I can vouch for Richard and TBS rock, my 180 is done completely with his rock. I'm close enough that I picked the rock up so there was no die-off whatsoever but he does a fantastic job packing it and from all the reviews you see on it, there is very little die off upon shipping either. The rock is teeming with life ...... both growing on the rock itself and of course a bunch of critters, not all desirable. You will have to remove/trap some things out of the tank ..... gorilla crabs, mantis shrimp, whelks for instance. There are some very good shapes to the rock and they are full of holes (small fish and critters will go in a hole on one side and appear out the other) but they are a bit more of the 'boulder' look than some others. I am upgrading my tank right now and have ordered some manado rock to add to the tbs, i think this will allow a bit more creative scaping.
Richard is great to work with - check out his website or his forum and you can get a good idea of what his rock is all about.
When I started my 90 I went with the brs eco-rock - thinking I would try that to avoid hitchhikers and keep the price way down. Personally, I wouldn't do it again.
