ok so i was in petco today and the little tiger oscars they had in there had ALOT of red on them they were gorgeous, but i thought it was weird that oscars that little would have that much color (they were only like 2.5" at most) i heard somewhere that some sellers give oscars testosterone or some other kind of chemical/hormone to make the colors come out more, so my question is if i get one of these oscars and their colors fade could i expect those colors to come back once they matured?
