From what Haiko (Stiffmeister, the previous owner of this fish) told me he had it happen a couple of times (by accident) and that afterwards the fish was laying on his back with a swollen belly breathing heavily for a I believe about a week.
damn that must have been horible for him to see. WHen I saw his other panaque when I picked up my juruense, I seriously fell in love. I think I might have cried if I saw that, let alone the person whos been caring for it for so long...
