Thank you guys. I forgot to mention, the Nep is in a small pot :P. I also dug in around he sides and removed some of the sand and the little that was left, I then worked into the expanded clay at the bottom and some into the mix. I know what you mean about the green stuff on the moss being Alage as I use to keep and breed tree frogs, but this stuff grows, then puts up little pollop tendrils. I cut a few off and put them outside with my few highlanders, Sarrs and Dio, in a tray of finely cut up spag and sure enough, it started to spread. It was really slow at first, but now it's like wildfire.
