Common name: Rock cod

General information

The Wavy Line Grouper, scientifically known as Epinephelus undulosus, is a striking fish species admired for its distinctive undulated patterns across its body. This species is part of the family Serranidae, which includes groupers and sea basses. The Wavy Line Grouper is not as common in the aquarium trade as some other groupers, partly due to its potential large size and predatory nature.

Care

Caring for the Wavy Line Grouper requires a spacious aquarium, as they can grow quite large, reaching up to 30 inches in the wild. They need ample swimming space and hiding places to feel secure. Their diet should consist of a variety of meaty foods such as fish, squid, and crustaceans. It is important to note that they are predatory and may eat smaller tank mates, so careful selection of compatible species is crucial.

Reproduction

In the wild, groupers like Epinephelus undulosus are known to be 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 due to the large space and specific environmental conditions required.

Habitat

The Wavy Line Grouper is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They prefer reef environments and are often seen in lagoons and on outer reef slopes, typically at depths ranging from 2 to 40 meters.
