Hey, I have a 10g aquarium with 2 adult guppies, 10 feeder guppies, and 4 fry. The other day I noticed one of my adults had a white fleshy ring around its eyes and now her skin around her face looks like it's deteriorating and her mouth is offset. I put her in a separate breeding tank. This morning I checked my other fish, everything looked good. I checked 7 hours later and now my other adult has the thick white ring around its eye. Can someone please tell me what my fish have and how to treat it?
