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.

A 75 gallon or larger aquarium with plenty of live rock and room to swim is needed. 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. It will eat invertebrates such as worms (including fireworms), crustaceans, and serpent stars.

Its meals should vary between live feeder shrimps, freeze-dried shrimps, and chopped marine meats that will move in the water column.
