Description: The Green Terror is a deep-bodied, oval-shaped fish with a pronounced head. The upper back is olive green, while the flanks are iridescent light green. Each scale has a dark green marking giving the fish several sets of broken stripes. There are two common color variants. One has white edging on the tail and dorsal fin (white saum), while in the other the edges are yellow or reddish (standard). Females are duller in coloration than the males.

The female is darker, with less contrast between colors while the males are larger and, with age, generally develop a bump on their head. The pairs form nuclear families and while they may be a bit lax with their first spawn, they become excellent parents thereafter. Sexually mature at 10-13 cm. Most fish get very territorial around breeding time, and should be kept separately during this period.

For breeding use warmer water with a temperature of 25-27°C, a pH of 6.5, and a water hardness from 5-8 dH. The female spawns on a flat surface on the tank bottom, laying 300 to 400 eggs. The fry hatch in 3-4 days and are free-swimming by the 11th. Make fequent water changes and feed them with brine shrimp. The fry are slow growing to 2 cm, then grow faster.
