Wow, quite a lot of advice there! Thanks folks. I think i'm gonna go for plastic container then into a bag to acclimatize etc. I was hoping not to take all the other stuff out as there are other fish in the tank and i didn't want to stress them either, but i guess sometimes fish just have to put up with a bit of stress for their own good in the long run, i know i do! Same reason i can't almost empty it.
There's nothing wrong with a 5" plec, we were all young once and if i can get him safely into his new home he'll soon be a monster too!
Julie - he was sold to me as a "Big Spot Pleco," but looks suspiciously like a common one to me...
Sorry the pics not very good, my camera's a bit rubbish, and he doesn't like having his photo taken! What veg will he like, and do i have to boil it fist to soften it or anything?
Nice fish there bolty! And Daz!
Thanks again everyone, i'll let you know how the move goes!
