The Green Terror Cichlid (Andinoacara rivulatus) is a long time favourite in the freshwater aquarium hobby. Native to Peru and Ecuador, this species is extremely colourful, especially as it approaches adulthood. Males are the most colourful sex, but females are also very colourful. Both sexes have generous blue-green facial and body coloration and an orange margin on the dorsal fin and tail. Males grow noticeably larger and will typically develop extended dorsal and anal fins as well as a nuchal hump, which are all characteristic of many cichlid species.
The Green Terror Cichlid will thrive in an aquarium with a sandy substrate and plenty of refuge such as clay pots, driftwood, and rock formations. It typically will not eat ornamental plants, but it does like to do a fair amount of digging, so floating plants and plants that attach to driftwood and rockwork are recommended. As its name states, this cichlid can be aggressive, especially in the confines of a smaller tank. It can be kept with other large cichlids, plecos, catfish, and other large, durable species in a very large tank as long as there is plenty of cover with decor to create broken lines of sight. Territoriality is typically at its peak during spawning. If spawning is desired, tank mates of other species should be avoided altogether, and care must be taken to ensure that the male Green Terror does not bully or kill the female. It is best to grow a group of juveniles together and allow them to pair off naturally, then give each pair its own tank if one wishes to start a breeding program with this species. Dwarf shrimp and other invertebrates should not be kept with the Green Terror Cichlid. Due to its size and waste production, regular water changes and maintenance are a must.
Feeding is simple for the unfussy Green Terror Cichlid. High-quality dry, frozen, and live meaty foods will all be readily accepted. Vegetable matter is also required. Quality and variety are the keys to a diet that will ensure that this fish maintains optimal health and coloration.
