For $10 shipping, why not just order a small bit and see what you think. Is it Fiji rock or FL aquacultured rock?
I have gotten rock from liveaquaria, floridaliverock.com and liverocks.com. All was good. I got the most crabs and snails with the liverocks.com rock but I got more coralline algae and even plants on he rock from floridaliverock.com They came in the same box too
A friend of mine has reported tons of life on the fiji rock she got from premium aquatics. She has seen pods
, crabs etc. I don't think my fiji rock had hardly anything on it except coralline algae. We are in IN so premium aquatics ships 1 day UPS ground.
I like the diversity I have with my rock
