Care

Caring for the Brown-marbled Grouper requires a spacious tank to accommodate its territorial nature. It is a hardy species that adapts well to life in captivity, provided that the water quality is maintained at optimal levels. A varied diet of meaty foods such as shrimp, squid, and fish flesh is essential for their health.

Reproduction

In the wild, groupers are protogynous hermaphrodites, meaning they start life as females and can change to males as they mature. Breeding in captivity is challenging and not commonly achieved by hobbyists.

Habitat

The Brown-marbled Grouper is found in the Indo-Pacific region, from the Red Sea and East Africa to Samoa, north to the Ryukyu Islands, and south to New Caledonia. They prefer reef environments and are often found in lagoons and on outer reef slopes.
