swim bladder disease

[elaine5182]

Help....
I've got guppies and danios in my 60l tank. I've lost 3 guppies in the past due to swim bladder.
My guppies are swimming erratically and their bodies look like their bent in half.
Is swim bladder infectious and after losing 3 guppies to swim bladder before and one having problems at the moment am I likely to lose them all?

This does not sound like swim bladder to me(it's not contaigous either) but rather sounds like TB, sorry to hear that this a tough one I'm afraid.
