Its a 55gallon tank, and doesnt have alot of hiding spaces, so it makes sense that they are stressed out a bit. It looks most likely that they are females with the one male Yellow. I can't see any colour in the others, and they tell me there are no colours on them nor any anal spots either. I think youve figured it out for me. The fry are only about an inch long right now, but Im curious how they may be coloured when they get bigger. I know crossbreeding is kind of frowned upon, but Im almost curious enough to take a couple off them just to find out what the colouring would be after a year or so.
