im treating with ich-x. This started probably about a week ago when one of my clowns wasn't eating. For 2 days it did not eat and it had a white spot. After 2 days it resumed eating as if nothing happened and then when I got home from work i noticed more fish had some spots and the clown was getting worse in terms of spots. I'm not sure if to keep treating for ich or if too try another remedy. Help please!!
