Care notes

'Eartheater' cichlid — constantly sifts mouthfuls of sand filtering out food, then spits the sand back out. Requires a deep sandy substrate (3+ inches). Fascinating behavior. Pair-bonding substrate spawner with biparental care.

Check the whole aquarium. Tank size alone does not establish compatibility. Confirm adult size, water overlap, social grouping, territory, diet, and the individual animals before stocking.
