hitchikers are a ridiculous reason not to get rock. Quarintine the rocks just as you would anything else (forgot to mention that, fishyman you'll need basic equipement for QT tank too. No one said this was cheap!) and any mantis, apistasia, whatever will be much easier to removie. Am I missing something here?
Orb: For the highest quality in both reef and fish, go with New world Aquarium. They are small for store standards (ny) and expensive (ny again). its on 38 and 3rd. There is a thread I started here about stores in the city, mostly everyone says just go to another city! they really dont hold up to most other stores, NW is still pretty nice to found your common stuff, in good quality.
