Convict Cichlid

About

The convict cichlid (Amatitlania nigrofasciata) is one of the most recognizable freshwater fish in the hobby, wearing bold black vertical bars across a pale grey body. The pattern that earned it its common name. Native to Central America, it ranges across Pacific and Atlantic slope river systems from El Salvador and Guatemala down to Honduras, where it occupies everything from small rocky streams to the shallows of fast-moving rivers, tucking into crevices and debris for shelter. In the aquarium, convicts are genuinely forgiving fish that tolerate a wide range of conditions and eat almost anything offered, which makes them technically accessible for beginners. The catch is temperament. This is not a community fish, despite how frequently it gets sold as one. Convicts are territorial and aggressive at the best of times, and when a pair begins breeding, they become something else entirely. Capable of bullying and injuring fish considerably larger than themselves. For a hobbyist who wants to dedicate a tank to a single species and experience real cichlid parenting behavior, though, convicts are hard to beat. Both parents guard eggs and fry with remarkable intensity, the female tending the spawn while the male aggressively defends the surrounding territory. Breeding happens readily with minimal intervention, and fry are straightforward to raise. Several captive color forms exist, including a popular pink variant.
