Overview

The granulated synodontis is a big, aggressive catfish for a large Tanganyikan cichlid tank. It is for experienced keepers who can hold water quality steady.

Did you know

The granulated synodontis is one of the holy grail catfish of the hobby, and adults command high prices. Part of the reason is that it grows slowly and is rarely exported.

Caring for the granulated synodontis

Give a granulated synodontis a large, mature tank of at least 79 gal (300 L). Pile rockwork over a sandy floor, and run heavy filtration.

It demands clean, stable, hard and alkaline water, at 73 to 81°F (23 to 27°C) and a pH of 8.0 to 9.0. It is intolerant of poor water quality and reacts badly to neglect, so keep conditions pristine and consistent. Feed quality sinking foods, frozen items and some greens.

As an adult, it turns territorial and aggressive toward other bottom dwellers, so it is usually kept as a single specimen. It suits a large hard-water Tanganyikan setup with robust cichlids that can hold their own. It has never been bred in captivity.

Good to know

The granulated synodontis has a slate-gray to olive body with a fine, granular skin texture. Juveniles carry a spotted pattern that fades with age. It belongs to the family Mochokidae and is also sold as the granular catfish.

In the wild

The granulated synodontis is a prized endemic of Lake Tanganyika. It lives over rocky coasts in hard, alkaline, oxygen-rich water.
