Apistogramma sp. D62: a sought-after Colombian dwarf cichlid

Apistogramma sp. D62 is a South American dwarf cichlid sold under an aquarium trade code rather than an officially established species name. Associated with Colombia, this fish appeals to aquarists who enjoy discreet, territorial species suited to carefully arranged small aquariums. Successful care depends on soft, acidic to slightly acidic water, gentle filtration, and a layout rich in shelters. Because it is a wild-collected species, acclimation and food quality deserve particular attention. This form has intermediate availability and is therefore uncommon, and it is offered exclusively by Ton.Fish in Canada.

General species description

Apistogramma sp. D62 refers to a geographic or commercial form of Apistogramma, a genus of small South American cichlids. The D62 code is mainly used to distinguish this population or line from other forms available in the aquarium trade. As with many members of the genus, the male occupies and defends a small territory, while the female usually plays the central role in guarding eggs and fry. An aquarium arranged with separate visual territories, shelters, and quiet areas encourages natural behavior. Avoid overly active or aggressive tank mates, especially during spawning.

Geographic origin and biotope

The stated origin of Apistogramma sp. D62 is Colombia, in tropical watersheds that support numerous dwarf Cichlidae. Its natural environment corresponds to quiet sections of small streams, forest margins, or flooded areas, with water often tinted by organic matter. The habitat includes leaf litter, roots, and closely spaced shelter near the bottom. In an aquarium, soft and stable water, subdued lighting, and the presence of leaf litter or wood recreate the desired conditions more effectively than an open tank with strong circulation.

Precise locality and local name

The most practical aquarium trade name is Apisto D62, or simply D62. The number associated with the code helps distinguish this form in commerce and among hobbyists. A more precise geographic name is not used here in order to maintain a rigorous identification. To avoid hybridization and preserve the value of the line, it is best to keep the fish under its complete code, with its origin clearly recorded. This precaution is especially useful for wild forms, whose appearance can vary with age, sex, and condition.

Appearance and physical characteristics

Apistogramma sp. D62 has the typical shape of a small apistogrammoid Cichlidae: a laterally compressed body, developed fins, and a forward-facing mouth. Coloration may change with mood, social status, and breeding condition. Adult males are generally larger and have more extended fins; females often become more yellow while guarding eggs or fry. Sexual dimorphism is therefore mainly based on size, fin development, and breeding coloration. A dark substrate and subdued lighting help reveal the fish’s body contrast and changes in color.

General diet

In nature, Apistogramma sp. D62 searches for small prey in the substrate, among leaves, and around roots. In aquaria, a varied diet based on frozen or live foods is especially suitable: brine shrimp, daphnia, cyclops, and mosquito larvae from a safe source. Quality micropellets may be added once the fish is acclimated, but small frequent portions are preferable to one large feeding. Newly imported fish may be more demanding; gradual transition and excellent water quality support feeding recovery. Removing leftovers helps preserve water quality and reduces unnecessary organic waste.

In your aquarium

To succeed with Apistogramma sp. D62, choose a mature, covered aquarium arranged with several shelters. Soft and stable water, moderate circulation, and regular water changes matter more than an elaborate display. A rich and varied diet helps wild specimens regain condition quickly. Leave space between territories, monitor breeding behavior, and avoid overcrowding. This approach respects the fish’s territorial behavior and improves the chances of seeing its natural habits and coloration.
