Overview
The red hump eartheater is a sand-sifting cichlid from Colombia and Venezuela that lives in groups. It is an easy fish to keep.
Did you know
The red hump eartheater hybridizes readily with related species, just as easily as it spawns with its own kind.
Caring for the red hump eartheater
Keep a group of red hump eartheaters in at least 53 gal (200 L). Give them a deep, soft sand bed and open swimming space, with some rocks and wood.
Keep the water at 72 to 82°F (22 to 28°C) with a pH of 6.0 to 7.5. They spend the day taking mouthfuls of sand and sifting out food, and a soft bottom lets them feed naturally. Feed sinking pellets and frozen foods as well.
They are mostly peaceful, but males chase rivals, so avoid keeping two males in a small tank. Keep one male to several females to spread out his attention.
Males develop a bright red or orange nuchal hump as they mature, which gives the fish its common name. It is one of the easiest eartheaters to breed and spawns readily. It is an immediate mouthbrooder, and the female holds the eggs in her mouth for around two weeks.
