Too soon for corals??

I have a 30-ish gallon nano tank with a 30 gallon sump set up with an octopus reef skimmer that I put freshly mixed R.O. salt water in with one bag of carib-sea aragonite live sand to start cycling almost a week ago. yesterday I purchased live rock from a guy that was dumping his tank for a big move. It was a great deal and couldn't be passed up! however, some of the rocks still had corals attached to them. There is two different kinds of xenias, some green polyps and mushrooms, a ricordea and some zoanthids. Naturally, I already have all the rock spread out between my tank and sump. But since my tank has only been cycling for a week should I take all the corals out? the polyps are open and the xenias open and almost pulsing, the ricordea seems to situating himself just fine as well. I do have a lot of water from this guys system that I also dumped in my tank as well which could help them. Also if its important I'm cycling my tank pretty naturally, I basically just put the live sand, the live rock and the existing system water from where I got the rock in the tank and just gonna let it do its thing for 2 or 3 weeks and start putting snails and what not... but idk what to do about those corals on the rocks, any suggestions?

 

Since you used live sand and live rock on which the corals survived, there's a strong chance that your system is seeded and won't actually see the typical "cycle". You look like you're on the right track-- wait 2 - 3 weeks, then test your parameters. If everything is in check, add additional livestock slowly.
