That's really odd advice from a LFS
. They missed out on the opportunity to sell you many things! I mean... in my opinion, getting a quarantine tank is the "right" answer. So they could've sold you a quarantine setup, as well as the live rock. Guess they're definitely not out for your money!
But seriously, the LFS
's argument only makes sense if you plan on treating the fish in the main display tank. And they're right... if you did that, you wouldn't want live rock in there. If you were treating with copper medications, you wouldn't want sand in there either, for that matter. But I'm guessing you have sand?
