The Blackedge triplefin lives in the reef-associated, marine, depth range 15 - 15 m environment.
Blackedge Triplefin (the only other triplefin with a first dorsal taller than the second) are not reported in the Caymans. I would guess that that picture was taken in 20-40 feet of water. They are mostly frequently sighted on brain and star coral heads. More
