Apistogramma Cacatuoides

Overview

The Cockatoo Dwarf Cichlid (Apistogramma cacatuoides) is one of the hardiest and most popular dwarf cichlids, named for the tall, spiky front rays of the male's dorsal fin that resemble a cockatoo's crest. It comes from slow-moving streams of the upper Amazon basin (Peru and Colombia). Males are larger and more colourful, with bright, extended fins; females are smaller and turn yellow-and-black when guarding fry. Line-bred forms such as "Double Red" and "Triple Red" are widely available.

Water Parameters

• Temperature: 24–29°C (75–84°F)
• pH: 6.0–7.5 (tolerates slightly higher)
• Hardness: 2–15 dGH

Tank Setup

• Minimum tank size: 60 litres for a pair or one male with two females
• Decor: Sand substrate, caves (coconut shells or small pots), driftwood, leaf litter and plants to break up sight lines

Diet

• Base: Quality micro pellets and granules
• Treats: Frozen or live bloodworm, brine shrimp, daphnia

Temperament & Tank Mates

• Temperament: Peaceful towards other species, but territorial near its cave — especially when breeding
• Best companions: Small schooling "dither" fish (tetras, pencilfish, rasboras) and Corydoras
• Avoid: Other Apistogramma in small tanks; adult dwarf shrimp are usually fine but shrimplets may be eaten

Common Issues

• Males can harass females if there are not enough caves and hiding spots
• Sensitive to rising nitrate — keep up regular water changes
• Lifespan: around 5 years
