Cockatoo Dwarf Cichlid

A robust dwarf cichlid whose adult males develop tall anterior dorsal rays resembling a cockatoo crest. Wild and captive males may show orange, red, yellow, black, and blue fin patterning. Females are smaller and become yellow with black brood markings.

The enlarged cockatoo-like anterior dorsal rays in males are the main recognition feature. Captive colour strains should remain identified as Apistogramma cacatuoides unless hybrid origin is known.

Males are larger, more colourful, and develop elongated anterior dorsal rays and longer pelvic, anal, and caudal fins. Females are smaller, shorter-finned, and turn bright yellow with black brood markings.

A pair can use a mature 60 cm aquarium. A male with multiple females needs more floor area, strong visual barriers, and at least one secure cave per female. Use fine sand, wood, plants, and gentle filtration.

Generally suitable for a peaceful community outside breeding, but strongly territorial around caves and fry.

Keep as a pair or a harem of one male with several females in a broad, well-structured aquarium. Each female must have an independent cave territory.

Males patrol a broad area and may pressure females. A brooding female can claim most of a small aquarium and attack any fish that approaches the fry.

Good companions include small peaceful tetras, pencilfish, hatchetfish, and calm rasboras where water requirements overlap. Avoid aggressive cichlids, fin-nippers, crowded bottom dwellers, and ornamental shrimp. Tank mates may eat fry.

This is among the more adaptable Apistogramma, especially in established captive strains. It can live in moderately hard neutral water, though breeding results are often better in softer slightly acidic conditions.

A small-invertebrate predator that should receive varied live, frozen, and high-quality prepared foods.

Feed small portions once or twice daily. Newly imported fish may need live or frozen foods before accepting pellets. Avoid a long-term single-food diet.

A cave spawner with maternal brood care. The female lays eggs on a cave ceiling, guards eggs and larvae, and leads the fry. Captive strains often breed readily when adults are well conditioned and secure caves are available.
