Oh no... I'm so sorry, Debs!! image

We can never absolutely confirm fish TB unless a necropsy is performed and tissue is sent to a lab for analysis. Some vets will do this. Other than the curved spine, what other symptoms did they ALL have? Typical other fish TB symptoms include fading colour, wasting away (anorexia), listlessness, loss of appetite, as well could be accompanied by pop-eye, fin loss, distended tummy and ulcers (that won't heal). We indicated before that fish can display a curved spine from being ill in general.

How many fish do you have now... and how many tanks? It is and will be important to not cross-contaminate between tanks... b/c if it IS fish TB, or another type of viral infection... it can spread easily... and you would have to assume all your tanks are infected. If you don't think cross-contamination is a factor... then you should ensure you won't cross-contaminate in the future by having separate equipment (cleaning equipment) for each tank. And we also don't recommend getting new fish as they could inevitably be exposed as well.

Again... I'm very, very sorry for all your losses... it's heart-breaking and very discouraging.
