Tips on Green Terrors
True their name, green terrors are an aggressive, territorial fish. They form strong breeding pairs and both parents participate in raising and protecting the fry. Green terrors are best kept as a single species or with other larger cichlids able to defend themselves. Expect territorial disputes and injuries unless they have a very large tank. These fish like to rearrange their habitats, so secure any large rocks with aquarium sealant to prevent an avalanche.
