Panther Groupers are a well known species of Grouper that have been available to marine aquarists for decades. Their unique coloration and pattern made the Panther Grouper an immediate hit with marine aquarists, but it has been their ability to adapt well to aquarium life which has maintained their populartiy for so many years. Panther Groups are relatively slow swimmers that prefer to cruis about the reef looking for possible meals and patroling their territory. Due to their large size and relatively high bio-load, the Panther Grouper requires a large aquarium with excellent biological, chemical and mechanical filtration.
