Chilomycterus schoepfi, known as Spiny Boxfish in a fish tank
The burrfish or spiny Boxfish (Chilomycterus schoepfi) is a member of the porcupinefish family Diodontidae. Is a great species for large fish tank or an aquarium. I took this photo through a thick glass hence sharpness is not at its best, and I used two speedlights.
