Hi, I have a big Entacmaea quadricolor in my tank since one week. It split the day after I got it so now I have two. 
The problem is that the two of them do not seem to settle. They walk all over the tank and seem to prefer dark places. At the moment they are both behind some live rock and I just see a few tentacles popping out. There is no light there and I worries about their symbiose-algea. I've read they need a lot of light so I piled up some rocks just under a reef-sun 50/50 light but they seem to hate light. Somethimes they do settle under that light but then they just walk away and hide again.
Are they sick? Is it normal that they hide when just split and still healing? Or do they just need to get used to the tank and all will be fine in a while?
My tank is perfect and very well balanced.
What might be the problem here? My problem with this is that I can't place the other corals as they are overrun by the anemones.
