Species Information
White Spotted Grouper or as they are also commonly known as the Spotted Grouper, Summan Grouper or Speckled Fin Grouper are an Indo-Pacific species that dwells in and around coral reefs and rocky areas. They use the coral reef as protection from larger predatory species, as well as a place to ambush prey with a quick burst of speed and large open mouth. White Spotted Groupers are a very hardy species, that will quickly adapt to aquarium life provided that it is maintained in a large aquarium with excellent filtration. This species is best suited for FO (fish only) or FOWLR (fish only with live rock) aquariums with other large aggressive or semi-aggressive fish species.
Aquarium Care
White Spotted Groupers have a large body (up to 12") typical to that of most grouper fish, with a large frontal body that then tapers towards their tail. Their eyes are set forward on their head with a very large mouth and strong pectoral fins. White Spotted Groupers require fairly large aquariums with excellent filtration to accommodate their size and feeding habits. As White Spotted Groupers eat large meals they end up producing a lot of waste products, which means they need excellent filtration (especially biological and mechanical) in order to keep the water quality high.
While this species is not harmful to corals, it is best suited for fish-only aquariums as it will eat any fish that it can fit in its mouth and will eat most any type of crustacean. White Spotted Groupers live near the fringes of coral reefs in the wild, they should be provided an aquarium environment that contains both live rock formations and open swimming areas. They do best with other large predatory species (triggerfish, eels, sharks, etc.) or with adult semi-aggressive species (large angelfish, tangs, etc.).
Feeding & Nutrition
White Spotted Groupers are an aggressive carnivore that primarily eats crustaceans and small fish species in the wild. In the home aquarium, they should be fed large meaty items such as shrimp, mussels, clams, chopped fish, etc. While they will consume feeder fish like goldfish or rosies, these items are not very nutritional for them and should only makeup a very small portion of their diet. The bulk of their diet should be comprised of quality marine meaty foods.
