Miniatus Grouper
The Miniatus Grouper, also known as the Miniata Grouper, Coral or Blue-Spot Rockcod, Coral Hind, and Coral Grouper, is a common and popular fish along the coral reefs of the Indo-Pacific, and it makes a most spectacular addition to a large home aquarium. In the wild, it can attain sizes up to 18″, but tank specimens rarely exceed a foot in length.
The Miniatus Grouper is a large and very hardy fish which requires a large aquarium of 180 gallons or more when full grown. It can be compatible with other fish provided they are too large to be eaten. It should not be trusted around invertebrates or small fish.
In the wild this reef predator commonly attacks schools of reef-dwelling fish. In the aquarium, freeze-dried krill soaked in Selcon, feeder goldfish, or squid are acceptable.

The Miniatus Grouper is a striking addition to my 200-gallon reef tank. It’s very active and shows great interest in feeding. I feed it krill soaked in Selcon daily and it stays healthy. Just make sure your tank is large enough and avoid keeping it with small fish.

This fish is impressive in size and appearance. It’s hardy and adapts well to the tank environment. I’ve had it for six months and it’s still active and eating regularly. I recommend only for experienced aquarists with large tanks.

The fish looks stunning in the tank and is a great centerpiece. I feed it squid and krill, and it’s always curious. It doesn’t eat small invertebrates, which is a relief. I’m happy with the purchase and would recommend it to others with large aquariums.
