Geez NS, you got a serious pod population there! My blenny would be in heaven! I cant even get that many
pods going in my sump. I guess the lack of fish in the tank is helping that a lot.
Your rock setup looks good cool, but make sure those rocks are stable. Dont want them falling and squashing stuff. Especially once you get into corals.
I got 40 lbs of Keys yesterdfay from Liverocks as well. The rock is pretty nice, and heavily laden with brittle stars. I found 9 of them (2 were in pieces, may not live) and one of them was over 8 inches tip to tip! Since the only other star I have is a monster of a serpent (who will rush to me when he sees me and take food out of my hand, its cool!) all of them when into my 180 for cleanup.
I inspected every rock for mantis, but found none, little buggers are probably hiding really good. Had a couple of sponges, a small amount of macro algae growth, and a couple of encrusted clams. Worms and crabs galore, I swear the most fun is unpacking the box!
