My clown have something like Ich but not ich
its like ich ,but smaller in size ,fade in colour ( not white can't be seen easily like ich),looks like cottony material
what do you think is that and how to fix it if its a problem ???.... i am giving garlic with food to my fishes .

If it is cottony, then likely it is a fungus. Where on the body is it?

all the body especially the head and middle body
