A highly popular and vibrant dwarf cichlid native to the Amazon basin. Named for the male's flamboyant, crest-like dorsal fin. They are cave-spawners that require a fine sand substrate (which they sift through their gills) and plenty of hiding spots. While generally peaceful in community tanks, they become fiercely territorial when breeding.

Male
Males are larger, display the spectacular 'cockatoo' dorsal fin, and exhibit vivid colors. Males are highly territorial toward other male Apistogrammas. Usually kept singly or as the patriarch of a harem (one male to multiple females).

Also known as: Double Red, Triple Red, Orange Flash, Super Red
Female
Females are significantly smaller and predominantly yellow-grey. When breeding, they turn a striking, vibrant yellow and become fiercely protective of their cave and fry, to the point of chasing away the male or much larger fish.

Cockatoo Dwarf Cichlid Care Guide Summary
The Cockatoo Dwarf Cichlid, scientifically known as Apistogramma cacatuoides, belongs to the Cichlids - South American family group. Adults reach a maximum size of approximately 7.5 cm and have a compressed body shape with a moderate growth rate. Classified as semi-aggressive, this species primarily occupies the bottom zone of the aquarium and produces a low level of biological waste.
To thrive, the Cockatoo Dwarf Cichlid requires a freshwater only aquarium with a minimum volume of 60 litres and a tank length of at least 60 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 6–7.5 and a general hardness of 2–10 dGH. A low water flow is preferred.
Due to its specialist needs, the Cockatoo Dwarf Cichlid is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 2 varieties: Male and Female. Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Cockatoo Dwarf Cichlid Habitat Setup
When setting up an aquarium for the Cockatoo Dwarf Cichlid, a low water flow best suits their natural preferences. Because this species occupies the bottom zone, the aquarium layout should prioritise sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour, driftwood, which can serve as both a hiding place and a dietary supplement, and leaf litter or blackwater tannins to replicate their natural soft-water habitat.
Cockatoo Dwarf Cichlid Compatibility Notes
Classified as semi-aggressive, the Cockatoo Dwarf Cichlid is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, ornamental shrimp are not safe companions and territorial behaviour may cause issues if hiding spots or floor space are limited. Selecting tankmates that favour different water layers from the bottom zone can help reduce competition and territorial overlap.
Cockatoo Dwarf Cichlid Feeding & Diet Considerations
The Cockatoo Dwarf Cichlid will hunt and eat ornamental shrimp, making it unsuitable for shrimp-focused setups and will eat fry, so breeding efforts in the same tank are unlikely to succeed.

Kribensis
Pelvicachromis pulcher
A vibrant and highly popular dwarf cichlid native to the slow-moving rivers of West Africa. Unlike Rift Lake African cichlids, they prefer soft, slightly acidic water and densely planted tanks. They are generally peaceful in a community tank but become fiercely territorial and aggressive when breeding, often digging pits in the substrate and claiming the bottom zone. They are cave spawners and require hiding spots like driftwood or coconut shells.
German Blue Ram
Mikrogeophagus ramirezi
A strikingly colorful dwarf cichlid native to the Orinoco River basin. Famous for its vibrant blue spangles and peaceful demeanor compared to larger cichlids. They are strictly thermophilic (require high temperatures of 27-30°C / 81-86°F) and thrive in soft, acidic water. As 'earth-eaters' (Mikrogeophagus), they sift sand for food and form monogamous pairs.
African Butterfly Cichlid
Anomalochromis thomasi
A peaceful, colorful dwarf cichlid from West Africa. Unlike many cichlids, it is plant-safe and generally suitable for community tanks. It is famous in the hobby as an efficient biological control for pest snails.
Texas Cichlid
Herichthys cyanoguttatus
The Texas Cichlid is the only cichlid species native to the United States. Known for their striking pearlescent blue/green spots and extreme territorial behavior, they require large tanks and robust filtration. They are notorious for rearranging aquariums, digging massive pits, and destroying live plants.
Dwarf Gourami
Trichogaster lalius
A peaceful to semi-aggressive labyrinth fish native to South Asia. Famous for their brilliant metallic blue and red stripes. While generally suitable for community tanks, males are territorial toward each other and similar-looking fish. They are sensitive to water quality and prone to Iridovirus if stressed. Requires access to the surface to breathe.
Freshwater Angelfish
Pterophyllum scalare
The most iconic South American Cichlid, known for its distinct arrowhead shape and majestic fins. While domestic strains are hardy, they remain cichlids: they are semi-aggressive predators that will eat any fish small enough to fit in their mouths (like Neon Tetras). They form loose shoals as juveniles but pair off and become territorial as they mature. Height is more important than length for this species.
