Queen Angelfish
Queen angelfish get their name from the "crown" of electric blue encircling a black spot just above their eyes. Their vibrant colors help them evade predators by blending in among equally vivid corals on Caribbean and western Atlantic reefs.
Junior cleanup crew
Juvenile queen angelfish feed on parasites living on larger fishes. It might sound daring, but it's a common symbiotic relationship on coral reefs: The small fish position themselves to advertise their cleaning services and other fishes line up. Cleaning stations are safe zones from predation. While the young fish get an easy, high-protein meal, their "clients" benefit from the removal of parasites on their scales and gills. Adult queen angelfish are omnivores, feeding mainly on sponges and algae.
