Oh, OK. I wonder about the feeding/over feeding. Gosh I hope we didn't kill him by feeding him too much.

I've changed the water by 50%. It was warm in there, due to the warm weather and the water was cold so i tried to even it out a bit so as not to shock them. Oh, it sounds silly but i feel awful. I just feel terrible about leaving them for 12 days. I think if he's not better by the time we leave i may have to euthanise him. Because they all might die otherwise. Now i'm all sad thinking about that.

He's still lying on his side - but when i was changing the water he was swimming around in a spiral and he was donking into things. Poor little guy.
