Well, I have been treating my 2 clowns, two Chromis and Firefish for about two months now ever since they have had ich. I’m glad to say that the ich looks like it’s gone with no new spots appearing and only a couple of spots left. Unfortunately, the Firefish, (who I regret quarantining to begin with because he never had ich) has stopped eating and hides all day. I looked at him closely and on his side there is a reddish bruise forming. This really worries me because I love this fish. I immediately did a water change and I will do another one.
