Overview
The Sveni eartheater is one of the better eartheaters to start with. It is now well established in the hobby and bred in reasonable numbers.
Did you know
Sven Kullander described many eartheaters himself. With this species, his colleagues filed his name into the genus he curated.
Caring for the Sveni eartheater
Keep five or six Sveni eartheaters in at least 119 gal (450 L), with a long open floor. Give them fine sand deep enough to sift and work.
Hold the water at 77 to 84°F (25 to 29°C) and a pH of 5.5 to 7.2. Feed sinking granules and frozen foods often, in small amounts rather than one large meal.
The Sveni eartheater is peaceful for its size and mixes with calm, mid-sized South American fish. Like all eartheaters, it monopolizes the bottom.
It is a delayed mouthbrooder. The eggs are laid on a cleared surface and taken into the mouth a day or so later. Breeding it is of medium difficulty.
Good to know
The Sveni eartheater was described in 2010 and honors Sven Kullander, the systematist behind much of the modern arrangement of South American cichlids.
In the wild
The Sveni eartheater sifts sand in the tributaries of the Tocantins basin in Brazil, in warm water running soft to neutral.
