Could it be fish TB?

This is the 3rd platy from my small tank now that I have euthanized as the spine went all bent and the fish became really hollowed out in the belly. They have fell sick maybe a month apart.

Really hoping it is not fish TB. I got a fish once from the store that soon showed the signs of bent spine and hollowing and got rid of him and hoped that it hadn't spread, but then later a healthy fish got that and so on. This is the third fish.

If it is how can I know? and also how do you disinfect everything? I cannot imagine ripping the tank apart and starting over. Besides the other fish seem fine. I am afraid I have used the same net in both tanks......

And I have read about the fish TB here, says that most of the time it starts as skin lesions. My fish only lost weight and showed a very curved spine. No skin lesions that I can see and they retain the colour ok.

TB is passed onto other fish when one dies and the other eat off the carcase. Unless that's happened, then I doubt it's TB. Bent spines can come from genetics and other illnesses, as well, but we just never know what the fish were subjected to prior to our purchase of them. How long have you had them?

Best to get fish that are ill out of the tank asap and not wait for them to die so you did good there.

Thanks Lady Hobbs. I got them out as soon as they looked sick and the spines bent. and humanely put them down. (froze them). No dead bodies were left there. I am fanatical about that. I feel so much better knowing it is likely not TB.

I have had the platys for 3 months only. The latest one to die was purchased about 6 weeks ago.
