Well, the big plec, the butterfly, the fighter, the shark and the catfish (which turned out to be a bumblebee catfish :? ) all went to MA today and I got a grand total of £5.50 credit for the lot! You'd never have guessed there were so many fish in the tank as most stayed hidden and the fighter and the butterfly stayed in the far top corner, but since the above fish have gone, they are a bit more confident. The corys are actually swimming about the tank now! Thanks for all the advice on making the decision (I'm still not sue on the clown loaches, but my husband really likes them so we'll have to see how it pans out...
