Hi Thomas,
I've over by London Bridge - I have about five LFS which I can get to quite easily. I occasionally see the Zebra but have never seen the threadfins. I got the zebras from TriMar to make up a slightly larger order as I really really wanted a pair of the scarlet badis that I have never seen anywhere round here.
Which part of this marvellous city do you hail from?
Cheers, Eddie
