Thanks for all the advice about my poorly fish, friends.
Things seem to be settling down with them now, and the poorly looking ones are now swimming about a bit more.
I have a bit more room in my living room these days, and could fit a bigger tank in. Perhaps a 3 footer? How long should I leave it do you think before putting the fish through that.
Reading chez's thread, it looks like it can be a pretty big job and they have been moved about quite a bit lately, and didnt do well after it, so I dont want to lose them all.
