all the water parameters were right, and all of a sudden hes got an ich-like parasites, it is not ick because he does not scratch, and it doesnt look like ich, it looks like as if some one painted white dots on its body, but they are pretty small, like the ich size. nitrates are below 40 or 60, nitrites are 0, theres strong current in my tank, and the temp. is 79F. this is what he is doing: swims a bit then he goes and lays in the gravel like a statue, like as if he was sleeping, then after a minute or so, it slowly wakes up and swims again and then it goes back to statue mode. it looks like as if he was really tired and falls asleep as he swims, but i know he isn't. like i said it is not ICH, his tank is 55 gallons
