I have a Emperor Angel about 5 years old, just noticed it got pop eye some how. its been 5 days now. The next day after I found it I went to the fish store and they gave me some antibiotic (amoxicillin) which has a dose every other day, have a supply for 4 doses. They also told me to turn my protein skimmer - dont know why, and add some extra aeration, but now my water has a green tint. I at least want to turn my skimmer back on.
Fish is just hiding in the back corner in my rocks, but he does come out to eat however very timid and picks up the small scraps instead of attacking the food as he used to. Starting to throw some food back in the rocks for him to hopefully munch on by himself. Other fish are doing just fine. How long will this last, am I treating him right?
I assume I should do a large water change but maybe after I finish the amoxicillin? Ok to add prime to keep the water clean?
I can include pics if anybody needs to. Any help would be great, feel really bad for this guy.
