The Miniatus Grouper is commonly referred to as the Coral Grouper, which is a hardy and vividly colorful species. With its beautiful and bright color, it makes a delightful yet aggressive addition to any tank. It is equipped with large mouths as it is highly predatory fish. It is highly aggressive and highly territorial species that should be added to an aquarium as the last inhabitant. Since it is easy to keep, it makes a great choice for a beginner aquarist. The Miniatus Grouper should be kept in a tank not less than 100 gallons along with plenty of live rock structure that will provide them multiple hiding places. The Miniatus Grouper is very well known for their digging behavior and should be provided with thick sand bed in the tank. Since it is a big eater, the tank should be well equipped with a quality protein skimmer in addition to strong biological and mechanical filtration. The Miniatus Grouper should be housed with the tank inhabitants with smaller size. Since it ravenously dines on small fish and motile invertebrates, it is not recommended for a reef tank. The Miniatus Grouper is carnivorous and should be fed with a wide variety of meaty food items such as live, frozen, freeze-dried, and vitamin-enriched brine shrimp (as juveniles), mysis shrimp, other meaty marine foods. It should be fed at least 3-5 times a week for their continued good health.
They should not be kept with shrimp or small fish that they will mistake for food. They are great for fish-only tanks.Groupers come from a family of fish known as Sea Bass. These fish have stout bodies with large mouths filled with more than one set of teeth. Groupers use powerful suction to engulf their prey by quickly opening their mouths. Their prey is swallowed whole instead of being chewed.
