The problem with disease IDs (in the same light I remember a sexually transmitted disease workshop they hauled us teachers into one time) is that they show the really terminal, well developed cases on the fish (or people in the case of that workshop).

Most of us will spot something on a fish or ourselves long before it gets very extreme. That may be why identification is so difficult.

And in the case of the images of Mycobacterial infections on those fish, they are "goners" anyway.

I think you are wise to be concerned asnd if it persists, get it checked out. The likelihood of you being infected is pretty small. If you were infected, the likelihood of you being cured, I would think, is very great.

I get cut, I clear out of the aquarium and wash the cut with hydrogen peroxide. Squeeze the would to get it to bleed a little and wash out the wound.

The library guy here has been very gracious in that I have exceeded my hour. So I need to sign out. Google GL for doppy uncle scott and fish TB and how I dealt with it. Mere neosporin probably will not do much for you if you were infected. It is worth a try, but clean up if cut and stay out of the aquarium until such a cut heals. I too have reasons to especially not want that stuff in an aquarium, both for the sake of the fish and me.

I guess it is a calculated gamble what to put one's hands in. I'm hypoglycemic and probably will have diabetes some day. (Sigh.) Two good friends in Chicagoland have to deal with diabetes and still keep fish. Attended the wake of another. His diabetes-related death had nothing what-so-ever to do with his fish, but probably his lifestyle and diet. It is your call.
