Rock flower nem and nepthea

[nshepard302]

I added a rock flower nem to my tank yesterday and it seems to have chose its spot overnight but has lost color in its center curious if this was normal or if there’s something I need to do, I also have a nepthea that’s been in my tank for a couple days now, I have it loosely held with a rubber band around my rock but doesn’t seem to attach and doesn’t look very healthy, am I doing this wrong, I’m new to corals and nems

I was also curious what kind of coral this was as it was given to me at the store with my nepthea and they didn’t specify and I had forgotten to ask

Might be too much light for the reck nem. Mine is in the sand at the bottom of my tank.
Your tank also looks fairly new judging by the rocks. Most people wait about 3-4 months before adding corals.
