Groupers belong to the Serranidae family. The most common genus of this family of fish found in the aquarium trade is Cephalopholis. Groupers belonging to the genera Variola, Cromileptes, and Grammistes are also available. Most Groupers grow quite large (over 12 inches) in an aquarium and frequently outgrow the average-sized aquarium. The largest member of this family can attain a size of over eight feet in length in the wild. Groupers are closely related to Pseudochromis, and can be recognized by their large mouth, and the three spines or plates on their gill covering. Some Groupers are called Soapfish, and can secrete a mucus of toxins to ward off predators. Groupers are found throughout the world, and are most commonly associated with coral reefs or rocky areas. Most Groupers are solitary in the wild, spending their time in caves or overhangs, waiting for a passing meal. The diet of these fish consists of fish, crustaceans, and cephalopods.

Groupers are very hardy aquarium specimens, and can adapt to a wide range of conditions. A large aquarium with adequate hiding places is necessary to maintain Groupers in an aquarium. It is advisable to keep only one species of Grouper per tank, as these fish may become aggressive towards other tankmates and themselves. In most cases, no distinguishing characteristics differentiate males from females, and the breeding of these fish in an aquarium is extremely difficult.
