Are you talking about the xenia? You might be referring to the two red/green mushrooms. They are really cool. Not sure what they are called. Picked them up at a fragswap in Houston awhile back.
I just grew there. I really like the way it looks. Try cutting a small matt of GSP and actually superglueing it to the back glass. I've heard that works.
will it work under water? or will i have to drain the tank alittle?
i have been fragging my GSP and glueing them to LR rubble....it grows so fast that i have been selling it back to my LFS and its been paying for everything in and on my tank :mrgreen: :evil:
