Hi Jana,
I bought one of their "cleanup crew packages" a couple years back and was quite pleased with my order (it was an order for Astrea sp. snails, Scarlet hermits, and a couple of Emerald crabs). Everything was packed nice, they threw in a lot of extra snails and hermits, all of which seemed to arrive alive and healthy.
I've since decided to stay away from Emerald crabs (the ones I had were picking off my coralline and taking chunks out of my SPS) and I actually prefer "Margarita" snails over Astrea sp. snails (Margarita's seem to do a better job and seem to stay off the tank walls).
Hope this helps, and good luck with it.
Thomas
