Description
The Opaleye is a temperate marine fish recognized by its distinctive bright blue or green eyes. Primarily an herbivore, it grazes on algae found on rocky reefs along the Pacific coast of North America. These fish can grow quite large and require a spacious aquarium with ample rockwork for grazing and shelter.
