Corumba Cichlid

About

The Corumba cichlid (Apistogramma commbrae) is a small but characterful dwarf cichlid from the river basins of Paraguay, the middle Paraná in Argentina, and the Uruguay system. It belongs to the A. commbrae species complex within the larger A. regani lineage, and the whole group can be told apart from other Apistogramma by a distinctive double spot on the caudal peduncle. Once you know to look for it, identification becomes much easier. Some males also show red and blue facial markings and a yellow throat region, suggesting the species may be polymorphic across its range. In the aquarium, this is a peaceful fish that fits well into a calm community, but there is one important consideration: it prefers cooler water than most of its Apistogramma relatives, so tankmates need to be chosen with that in mind. Small tetras and miniature corydoras from similar climates are natural companions. Breeding follows the typical Apistogramma pattern. Eggs are laid in caves or crevices and tended mainly by the female, while the male holds the perimeter. What sets this species apart is its apparent monogamy; males rarely court more than one female at a time. Fry are notably tiny at warmer temperatures, and many breeders find that dropping the temperature slightly after hatching makes early feeding much more manageable.
