Hi everyone. My tank is 75 with a 10 gallon sump. In my tank I have 2 clowns. 1 purple tang and 1 blue damsel. The tang has visible signs of ick and i removed him to a 40 breeder for copper power yesterday. This morning I wondered shouldn’t all the fish get the same treatment ? Originally I thought treat who is sick. But if they are all exposed. I should treat them all… Right ?
