The Symphysanodontidae, the slopefishes, are a family of small marine fishes, with only the genus Symphysanodon.[1] Most are found in the Indo-Pacific, but three species, S. berryi, S. mona, and S. octoactinus, are found in the Western Atlantic.[2] They are found on rocky reefs at depths of 50–700 m (160–2,300 ft).


The largest species of Symphysanodon can reach 20 cm (7.9 in) in length.[2] Their bodies are slender and compressed, with blunt snouts. They are red, pink, oranges or yellow in colour. The caudal fin is usually distinctively forked. The dorsal fins have 9 dorsal spines and 10 soft rays, whereas the anal fin has three anal spines and seven or eight soft rays.[3]


These species are included in genus Symphysanodon:[4][5]
