Overview

The purple earth eartheater is a subtropical cichlid that wants a cool season. That makes it one of the few cichlids suited to an unheated tank in a temperate room. It is best kept by someone with a little experience.

Did you know

The purple earth eartheater is named after dirt. Its species name, terrapurpura, is Latin for purple earth, after the ground it was collected over.

Caring for the purple earth eartheater

Keep a group of purple earth eartheaters over sand, in a tank of at least 53 gal (200 L). They are mostly peaceful and safe with other community fish. Breeding them takes moderate effort.

Keep the water at 61 to 79°F (16 to 26°C) over the year, with a pH of 6.5 to 7.8. Let the temperature drift down through winter, since the seasonal swing is part of its care rather than a tolerance. Skipping the cool period shortens its life.

The fish go dull and quiet for a few months in the cold, then color up hard in spring. Feed sinking foods and frozen fare, and give less in the cold months.

Good to know

Gymnogeophagus terrapurpura is a cichlid of the family Cichlidae, described in 2016. Gymnogeophagus means naked eartheater, for the missing spine on the first part of the dorsal fin. That trait separates the genus from Geophagus.

In the wild

The purple earth eartheater sifts sand in lowland streams of Uruguay. Winters there are genuinely cold, and summers are warm.
