Feeding varies depending on exact clingfish species. These seven are the only known freshwater clingfish. Sicyases sanguineus is a species of amphibious marine clingfish in the family Gobiesocidae. Flexor is a genus of clingfish from the family Gobiesocidae. Its general shape is rather similar to that of the two-spotted clingfish ("Diplecogaster bimaculata"). Apletodon incognitus is a species of clingfish of the family Gobiesocidae. Opeatogenys cadenati is a species of clingfish from the family Gobiesocidae. Modicus minimus is a clingfish of the family Gobiesocidae. Suggested common name for this species are the "pygmy clingfish" and the "seagrass clingfish". However, the teeth of clingfish vary extensively depending on species. Whether any other clingfish has toxins in its skin or mucus is currently unknown. In some species, cannibalism where a large clingfish eats a smaller clingfish is not uncommon. The sucking disc is also reduced in some deep-water clingfish species. Lepadogaster candolii, common name Connemarra clingfish, is a species of fish in the genus "Lepadogaster". In some, only young clingfish are obligate and gradually move away as they become adult.
