That's where I got mine too. I didn't get overnight which I regret. It would have doubled the cost though. And UPS was late, I lost a tiny crab, cucumber, and starfish that I know of.
I have 1 definite coral coming back(possibly rose coral), maybe another 2(star corals). Macro algae out the wazoo! Finding more bivalves. I removed some sponges, still have a lot, Tunicates, lots of pods.(one light bulb anemone who shall live for now)
Only negative is I found 3 Cirolanid isopods, they have the large slant eyes and don't roll into a ball. I found them in my overflow chamber. If you want to set a trap for them there's some info in R2R.
Overall I wouldn't hesitate to do it again, take the good and the bad with live rock any day. Hitchhikers can come from anything we put in our tanks anyways.
I hope you keep finding more goodies!
