I saw white spots on his tail for the past day and half. I have seen ick more than my fair share with neons in the past. These looked like ick. This morning I went to prepare for treatment and there weren't any spots at all. I decided to hold off until feeding time again to check his tail to make sure that's what I was really seeing. There are no spots left.
I think that I should not treat since there are no longer any signs of disease. Any suggestions? Should I treat? no body else is showing signs of anything going on.
temp is 75, ph 8-8.1, nitrite 0, ammonia 0, nitrate 10 ( but I did just put 5 new fish in on Sunday). Water was last changed 2/4
