I really am starting to think it's a bully. This is only happening with my guppies. Today I was gone all day and all were fine, I was home for an hour and found one floating (sorry to be gross) but his eyes were gone. They have no other signs, there's no symptoms or warning. It's fast and quick. I have removed 2 fish that may be the culprit. The most aggressive fish in that tank now is an angel fish and she's small. Also as asked, they show no signs, eyes look normal, no black or white spots, no extra film on them, scales are as they should be. As for wiping it I use a fish only towel sometimes paper towel. I've researched and read allot and the only thing that makes sense is another fish. I will know within a couple days. I'm really getting frustrated!!!! And someone suggested using BW salt, problem is I can't find any. Ugh grrrrrr. Anyone?? Please feel free to offer suggestions or opinions. Note I do water changes often as there is so much death. I usually get them out quick but sometimes it's while I'm asleep. I check on them often like mother hen because I don't want a disaster. I am getting tired and afraid I'm going to give up even though I enjoy it. I don't want to keep killing gish
