I seen these really beutiful gold mollies at maidenhead aquatics. I get most of my fish from there. These gold mollies were in a cramped tank. Most of them had black eye, others had normal eyes. There eyes were pure black, not a hint of white was left. One of them even had one black and one normal. My question is, is this normal. I asked one of the women there and she said it occurs normally. It did not affect the silver mollies. Please advise me as I really liked them.
