Overview

The Even-Spotted squeaker is a small, peaceful catfish from Lake Tanganyika, at home in a rocky, hard-water tank. It asks a little more of its keeper than the easiest fish do.

Did you know

The Even-Spotted squeaker is often confused with the cuckoo catfish and can use the same trick. It is a part-time brood parasite that can slip its eggs into a mouthbrooding cichlid's clutch.

Caring for the Even-Spotted squeaker

Give a group of Even-Spotted squeakers at least 21 gal (80 L). Build the tank from stacked rocks forming caves and crevices over sand, with clear swimming space. Strong filtration and good oxygen hold conditions steady.

Keep the water hard and alkaline with a high mineral content, at a pH of 7.5 to 8.5. A temperature of 75 to 82°F (24 to 28°C) suits it. Feed a mixed diet of sinking pellets, frozen bloodworms and algae-based foods, which it takes readily.

Keep Even-Spotted squeakers in a group of four or more. A group schools and forages actively over rock and sand, by day as well as at night. They are peaceful, and their modest size and calm nature make them good companions for Tanganyikan and other hard-water cichlids.

Breeding is possible but hard. It spawns by scattering eggs, which makes it easier to raise than the cuckoo catfish. Keepers often spawn it in a separate tank with the flowerpot method.

Good to know

The Even-Spotted squeaker is a dwarf squeaker in the family Mochokidae and one of the smaller members of its genus. It has the group's bony head shield and lockable spines, with neat dark spots on a pale body.

In the wild

The Even-Spotted squeaker is endemic to Lake Tanganyika. Its name, petricola, refers to its life among the rocks of the shoreline. The lake water is hard, alkaline and very stable.
