My young guppies in my 10 gal have a weird fungal infection. They have cottony spots all over their tails and bodies and wherever the spots are, the color on the fish turns yellowy. I was away for five days so I'm not sure how this started. My fish are between 1-5 months in age. I was a little apprehensive with treating them since they are so young. I added 3 tablespoons of salt last night and today I added one dose of Marineland Ick Remedy; it treats ick and fungal infections. I have 40+ guppies in this tank and at least 10 of them are affected.
