Overview
The checkerboard cichlid is a small, shy and peaceful dwarf cichlid for a calm, dim tank with soft, acidic water. It suits a keeper past the beginner stage.
Did you know
A male checkerboard cichlid flicks his tail at rivals and at females that are displaying. That tail gives the fish its other common name, the lyretail checkerboard cichlid.
Caring for the checkerboard cichlid
Keep checkerboard cichlids in a group so the fish can pair off naturally. A tank of at least 20 gal (75 L) gives a group the space and territories it needs. Make it dim, with leaf litter, driftwood, fine sand and plenty of low cover. That cover lets the fish feel secure enough to come out into the open.
Keep the water at 79 to 86°F (26 to 30°C) and a pH of 5.0 to 6.5. Start from soft water and add plenty of botanicals, such as alder cones, to tint and acidify the tank. Subdued lighting and floating plants help the fish settle and show their best color.
Feed small live and frozen foods such as brine shrimp, daphnia and cyclops, since many individuals ignore dry food at first. Choose gentle tank mates such as small tetras, pencilfish and Corydoras rather than anything pushy. Males set up small territories and display to each other, but serious aggression is rare.
Mature males grow a forked, lyre-shaped tail edged in red and blue. The checkerboard cichlid is an open spawner that usually lays its eggs on a leaf or flat surface. The female takes on most of the care of the eggs and fry, while the male guards the wider area. Soft, acidic water is generally needed for the eggs to develop.
Good to know
The checkerboard cichlid, Dicrossus filamentosus, is a dwarf cichlid in the family Cichlidae. Its common name comes from the double row of dark, checkerboard-like blotches along its flanks.
In the wild
The checkerboard cichlid lives in the Rio Negro and Orinoco drainages of Colombia, Venezuela and Brazil. It is found in shallow, slow blackwater streams shaded by forest. The water there is warm, extremely soft and very acidic, deeply stained with tannins and often barely holding any measurable hardness.
