Overview
The Tuba cichlid is a big, current-loving cichlid for a river-style tank. It suits a keeper with some experience.
Did you know
The Tuba cichlid is a true river fish, unlike most of its large Central American relatives. Those cousins favor still or slow water.
Caring for the Tuba cichlid
Give a Tuba cichlid at least 119 gal (450 L), since this big, active fish needs real volume. Provide strong, steady current from oversized filters or a flow pump, with rounded boulders and a firm floor. Keep the tank well oxygenated, because it needs high oxygen to stay healthy.
Hold the water warm and neutral to slightly hard, at 75 to 84°F (24 to 29°C) and a pH of 7.0 to 8.2. It stays low, grazing surfaces and picking at the bottom. In flowing water it eats the algae and small animals that grow on rock. Feed a mixed diet with plenty of vegetable matter alongside frozen and prepared foods.
The Tuba cichlid is fairly peaceful for its size but territorial around breeding. Keep one fish or a single pair, and pick robust tank mates that suit fast water.
It is a biparental substrate spawner, with both parents guarding eggs laid on cleaned stone. Breeding is of medium difficulty.
Good to know
Tomocichla tuba is a rheophilic member of the family Cichlidae, built for life in current. It was once placed in the genus Theraps, and it has a streamlined body.
In the wild
The Tuba cichlid lives in fast, well oxygenated rivers on the Caribbean slope, from Nicaragua through Costa Rica to Panama. These rivers run over rock and gravel swept by current.
