The Apistogramma cacatuoides is commonly known as the Cockatoo Dwarf Cichlid or Big Mouth Apistogramma. The Apistogramma originates in the streams and backwaters of South America. This strain has been selectively bred for its brilliant orange coloration. The body of these fish is elongated, with a prominent dorsal fin. The rear part of the dorsal fin, as well as the tail, has a striking orange coloration.The Orange Cockatoo Cichlid should be kept in an aquarium that is 30 gallons minimum, with densely planted groupings. They require plenty of open swimming areas but also need hiding places. A fine gravel to sand substrate is recommended. Although a semi-aggressive fish, the Apistogramma is also timid and should not be housed with large, aggressive fish. They require good water conditions, and regular water changes are a must.
