Additional information:
Occur in lagoon and seaward reefs from 3 to at least 100 feet, on heads of small branching corals, e.g. Stylophora, Pocillopora, Acropora (Ref. 9710). It feeds mainly on shrimps, small fish, crabs, and other crustaceans. When a prey ventures close enough, the Arc-eye Hawkfish will make a quick dash and seize it.
This species come in a wide range of color variants, but all specimens have a distinctive ring that consists of three thin lines extending around and behind the eye. Some of the most commonly occurring color variants are light brown, deep red and orange. A white to pink stripe is often present along the lateral line on the rear of the fish. Each dorsal fin spine is tipped with a cirrus. Lacking a swim bladder, they spend most of their time perched on corals, watching for prey.
A 30 gallon or larger aquarium provides a good environment. Provide lots of rock work and branching coral to perch on and as territory. The Arc Eye Hawkfish should ideally be kept in temperatures between 72F and 78F. A pH value of 8.1 to 8.4, and a specific gravity of 1.020 to 1.025 should be maintained.
