I've just recently gained an apprecation for the larger marine angelfish. In particular, I like the Koran, the Emperor, and especially the Queen. My question is, how fast do these guys grow? I'm thinking about setting up a ~70 gallon reef tank in the near future. Obviously, the above mentioned fish will all out grow this tank easily, but it would be nice to know how long I could house them in this size tank. Also, if I end up getting one of these angels I will get the smallest juvenile I can find.
