That live rock looks pretty dead. Live rock is normally only good for a day or two, three at the _most_ before siginificant die off occurs
Also, that fact that the box did not smell is not a good sign. If the rock was full of life, there would be die off in shipping, and that die off should stink when you open the box after a week. It is quite likely that there was hardly any life on the rock to begin with, or that the shipping took so long, everything already died and the smell has already came and then left. Either way leave you with some good looking rock shapes that will soon be full of life from other things in your tank. I hate to be the bearer of bad news, but I would rather not get your hopes too high.
Still cure it though, it will just take a while for stuff to show out of the rock
I would not trust anyone that ships LR
via NON overnight and 2 day delivery. For $150 (or maybe a little more), you could have had 40-50 pounds of live rock overnighted to you from any number of places the specialize in live rock. There is some good live rock on ebay, but it is hard to trust feedback ratings as a sign of if the seller is good or not. I have a friend who is absolutely terrible at ebay, he ships late, screws up item descriptions, overcharges on shipping, he sill have 98% positive feedback because people are affraid to leave negatives (since he would then leave them a negative...).
Also, curing live rock should smell like nasty eggs from the die off. Fully cured rock should smell like seawater.
