I haven't heard of people testing water for TB but it could be possible. The main issue would be the small number of Mycobacterium cells in the actual water column. Normally they sink to the substrate or get sucked into the filter. If there were lots of infected fish in the tank you might get more cells in a sample of water but with only a few fish in a well maintained aquarium, they might be few and far between. you could try getting the water tested but testing a fish that shows symptoms is the best method.
If you can keep this thread updated then other people with similar issues might be able to use the information and I always like to hear how unusual fish things turn out, even if it's bad news.
