Common name: Red-flushed rock-cod

General information

The Redmouth Grouper, scientifically known as Aethaloperca rogaa, is a striking species known for its robust body and distinctive coloration. It exhibits a deep brown to reddish-brown hue with a lighter underside and a characteristic red mouth, which gives rise to its common name. This species is not as common in the aquarium trade as other groupers due to its size and territorial nature.

Care

Redmouth Groupers require large aquariums due to their potential size, often reaching up to 50 cm in length. They need ample space to swim and territories to claim. These fish are carnivorous and require a diet of meaty foods such as fish, squid, and crustaceans. It's important to feed them a varied diet to ensure proper nutrition. Due to their predatory nature, they should not be kept with small fish or invertebrates that could be seen as prey.

Reproduction

In the wild, Redmouth Groupers are protogynous hermaphrodites, meaning they start life as females and can change to males as they mature. Breeding in captivity is rare and challenging, often requiring expert care and a very large aquarium to simulate their natural environment.

Habitat

The Redmouth Grouper is found in the Indo-Pacific region, from the Red Sea and East Africa to the Central Pacific. They prefer reef environments, often seen in lagoons and on outer reef slopes, typically at depths ranging from 2 to 40 meters. They are solitary and territorial, often occupying caves and overhangs as their home base.
