Care guide
The checkerboard cichlid, also known as the lyretail checkerboard cichlid, is a jewel of the dwarf cichlid world, prized for its intricate checkerboard patterning and elegant finnage. Native to blackwater habitats in Colombia, Venezuela, and the Brazilian Rio Negro, it inhabits soft, acidic waters rich in tannins with dense vegetation and dim lighting. Males reach up to 10 cm (4 inches) with spectacular lyre-shaped tail fins, while females are smaller at around 7.5 cm (3 inches) with rounded tails.
Despite being a cichlid, this species is relatively peaceful and shy, often hugging the bottom among plants and leaf litter. They are best maintained in a well-planted aquarium with dim lighting, plenty of hiding places, and floating plants to diffuse the light. A tank of at least 71 litres is suitable for a pair or small group. They can be combined with other peaceful, similarly-sized fish but will struggle against more aggressive tankmates.
Water conditions are critical: higher temperatures of 27-30°C and very soft, acidic water (pH 4.5-7.0) are required, with RO water nearly mandatory for breeding success. Diet should include quality sinking cichlid pellets, spirulina flakes, and plenty of frozen foods; live Daphnia is excellent for conditioning. The checkerboard cichlid is not the easiest species to find in local fish shops but rewards the dedicated aquarist with unmatched elegance.
