Apistogramma cacatuoides, commonly known as the Cockatoo Cichlid, is a stunning and popular dwarf cichlid native to South America. Known for its vibrant colors and the male's distinctive, cockatoo-like dorsal fin extensions, this peaceful yet territorial fish makes a spectacular centerpiece for planted freshwater aquariums. Growing up to 6–8 cm, they are manageable in size and full of personality.
To thrive, Cockatoo Cichlids require a well-established aquarium decorated with live plants, driftwood, caves, and a soft substrate with leaf litter. They do best in small groups (one male with multiple females) and can be kept in a community tank with small, peaceful schooling fish like tetras and corydoras.
