Autopsy help

Whats up guys?
I just bought 6 green barbs (puntis semifasciolatus) from a lfs and one died overnight. It looks like his bladder busted out of his side. Does anyone know what could have caused this?

Did you dissect him? This is the only way to tell what has pushed through. Swim bladder sacs are dorsally located unless they blow up to an extreme and fill the entire body cavity.

I wanted to dissect him but I don't have proper tools. I just hope it doesn't happen to the others. I love the green barbs
