Check these out too:
(sorry had to make space for some new pic) coral frag holder (just attach frag to whole in the middle with ceramic glue)
(sorry had to make space for some new pic) clams holder
by the way, those background plates are actually quiet reasonably priced. Approx 350 Euro to cover up a 100 Gallon tank. That's like $500. You would have to spend the same (if not more) for live rock. (or wouldn't you?) of course the shipment charges would just kill you
Frag holder = 40 Euro
