Overview

Robertson's cichlid is a large Central American sand-sifter that works the bottom of a big tank. It is a step up from the easiest cichlids.

Did you know

Robertson's cichlid looks as if it belongs in a different lake. It is spangled in turquoise like a Malawi peacock, but it spends the day mouthing sand and sifting it for scraps, Amazon-style.

Caring for the Robertson's cichlid

Give a Robertson's cichlid at least 106 gal (400 L), with a deep, open floor of fine, soft sand. It feeds by taking mouthfuls of sand and sifting them, so keep coarse gravel out of the tank. Add some wood and rock for structure, and run strong filtration to handle the sand it keeps stirring.

Keep the water neutral to hard, at 75 to 84°F (24 to 29°C) and a pH of 7.0 to 8.2. Feed sinking pellets and frozen foods, and let a good share reach the bottom.

Keep a single fish or a bonded pair, and treat it like a mild, large eartheater that needs room to work. It is fairly peaceful for its size but claims a bottom territory at breeding time. Choose sturdy, calm tank mates, and give it enough space to plow the sand without constant conflict.

It is a substrate spawner, and both parents guard the eggs and fry. Breeding it is moderately difficult.

Good to know

Cribroheros robertsoni is a cichlid of the family Cichlidae, and among the largest of the sieve-feeding heroes. Its genus name refers to the sieve-like way these fish strain food from the sand. It is sometimes called the false firemouth, and other names include the turquoise sifter cichlid and the emerald cichlid.

In the wild

Robertson's cichlid ranges along the Atlantic slope of Central America, from southern Mexico to Honduras. It sifts sand in slow rivers and lakes.
