Some years ago, I remember reading in Aquarium digest that Bitaeniata, I >think they were still being called Kleei at the time, will throw both >red and blue individuals in their spawns. Perhaps this is also true of >Bitaeniatas. A. bitaeniata are extremeley variable in nature and in captivity. If you look through a large Peruvian importation you will find much individual variation from the bold and beautiful to the homely (remember some sneaker males look almost like females). I'm not sure if I agree with Romer's statment though about agassizi. There has to be some regional population variation. I've never studied them in the wild, but from the commercial imports the wild morphs aren't that variable (e.g. you will never see red, blue/white and Rio Tefe from the same collecting locale).
