I would get some maracyn plus, kanaplex, furan-2, or triple sulfa. All of those will treat both gram positive and negative. Out of the ones I've tried furan-2 seems to do the best. Kanaplex I hear is the best option though.
But if it really is fish TB, it's in curable and VERY contagious, everyone in your tank is likely to have it. You can either euthanize or let them live out their lives, but if it were me I would euthanize if this next round of treatment doesn't help.
Also remember that TB can stick around even after bleach. You will need a tuberculocidal disinfectant to get rid of it, something like barbicide plus which is easily available at Sally's beauty supply and at a good price.
