Habitat in the wild
First described in 1951, Apistogramma cacatuoides is native to various South American countries, including Brazil, Colombia, Peru, and Bolivia. This striking cichlid thrives in the Amazon, Ucayali, and Solimões River basins, where it prefers small, shallow streams and lagoon-like waters. These habitats often feature a substrate rich in fine sand and decomposing organic matter, with thick layers of leaves providing essential cover.
Cockatoo cichlids flourish in blackwater environments, characterized by tannin-stained waters that can vary significantly with the seasons. As leaves decay, they create more acidic and softer water conditions, ideal for the cichlid’s health. Densely vegetated areas with submerged plants, floating vegetation, and overhanging branches serve as vital shelters and breeding territories.
Socially, Apistogramma cacatuoides are polygamous, living in harems that consist of an alpha male and several females. This dynamic adds to their charm, showcasing interesting behaviors that make them a joy to observe in the aquarium.

Decor
As for the décor it should be mentioned that dwarf cichlid look better on a dark background. Use a soft substrate such as fine sand or small-grain gravel. This allows the cichlids to dig and sift through the substrate, which is a natural behavior for them.
Cockatoo cichlid prefers an aquarium tightly covered with plants, with scattered and not bright light. Provide moderate lighting levels. Avoid extremely bright lights, as Cockatoo Cichlids are more comfortable in dimmer lighting conditions that mimic their natural habitat.
Lots of caves are necessary. Fish will protect them from the other aquarium inhabitants. Provide plenty of driftwood and rocks to create hiding places, caves, and territories for the cichlids. These materials also help create natural boundaries and break the line of sight, reducing aggression and stress. Ensure that the rocks are stable and won’t topple over. Divide the aquarium into sections so that each would have its own shelter and belong to one female.
It’s a must to add different kind of shelters into the aquarium – one for each cichlid female, plus they should be in different spots of aquarium for each female to have its own territory. They like aquarium with high number of plants, soft light and small amount of dry leaves in it.
Diet
Cockatoo cichlids are omnivorous and, in the wild, they thrive on a diet rich in various insects found among the fallen leaves on the water’s bottom. To replicate their natural feeding habits in an aquarium, it’s essential to provide a varied and balanced diet.
In captivity, cockatoo cichlids accept all types of live, frozen, and artificial foods. Here are some dietary recommendations to ensure they receive the necessary nutrients for optimal health and vibrant coloration:
- Staple Foods: High-quality pellets or flakes specifically formulated for cichlids should be a staple in their diet. Look for products that offer balanced nutrition tailored for small-sized cichlids.
- Live and Frozen Foods: Incorporating live and frozen foods significantly benefits cockatoo cichlids. Offer a variety of options, including:
- Brine shrimp
- Bloodworms
- Daphnia
- Small insect larvae
These foods not only provide essential nutrients but also help replicate their natural diet, promoting their health and enhancing their colors.
Tank mates
Cockatoo cichlids make an excellent addition to community tanks, known for their peaceful demeanor and compatibility with various fish species that share similar water requirements. When selecting tank mates, consider non-aggressive fish of equal size to ensure a harmonious environment.
These cichlids thrive in both pairs and harems, typically consisting of one male and two to three females. If you’re interested in breeding or maintaining a small group, aim for a male-female ratio of 1:2 or 1:3. This approach helps minimize aggression and fosters a more natural social structure. In spacious tanks, you can even accommodate more than one male, allowing for a dynamic and engaging aquatic community.
Here are some suitable tank mates:
- Harlequin Rasboras (Trigonostigma heteromorpha)
- Neon Tetras (Paracheirodon innesi)
- Ember Tetras (Hyphessobrycon amandae)

Breeding
Cockatoo cichlids are fascinating polygamous fish that thrive in harems, typically consisting of one alpha male and several females. In these social structures, the alpha male defends the territory from other males, ensuring a safe environment for breeding.
During spawning, females can lay up to 80 eggs, which they adhere to the ceiling of a cave. After the female deposits her eggs, she takes on the responsibility of caring for them while the male guards their territory.
To create a suitable spawning environment, it’s essential to provide various hiding spots, such as flowerpots, coconuts, and bogwood. The ideal water conditions for spawning include a pH below 7.5, with optimal parameters being a pH of 6.8 to 7.2, hardness of 10 or less, and a temperature range of 78°F to 84°F (26°C to 29°C). Generally, softer and more acidic water promotes higher breeding success.
To find a compatible pair of cockatoo cichlids, it’s advisable to purchase six juveniles. As they grow together, this increases the likelihood of forming a successful breeding pair or harem. Keep in mind that some interbreeding may lead to issues such as sterility or spinal deformities, but with luck, you may end up with a thriving group.
During the spawning ritual, the male will approach the female, curve his body, and display his most vibrant colors to attract her attention. The female then lays her reddish eggs on the cave walls, and the male fertilizes them before departing to monitor the surroundings.
Interestingly, if multiple females are present, they may “steal” each other’s fry, incorporating them into their own schools. The eggs typically hatch within 3 to 4 days, and shortly after, the fry begin to swim. It has been observed that if the water temperature is below 21°C, the majority of fry will be female, while temperatures above 29°C tend to produce more males. pH levels also play a role in determining fry gender.
For successful fry development, it’s crucial to maintain stable tank parameters during the first three weeks. The juveniles grow rapidly and can be introduced to nauplii as food within a few weeks, although powdered foods, vinegar eels, and egg yolk are also suitable options for initial feeding.
