So sorry to hear about endlercollector endlers having TB. Now that I saw your video in this thread, I'm wondering if TB isn't also what one of my snow white danios has. As endlercollector's video is the first one I've seen of TB, I thought I better post mine as well to get some opinions. [video=youtube;BC_DS9UV1gw]https://www.youtube.com/watch?v=BC_DS9UV1gw[/video] I've moved her into a specimen container and toward the end of the video I show the 29G tank of my other danios -- one of which is the last remaining of the 3 snow white danios I purchased several months ago. The first one also died in a similar fate that this one seems to be -- losing weight, not eating, getting gaunt, and its spine does look a bit curved. If it is TB, is euthanization the best option or are there successful treatments for it? Also, has any ever taken a sick and dying fish to a fish vet and had them run the tests for TB? How costly is that type of test and how do I find a fish vet locally? (I never knew there were such types of vets but I suppose it makes sense.) I know, I know, Google's my friend. I suppose I could just search for fish vets, huh? ;-) But if this test is likely a $100 test or more, it isn't going to happen, but for $25 I'd do it just to put my mind to rest.
