Description
The Blackcheek Threefin is a tiny, cryptic marine fish known for its excellent camouflage among corals and sponges. It is characterized by its three dorsal fins and often a dark spot or stripe on its cheek. These benthic carnivores are popular in nano reef aquariums due to their small size and interesting behavior.
