Is this good rock?

[Van down by the river]

It is better than aqua cultured, although I've seen some nice aquaculture(Walt smith) I would buy it more for it's shape and conservation value than the organisms on it.

Ultra Premium grade:

- Good coralline coverage, polyps, macro algae, sponges and other beneificial organisms.

feather dusters are a given, and could have attached to the rock from their holding tank. sponges, polyps, and macro algae other than a sprig of caulerpa seem to be missing. I know that rock varies but when I think "ultra" I think of nicer rock than this.
