Green Terror

A South American cichlid, the Green Terror is a colorful fish that reaches lengths of around 9". As the name implies this species can be very aggressive, especially adult specimens. This is not guaranteed, however, and peaceful individuals are often observed. Juvenile Green Terrors are often sold in pet shops, as well as fish similar enough to be mistaken for this species (including the Blue Acara).

The fish is somewhat deep-bodied with a prominent head. Adult males develop a pronounced forehead hump, a common cichlid trait. Juveniles are tan colored with silver-blue flecks and lack the bright blue, green, and orange coloration and long, flowing fins of adult specimens.
