Right. Update on the fish.... they've gone. But not down the toilet.
I felt a bit bad about it, despite it being the easy option, and took them to the park instead and dumped them in the pond with the other fishies.
To be fair, we've had the fish for a year now, but it was a pain in the arse when going away for the weekend and stuff, as I'd always have to get someone to come in and feed them.
I'm sure they're much happier now :-)
