yes, running the antibiotic just in case, and I read that the sulfa meds are supposed to be highly effective against gill disease.
but this morning I awoke to a lethargic fish and then noticed this:
they are poor quality photos, but the one eye is starting to cloud over and there is something else going on in the lower left corner as well.
After I dosed the tank yesterday he began frequently flashing the one side against the glass and I noticed him pushing his eye in into his body against the glass several times also as well as a frequent twitching motion towards that side.
That is the enlarged side, the side that he was always flashing, and naturally at a loss for an explanation. Possible theory is that there are/were in fact parasites in that area which were affected by the fenbendazole and either exited the body and/or dies in the tissue. Hopefully the API Triple Sulfa will manage the cloudy eye, otherwise I will add a gram opposite antibiotic to whatever the triple sulfa is.
