Overview

  • The Convict Cichlid (Amatitlania nigrofasciata) is a hardy Central American cichlid with bold black bars. It is one of the most familiar cichlids in the hobby.
  • Native to Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica and Panama.
  • Grows to about 6 in (15 cm) standard length.
  • Easy to keep and breed, but aggressive.

Feeding

  • Very unfussy. Accepts most foods.
  • Keep the diet varied for the best condition.

Habitat

  • Rocks, bogwood and roots for hiding places and spawning sites, plus clay pots laid on their side.
  • Plants may be uprooted, since convicts dig.
  • Water: 75–82°F (24–28°C), pH 6.0–8.0, GH 5–25.

Fish Care

  • Very hardy and adaptable.
  • [UNVERIFIED] Plan for at least a 30-gallon (114-liter) tank for a pair. Seriously Fish gives no minimum size.

Compatibility

  • Not a community fish, even though it is often sold as one.
  • Best in a species tank. In a very large tank it can live with robust Central American cichlids.

Aquarium Behavior

  • Aggressive and territorial, and violent when breeding.
  • Will take on fish several times its size.

Breeding

  • One of the easiest fish to breed.
  • Often a male and female placed together will pair. Otherwise raise a group of juveniles together.
  • Be ready to move extra fish once a pair forms. The male won’t tolerate others in his territory.
