One of y mollies appears to have cloudy eyes. He has also grown very huge and is now double the size of another molly bought @the same time! Also near the end of his tail fin it is oing a black colour around the rim. Do you know what this is?
Can you provide a pic? The cloudy eye could be bacterial or parasitic. The black coloration could be just that, coloration and the size could be the difference between male and female, could be a prg female, or it could simply be better at getting the food.
