Cockatoo dwarf cichlid
Apistogramma cacatuoides
intermediate careOverview
The cockatoo dwarf cichlid (Apistogramma cacatuoides) is the friendliest gateway into the Apistogramma genus — a small, spirited South American cichlid where the male flares a raised, cockatoo-crest dorsal fin in fiery red and orange. Hardier and more food-flexible than most apistos, it still rewards a mature, planted tank and a keeper who enjoys watching cave-spawning behaviour up close.
Tank & water
A harem is comfortable in 75 litres (20 gallons) with a longer footprint for territories.
- Temperature: 24–28 °C from a steady heater.
- Water: best around pH 6.0–7.0 and soft to moderate hardness, though cacatuoides tolerates harder water than most apistos. Test with a kit.
- Caves and cover: multiple small caves — clay pots, coconut huts — plus plants and leaf litter to define female territories.
- Upkeep: a mature filter with gentle flow and regular water changes.
Feeding
Cockatoo cichlids are carnivore-leaning omnivores that forage the lower levels. Feed small sinking pellets or micro foods plus frequent frozen or live bloodworm, brine shrimp and daphnia. A fine sand bed lets them sift naturally. Feed modest amounts once or twice daily.
Tankmates
Pair them with peaceful upper-water dither fish — small tetras, rasboras and pencilfish — that draw them out and stay clear of the substrate. Avoid other bottom-territorial cichlids and boisterous or nippy species. A Bolivian ram can share a larger tank if there is space for separate territories. Keep stocking modest; check how many fish in an aquarium.
Cockatoo dwarf cichlid — frequently asked questions
Is Apistogramma cacatuoides a good first apisto?
Yes. Of the many Apistogramma species, cacatuoides is one of the hardiest and most forgiving, tolerating a wider pH range than most and accepting prepared foods readily. It is the usual recommendation for a keeper trying dwarf cichlids for the first time, though it still needs a mature, stable tank.
How should I stock cockatoo cichlids — pairs or harems?
A harem of one male with two or three females works best. Males are polygamous and each female defends her own small cave territory, which spreads the male's attention and reduces stress. Give plenty of caves and sightline breaks so females can hold separate spaces.
Do cockatoo cichlids need live food?
They do best with regular meaty foods, but unlike some apistos they readily take quality pellets and frozen fare. A staple of small sinking foods plus frozen or live bloodworm and brine shrimp keeps them coloured and in breeding condition.
