I've seen tanks with montipora that has grown to and encrusted on the glass walls. I'm interested in doing something like that, except starting on the glass. This is a lower light tank so I'm think Leptoseris, Lithophyllon... wondering if I could do it with Chalice? Any experience? Suggestions? My frags are small for now so I think glue will hold until they grow off the plug to encrust themselves onto the glass.
