Once again, thanks to all of you that have added your advice, it seems that I have been grossly mislead by my LFS owner when I bought my fish.
I'm afraid Dman that I already own clown loaches in my 12 GAL tank, but luckily for them I actually care about my fish (not like the money grabbing LFS) and will upgrade as soon as possible to accomodate their growth and well being.
Hopefully if I do this within 6 months it won't be too late, otherwise I'll do the right thing and take them to a reputable fish shop.
Thanks for the advice about the Bristlenose, I'll look out for a handsome chap to join my tank.
It looks like I still have lot's to learn so you might see a bit more of my now humbled self!
Once again, thanks.
Mike
P.S Can you believe that I actually first came on here to enquire about how red crabs would get on in my community tank, hence the name! LOL
