Hi Lorna
Yes, it is really sad. I did some reading, and found that if they have an upset belly, they do that. Could have been some bad krill possibly. He has been acting weird for the last week. Could also be that he ate a snail or crab, wouldn't surprise me. Thank you as well, Quaddity.
I just wonder why jump? It's not as if it is a better world out there.............
