with a sand floor, minimal rockwork set low, and long uninterrupted swimming lanes. Keep the water hard and alkaline like the lake, warm at 24 to 27 C with a pH of 7.5 to 8.5, and use powerful filtration and good flow for a large, active swimmer.
Good to know
This species belongs to the Cichlidae and reaches about 32 centimeters, iridescent blue over a slim, trout-like body. Its genus name Champsochromis is built from the Greek for crocodile, a nod to its predatory snout, while the species name caeruleus is simply Latin for blue. It is a maternal mouthbrooder, and breeding it is hard. In the wild it is a pursuit predator that feeds largely on the small Malawi sardine.
Did you know
Its genus name means crocodile cichlid while its common name calls it a trout, two very different hunters borrowed for one fish. What both capture is the point: a fast, streamlined body made for running prey down in open water.
