Glass Eye Squirrelfish - Heteropriacanthus cruentatus The color of the Glass Eye Squirrelfish, also known as the Dusky-finned Bullseye, changes through its life. Unlike many other fish, this fish actually becomes brighter in color as it ages. As a juvenile, the body and fins are covered in brown to red patches. With maturation the coloration changes to a bright red. The Glass Eye Squirrelfish may be housed in a dimly-lit, reef aquarium, although, it will eat serpent stars, snails, worms (including fireworms) and crustaceans, and requires a tank with plenty live rock with caves, overhangs and crevices for hidingË. It can be housed as a single specimen or in small groups if they are in a larger tank and introduced at the same time. Caution is needed when maintaining the tank due to their spines. The Glass Eye Squirrelfish do well in a larger aquarium with plenty of live rock and room to swim. A small group is suitable as long as there are adequate hiding places and space in the aquarium. It is a nocturnal fish, hiding while the lights are on and waiting for the cover of darkness to swim around in search of food. Maximum Size:
