Hello guys. I have two fantails. One of the goldfish is sick i think, the symptoms are white-gray spots on the body(they are invisible when its evening and the light is turned on, i will try to make better pictures tomorrow morning). I think the illness is not ick (or ich).
The fish swims quite often in really weird style, two days in a row the fantail was staying at exact same spot. The guy constantly rubs its body to the plants and the rocks. Can you suggest treatment.
Oh and also i bought them (the two fantails) at the exact same time, they were same size, but now the one is freaking large and the sick one hasn't grown up a bit (maybe a little), is this normal?
