poor fish
The current tends to catch in their finnage like sails, and the weaker the fish is, the more pronounced the damage. A fish in a bowl tends to have less muscle tone, simply because they don't need to in a bowl. Be gradual with your current change. I've lost a fish in the past, by not being gradual with the current change. He didn't have a problem being in a bigger tank at all, but the filter at last did him in.
