sorry for your loss, but i have to aggree with the others.
O's breath through their gills and a mouth bulging with food will not block their breathing,imo.
Mine swam round with a too bigga fish stuck in his mouth, but couldt breath just as well.
my new tiger will eat lots of pellets and will take a feeder fish as well.
He'll be swimming round for a long time before he finally crushed all the pellets, to finish the fish after that.
btw we never look down on someone who does their best in the fishes interest and is looking for help. in the end that's what we're here for.
I'm pretty sure most of us lost fish due to various circumstances, i know i did.
Especially if you are willing to learn we'll be here to help you as much as possible!
can we see some pics of the new baby.
