Cockatoo Cichlid

Geographic Origin and Biotope: Widespread in the Amazon basin, from Peru to Colombia and Brazil. Unlike most congeners, it prefers "whitewater" (muddy white waters) or shallow "clearwater", near banks rich in roots.

Taxonomy and Morphology: Cockatoo Dwarf Cichlid (Apistogramma cacatuoides). Among the best-known dwarf cichlids. The name derives from the spectacular dorsal fin of the males, whose first rays are enormously elongated, resembling the crest of a Cockatoo.

Social Behavior: Strongly polygamous. The male reigns over an extensive territory that includes the dens of several females. Highly aggressive between males (if there is no space, they will fight to the death) but indifferent towards mid-water fish.

Coloration and Sexual Dimorphism: Countless morphs exist (Double Red, Triple Red, Orange Flash). The male flaunts fiery red or orange fins checkered with black and a massive body. The female is stocky, small, brown, and is tinged with a dazzling "wasp yellow" (with a black band) during parental care.

Aquarium Setup: Minimum 80 cm (32 inches) tank for a trio. Sand bottom mandatory so as not to tear the gills during sifting. Create dense visual barriers and provide well-spaced coconuts or overturned pots to act as dens.

Diet and Feeding: Omnivore with a carnivorous tendency (Micro-predator). Feed deeply with frozen food (bloodworms, brine shrimp) or live (daphnia). Sinking dry foods (granules) are accepted, but if used exclusively they cause intestinal occlusion.

Water Quality: Perhaps the most robust and tolerant Apistogramma. Accepts moderately hard tap waters and pH up to 8.0 without problems, which makes it the ideal species for those approaching Dwarf Cichlids for the first time.

Compatibility and Tankmates: Perfect partners: small Characins (Cardinal Tetra, Pristella) or mid-water Cyprinids acting as "dither fish". Absolutely avoid coexistence with Corydoras: in the brooding phase, the female cacatuoides will blind or disembowel the catfish that dare to approach the den.

Aquarium Reproduction: Very easy. Cave spawning with a clean ceiling. The mother broods alone, chasing anyone (including the male) from a 30 cm radius. After 3-4 days the eggs hatch; the young are led to graze on the bottom for weeks.

Risks and Diseases: Extreme selections ("Triple Red") have made males prone to dwarfism, deformed humps or spontaneous tumors. A coarse gravel bottom will rapidly lead to fatal mouth injuries when trying to dig the den.
