Written by ~Rush~. Posted in About Fish


Max size: 12-13 inches

pH: 6.5 - 7.5 

Minimum recommended tank size: 55 gallon

Aggression: Aggressive

Sexing: There is no good visual way to sex these fish. Females are typically smaller and rounder in appearance. Males can develop nuchal humps and very long fins. Males also tend to be more colorful, especially their body coloration. Females are usually a bit more drab. The orange caudal lining tends to be thicker in males. Over all Green Terrors are difficult to sex until mature.

Diet: Omnivore - Diet should consist mainly of pellet foods. Protein based and color enhancing foods are good, but spirulina infused foods should be included as well to ensure a well rounded diet.

Overview: A South American Cichlid, The Green Terror is great looking popular new world cichlid. It's colors can really only be matched by one other large cichlid commonly available in pet stores - The Jack Dempsey (Rocio octofasciatum). The Green Terror can be an aggressive fish. Some have been known to attack their tank mates relentlessly so be aware if you decide to mix these fish with others. I would say though, that when included in a group of similar sized aggressive fish they fit in just fine. A single male could be kept in a 55g. However, there are some very large males that can grow to lengths well over a foot. I don't believe these to be the norm, but those individuals would need at least a 75g tank. Green Terrors tend to be slow growers when compared to other large cichlids. Keep this in mind if you are buying a group of juvenile cichlids. The Green Terror may be out grown quickly. Otherwise they are a great addition to a cichlid community in my opinion. Overall an excellent cichlid.

The Green Terror Cichlid is often confused with the Blue Acara (Aequidens pulcher). To ensure you have (or are looking for) the right fish, please review the following article:
