thank you very much this was very informative, i found out because i started really reasearching and showed a few pics of them at to a freind that owns a pet store and said my 2 of my girls are tee positive and my one albino male was a tee negitive but couldnt tell with the het striped male. and he said the one way i should had know was due to the price difference i paid for them. but from what it looks like i will need to make sure i have a bit more knowledge before i jump into the ball project.
