one of my breeding mollies have been looking kind of odd lately.i have been feeding my fish on vipagran from tetra, but this particular safron molly seems to be having problems with his weight. he is thin around the base of the tail and there seems to be something on his body. it is almost like a white layer on his back, looks almost brittle like calsium. can anybody help me identify it and whether it is contatouis and how to cure it?
