General information

The Six-line Soapfish, also known as the Sixspot Soapfish or Goldenstriped Soapfish, is a distinctive and attractive species that adds both color and character to a marine aquarium. Its body is pale to white with six horizontal black lines that run the length of its body, interspersed with vibrant yellow to gold stripes. This fish is a member of the family Serranidae, which includes groupers and sea basses.

Cephalopholis sexmaculata is known for its unique defense mechanism. When threatened, it can release a toxic mucus from its skin that deters predators. This soap-like secretion is where the common name 'soapfish' originates.

Care

The Six-line Soapfish requires a well-established aquarium with plenty of hiding places and a stable environment. It is a hardy species but can be sensitive to changes in water quality. A varied diet of meaty foods such as shrimp, squid, and fish flesh is essential for their health. It's important to note that their toxic mucus can be harmful to tank mates if the fish is stressed, so careful selection of compatible species is crucial.

Reproduction

In the wild, soapfish are generally solitary except during spawning. Little is known about their breeding habits in home aquariums, as they rarely breed in captivity. However, they are oviparous, with females releasing eggs that are fertilized externally by the male.

Habitat

The Six-line Soapfish is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They prefer reef environments, often hiding in crevices during the day and emerging at night to feed. They are typically found at depths ranging from 4 to 60 meters.

Hobbyists should replicate their natural habitat as closely as possible, with a focus on providing ample rockwork and crevices for shelter.
