My green severum 75 Gal. tank The Green Severum, also known as the Banded Cichlid, is a color variation of Heros severus Severum. Severum have an iridescent sheen to their scales and off-white to green background color. Black spots travel along the lower body, starting behind the pectoral fin and a black band reaches across the caudal end of the body. The Green Severum is a trusting fish, and will often accept food directly from their owner's hand. The Green Severum requires a 30 gallon or larger tank that is at least 40 inches long and 20 inches tall. The larger the tank the better. They prefer a lightly-planted tank with a soft bottom and a few rooted plants. Adding a few large rocks would be appropriate as long as there is still plenty of open room for swimming and the water is not affected. Severum can be aggressive when spawning, and for this reason should only be housed with other semi-aggressive fish. Differentiating between the male and female is very difficult. Positive identification can only be made after close examination of the genital papillae. The males normally have pointed fins and reddish-brown spots and "worm-like" markings on their heads. Females usually have a dark patch on the dorsal fin. The Green Severum does not pair as readily as other South American Cichlids, and may take a bit longer. Providing the male with a choice of females will help. An open breeder, the female can lay as many as 1,000 eggs on rocks. The water should be mildly acidic, soft with a pH of 6.0-6.5 and a hardness of dH 5. The temperature should range from 77-82°F. The Green Severum carefully tends to its fry. The Green Severum is a carnivore and will eat most prepared and frozen foods, including freeze-dried bloodworms, tubifex, and ocean plankton, as well as flake food and Cichlid pellets.
