Genus
Common name: Black Clingfish
Scientific name: Phaeoptyx
Phaeoptyx is a genus of fish within the family Gobiesocidae, commonly known as clingfishes. Members of this genus are notable for their ability to adhere to various surfaces using a specialized suction disc formed by the fusion of their pelvic fins. This adaptation allows them to maintain a strong grip even in turbulent waters. They are small, typically cryptic fish that can be a unique addition to a peaceful reef or species-specific aquarium. Hobbyists should provide ample rockwork and crevices to mimic their natural habitat and encourage natural behavior.
