Miniatus Grouper

About this fish

Miniatus Grouper is a predatory reef fish for the home saltwater aquarium, sold under the name Miniatus Grouper (Cephalopholis miniatas). It’s a bottom-to-midwater hunter that’s typically kept in a large fish-only setup because it will treat smaller tankmates as food. In practice, this fish is a great choice if you want a robust centerpiece predator and can provide ample hiding space and appropriately sized companions.

Features:

• Predatory temperament: will eat fish and crustaceans small enough to swallow
• Best suited to a large fish-only saltwater tank with plenty of rockwork for cover
• Generally hardy as a grouper/soapfish relative, but still benefits from calm acclimation and settling time
• Accepts meaty foods such as frozen silversides, squid, and shrimp
• Quieter, established hiding spots help reduce stress after arrival
• Choosing larger, robust tankmates lowers the risk of unwanted predation

Specifications:
