Need ID Help Quickly

[jgraz]

I was at the LFS yesterday to get some live rock. In the live rock tank there was a seperate bucket that the owner explained was recently dead or dying coral. I chose the following two pieces.

Now its clear to me that the sencond one is not dead. Both pieces looked like the first until about 30 min ago when i turned off the lights. Now one of the 2 has clearly puffed up.
What should I do?

that coral is not doing bad at all. it's a plate coral ?(Fungia repanda)

Ok well it seems like thats it. Now my concern is this. I was not expecting this. Im in the middle of a cycle, not high readings though. Will they be fine. I gonna move them to the sand bed. And they are in very low light. Right now only 15 watts for the whole corner unit. I planning on some new lights but it may be a few months. I was not really planning on corals, and just happened upon them in the live rock tank. Oh yeah, feeding help would be great.
Thanks
