Common name: highfin grouper

General information

The Spotted Grouper, scientifically known as Epinephelus maculatus, is a striking fish species popular among aquarists for its distinctive appearance and behavior. This species is characterized by its robust body, covered in a pattern of dark spots that provide excellent camouflage among the reef. Groupers are known for their ability to change sex from female to male during their lifespan, a phenomenon known as protogyny.

Care

Spotted Groupers require a large aquarium with plenty of hiding places to feel secure. They are carnivorous and thrive on a diet of meaty foods such as fish, squid, and crustaceans. Care should be taken to ensure that tank mates are not small enough to be considered prey, as groupers can be quite predatory.

Reproduction

In the wild, Spotted Groupers are protogynous hermaphrodites, starting life as females and transitioning to males as they mature. Breeding in captivity is challenging and rarely observed, as it requires specific environmental conditions to trigger spawning.

Habitat

Epinephelus maculatus is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They prefer coral reefs and rocky substrates, where they can find shelter and ample food sources. In the wild, they are typically found at depths ranging from shallow waters to about 100 meters.
