Common name: black soapfish

General information

The Soapfish, scientifically known as Rypticus saponaceus, is a unique and intriguing species that adds a touch of the unusual to any marine aquarium. These fish are known for their ability to produce a toxic mucus when stressed, which can deter predators and is the origin of their common name. They have a distinctive appearance with a mottled brown and tan pattern that provides excellent camouflage against the reef.

Care

Soapfish are relatively hardy and can be a good choice for intermediate to advanced aquarists. They require a spacious tank with plenty of hiding places and a stable environment to thrive. It's important to note that their toxic mucus can be harmful to tank mates if the soapfish is stressed, so careful selection of compatible species and regular monitoring is essential.

Reproduction

In the wild, soapfish are known to spawn during the evening, releasing their eggs and sperm into the water column where fertilization occurs. However, breeding them in captivity is quite challenging and not commonly achieved in home aquariums.

Habitat

Rypticus saponaceus is found in the Western Atlantic, from North Carolina and Bermuda to Brazil, including the Gulf of Mexico and the Caribbean Sea. They prefer reef environments and are often found hiding among crevices and overhangs during the day, emerging at night to feed.
