Maybe i'ts me, but I don't like fiji rock...it looks unnatural, more like iron rebar that's been encrusted with some crud.
I was super pleased with my order from liverocks.com
Just got 40lbs of keys rock last week and had soem brittle stars, crabs, some tiny shrimps or something...some tiny feather dusters...a few bristle worms....possibly a mantis shrimp (something in the tank or the tank itself is making a clicking sound....) and some weird clam/snail thing that occasional opens up.
and to think they warned me that the keys rocks isn't nearly as 'alive' with critters as their gulf rock!
