The royal angelfish, or Holacanthus passer, is a sea fish with a dark body and bright yellow tail. It lives on coral reefs in the eastern Pacific Ocean and feeds on sponges and algae.
The royal angelfish differs from related species in its bright yellow tail and white stripe on the dark body. It is important for the reef because it eats excess algae and sponges, helping to maintain a healthy balance in the marine ecosystem.
Collects food with its mouth from reef surfaces.
Immature form that undergoes metamorphosis before adulthood.
