This is a Heniochus that I put into my tank on Friday. My One Spot Foxface didn't seem to like the new company and was going after him. I just noticed this today. He is eating fine but it seems like he may now have Ich as well. I can't catch him to put him into quarantine and as I have been trying, it is definitly stressing out my other fish. I guessing this is an open wound and my question is, will First Defense and/or PolyLab Medic help this situation. If not, what can I treat this with and slow down the Ich?
