The blue spot grouper?also known as the peacock hind, argus hind and bluespottted grouper?is a beautiful and hardy, albeit very aggressive, fish from the Indo-Pacific and Hawaii. Properly a sea bass from the family Serranidae, the blue dot grouper feeds primarily on other fishes in the wild, although it will also consume crustaceans; expect the same in your aquarium. For the large fish-only system with equally large fishes, the blue dot grouper is one of the more attractive members of the genus and should be given careful consideration. This fish appreciates low light environments with a couple of solidly constructed caves (these fish will dig). Only one blue dot grouper should be kept to a tank. A diet of meaty chunks of marine flesh (such as raw table shrimp) or a frozen food formulated for marine carnivores should be offered. While the blue spot grouper may appear shy on introduction, in short order, it will prove a personable, disease resistant, beautiful fish for the large fish-only (FOWLR) marine aquarium.
