Genus
Common name: Longfin Dartfish
Scientific name: Oplopomus
Oplopomus is a genus of marine fish known for its elongated body and the strikingly long dorsal fins characteristic of the dartfish family. These fish are popular in the reefkeeping hobby for their peaceful nature and unique swimming behavior. They tend to hover in the water column and dart back to their burrows when startled. Oplopomus species are best kept in aquariums with plenty of hiding places and a sandy substrate to mimic their natural habitat. They are generally reef-safe and can coexist with a variety of other peaceful marine organisms.
