pices usually has some interesting stuff in their pieces. i probably bought like 30lbs from them and i think i got like 2 or 3 mantis (i know i got at least 2; i was originally going for a mantis tank so i was happy... until the bigger one started breaking my corals to block his cave

), lots of crabs, feather dusters, etc. etc.
i was digging through the rocks just for fun a couple weeks ago, and saw about a 2" mantis crawling around. i was trying to catch him and poke him onto a smaller rock so i could get it but he got away.
i found a really unique piece from big als, but not much life on those
picked up a few rocks from red coral too. Nice pieces
