Overview

The thicklip gymnogeophagus is a subtropical eartheater for the coldwater cichlid niche. It is moderately demanding to keep.

Did you know

Male thicklip gymnogeophagus reach their peak red and blue only after a proper cold season. Without one, they stay dull, and their colors never quite pay out in full.

Caring for the thicklip gymnogeophagus

Keep a group of thicklip gymnogeophagus in a tank of at least 79 gal (300 L). Give them a sandy floor and stones to probe.

They need a genuine winter, so let the temperature fall through the cool months. Over the year, let the water range across 61 to 79°F (16 to 26°C), at a pH of 6.5 to 7.8. Holding them at a tropical temperature year round shortens their life.

Feed sinking foods and frozen fare, and taper off as the water cools. The thicklip gymnogeophagus is peaceful for a cichlid of its size, so calm community tank mates suit it.

Males develop a nuchal hump with age. It is a mouthbrooder, and breeding it is of moderate difficulty.

Good to know

The thicklip gymnogeophagus, Gymnogeophagus labiatus, has thickened, fleshy lips that it uses to probe crevices in stone for invertebrates. Unrelated cichlids in Africa and Central America share the same adaptation. It is also known as the Labiatus eartheater.

In the wild

The thicklip gymnogeophagus lives in rocky, sandy streams in Rio Grande do Sul and Uruguay, where the seasons swing hard.
