Does anyone know about Rams (fish not snails)? I got two of them and everything has been going okay except trying to stay away from the crayfish and I noticed that the littler one has lost almost all of her(?) black. She had a black spot on each side and one thin stripe through her eye and a lighter one behind that. she was even getting a rosey color on her tummy and a few bright blue scales. Now it's almost all gone. I'm not sure what to do. The bigger one was getting lots of orange and black and scales of blue and purple. He is starting to loose some too. He still has the black spot and some orange but his stripes are now fading. Not sure what's going on? ???
