Hey there Otter,
Bent spine is common for fish TB.. some different things to look for include lesions on the body (little sores), other physical deformities, raised scales, and fin rot among other things. So your mix of symptoms can very well be fish TB.
Sadly, Kanamycin (Kanaplex) is the only drug that stands any hope of curing this disease. He will slowly wither away without. I'd suggest you keep him in the Kanaplex. He will be sort of lonely, but it's best to keep him separated for now in a comfortable habitat.
Are the other fish all healthy?
I would also suggest finding another location to purchase guppies at, or avoiding them entirely if this seems to keep happening.
