Cockatoo Dwarf Cichlid
Apistogramma cacatuoides
About
The cockatoo dwarf cichlid is a well-known Apistogramma from South America, named for the male’s tall, spiny dorsal fin. Males are vividly coloured; females turn yellow with bold black markings when brooding. They are classic cave-spawning dwarf cichlids: females guard eggs and fry in a cavity while males patrol a wider territory. Soft to moderately soft water, warm temperatures, and a structured tank with coconut shells, tubes, or rock caves suit them. Harem setups (one male with several females) work in long tanks with multiple territories.
Feeding & Diet
Small sinking pellets; frozen cyclops, brine shrimp, or bloodworm; live foods in moderation; include occasional vegetable matter.
Frequency: 1–2× daily
Feed after lights-on; dominant males can outcompete shy fish—watch body condition.
Habitat
Native Region: Peru, Brazil, Colombia (Amazon basin)
Blackwater and clearwater tributaries; leaf litter, roots, and submerged wood.
Multiple caves along tank length; dim light; leaf litter optional; gentle flow; harem needs footprint, not just volume.
Behavior
Activity Level: Moderate
Strongly territorial males; females fiercely defend fry; not ideal with large or boisterous fish.
Breeding
Difficulty: Moderate
Type: Egg layer
Sexual Dimorphism: Males larger with spectacular dorsal and brighter colours; females smaller, yellow with black “mask” when breeding.
Female leads in cave spawning; guards fry in cave; male may be removed if overly aggressive; frequent water changes can stimulate breeding.
Tank Setup
Substrate: Sand
Plant Safe: Yes
PVC pipes, coconut halves, or rock caves—smooth edges; floating plants for shade.
