It all started with a huge NitrIte spike in my 46 gal tank. Fish got stressed out, got Ick. Isolated sick fish (two out of the five total in there) in hospital tank, cured ick, also ran preventive course of tetracycline. Got nitrIte under control, re-introduced the two sickies. All seemed ok, except for one of the sick fish, my white Koi, had an injury of some sort on her side that wasn't getting any better. I came in first thing this morning, and her eyes were bugging out of her head. The other fish seem listless, so I'm using maracyn two on the whole 46 gallons.
I'm also using melafix, and have been for a couple of days now to help the injury. I'm also on day two of feeding medicated antibacterial food exclusively.
Please help. Is there anything else I can do??
