Well, he remains the same - no better, no worse.

I did read something last about treatment for fish TB, IF that's what he might have. The article was suggesting trying Kanamycin and Vitamin B6 (baby formulation) for 30 days.

Have you heard of this treatment and of it being successful? If so, should I give this a go if he doesn't start improving in a few more days?

The only thing is I'm reading that along with the curved spine TB usually manifests itself with sores/ulcers and loss of color to name a few. None of these are showing.
