heat packs kill fish? I got a fish order in and there was 1 bag with 5 doa ecpt for 1 fish he was still breathing but real heavy. He died the next day. That bag was laying directly on 2 heat packs. The other bag in the same box the fish were perfect. I always tape them to the top (lid)and have news paper inbetween the pack and the fish bags. They look like the regular hand warmer packs not the big 36 hour ones. Ever hear of this or had problems with this? Thanks
