Here are a few things you should know to help you decide if a Koran Angel (Pomacanthus semicirculatus) would be a good choice for a 75-gal reef tank:

• As juveniles, their diet is mostly algae.
  
• At 6"-7" their coloration changes as they make the transition to adult coloration.
  
• Once they become adults, their diet changes to mostly sponges and corals.
  
• Their maximum size is approximately 16" which means they should have a really large tank.
