I have now ordered several groups of stock from here (cleaning crew, puffer, more cleaning crew when the puffer had some of the crew over for a "midnight snack", and most recently some corals). The drip-method they give here works wonderfully, and the tying the knot in the tubing worked great for me. And the fish/snails/crabs/corals that I have gotten have been in better condition than what I have gotten in the past from the area fish stores here. The puffer I got, in particular, was beautiful, it really pained me to let him go. Trust me, you'll love what you get.
