I find lots if thin branches and join them together using electricians cable ties.After that I attach them to the tanks brace bars.This way they hang down into the tank and look more natural.yeah that's another superb biotope! I'll do a little research, I'm going to be around Galloway Forest in the near future; hopefully I'd be able to find something. I'm very keen on the spidery wood that looks like its extending down into the tank, right now the wood i have is the solid driftwood, and it just kind of sits plonked on the bottom :/
