I have 12 neons and 2 angelfish (plus an algae eater approximately 4" long). My tank is 30 gallons in volume. I saw a really beautiful black angelfish in my pet store yesterday. And I am in love with it! Now I want to get it! I never had a black angel before. Will my tank be overstocked with 3 adult angels and 12 neons (plus the algae eater)? Will my 2 angels like the black one? Or does one have to have the same type of angels? What's more, that angelfish is a young adult (and it most likely wasn't raised with smaller fish therefore it is not used to them). How likely is it that it will eat my neons?
