It's a bit grainy, probably because the light isn't strong enough and needs a reflector, but I think I'm pretty much happy with this. I ended up just switching the filter across from my little 8g, which is already cycled, before moving the neons and the corys in with the White Clouds. I picked up the bopani root from a local garden centre for peanuts.
My 8g only has the snails keeping a couple of plants company, but it'll do as a QT tank.
I ought really to acknowledge the guys on Badman's fora (link on my sidebar), for all their invaluable advice and support. Being a complete rookie, I've managed to avoid a whole range of errors, and learnt at a rate that I simply wouldn't have done, without that assistance.
