Late last year I posted a thread regarding my African Knife Fish. One day he was fine and the next day I noticed his eye was extremely cloudy and where the pupil was there was a red spot that was like blood. All my other fish were, and continue to be, perfectly healthy. After coming here for suggestions, I removed the Knife to an isolated hospital tank and took him through two treatments of Tetracycline under the suspicion of him having Cloudy Eye or Pop Eye. The treatment didn't seem to do much.
His eye is no longer cloudy and it no longer has the bloody spot in the center. However it is dark colored and doesn't look like his other eye at all. My friend described it as looking like scar tissue. It is not protruded any.He does still have his eye. Due to his behavior when I'm cleaning the tank or when he knows I'm there, I'm under the suspicion that he can no longer see out of that eye. Whenever he knows someone is there he always turns is good eye towards the person or object in the tank and doesn't like anything getting on towards his other side with the bad eye, though I know Knife's are supposed to have bad vision in the first place.
But were do I go from here? Was he misdiagnosed and has something else? Do I need to try another form of treatment, or is it possible his eye became injured somehow, causing the cloudiness and bloody red spot. A side note of my injury theory: In the community tank he pretty much lived 24/7 in a plastic log with a Sailfin Pleco. I've heard that plecos have sharp spines on their dorsal which they will erect if they feel threatened. I don't know if its possible if the Knife got in a fight with someone else in the tank, tried to eat a smaller fish of mine that fought back, or plerhaps startled the pleco and got nailed.
It's actually my friends fish that she has in my tank, and she wants me to put him back in the big tank with my fish right now, but I'm a little hesitant since his eye doesn't look normal.
I'd really like any opinions on what you think this could be and what my next step should be.
