Blennies
Blenniidae
Key differences: Blennies typically have a single, long dorsal fin (though some have a notched fin), and their pelvic fins are small and separate, not fused into a disc. They often have cirri (fleshy filaments) on their heads, which are generally absent in gobies.
Dragonets
Callionymidae
Key differences: Dragonets have a flattened body, a small mouth, and often elaborate dorsal fins. Their pelvic fins are separate and thoracic, but they do not form a suction cup. They also possess a preopercular spine, which is absent in gobies.
Sleepers
Eleotridae
Key differences: Sleepers are closely related to gobies but lack the fused pelvic fins. Their pelvic fins are separate, though often close together. They generally have a more robust body shape than many gobies.
