One of the most popular freshwater aquarium fishes, Jack Dempseys (Scientific name: Archocentrus nigrofasciatus) are known for their aggressive nature and vibrant coloration. They are a member of the cichlid family and are native to Central America. In the wild, they can grow up to 18 inches (45 cm), but in captivity, they usually only reach about half that size. Male Jack Dempseys are typically larger than females and have more extended fins.
Jack Dempseys are relatively easy to care for as long as their tank mates are carefully chosen. They should not be kept with smaller fish or fish that peaceful in nature as the Jack Dempsey will likely bully them or even eat them. These fish also need plenty of hiding places in their tank as they can be quite territorial. A well-planted aquarium with some rocks and driftwood is ideal.
As far as diet goes, Jack Dempseys are not picky eaters and will accept most commercial foods including pellets, flakes, and frozen foods. However, like all cichlids, they appreciate a varied diet that includes live foods such as brine shrimp or bloodworms.
