sailfin
Tropical tank dweller
A sailfin is a fish with an enlarged dorsal fin that rises like a sail—most commonly the sailfin molly, a popular aquarium fish, or the sailfin tang.
The prominent fin serves for display and temperature regulation.
As a modifier, sailfin describes any fish with this feature: sailfin catfish, sailfin blenny.
