General information

The Red Grouper, Epinephelus morio, is a popular fish among aquarists who appreciate its striking appearance and interesting behavior. This species is known for its distinctive red coloration and spotted pattern. In the wild, it plays a significant role in shaping the structure of reef communities by creating shelters in the form of pits and caves on the ocean floor.

Care

Red Groupers require a large tank with plenty of space to swim and structures to hide in. They are carnivorous and thrive on a diet of live or frozen foods such as fish, squid, and crustaceans. It's important to note that they can become quite large, and their tankmates should be chosen carefully to avoid predation.

Reproduction

In the wild, Red Groupers are protogynous hermaphrodites, starting life as females and transitioning to males as they mature. They form spawning aggregations, and their complex reproductive behavior can be challenging to replicate in captivity.

Habitat

Native to the western Atlantic Ocean, from North Carolina to Brazil, including the Gulf of Mexico and the Caribbean, Red Groupers are found on rocky bottoms and coral reefs. They prefer depths ranging from shallow waters to about 100 meters.

Hobbyists should aim to mimic their natural environment as closely as possible to ensure the well-being of these fish in captivity.
