Picked up a large frag of zoas...think it's on a muscle

[Irongills]

I picked up an awesome zoa frag today. I acclimated them and watched it through the evening. I noticed the rock they're on is a bit strange and doesn't really look like a rock.

Just walked past and it actually moved. Looked closer and it looks like a muscle, with a smaller one growing off it. The main one seems to be attacked to the rock frag I glued down, so that's good.

Anything I need to be worried about with this? Are they hard to keep alive? I don't want to lose the zoas. Pic posted

Hard to see anything in your pic. I personally would not worry.

Yeah I tried to get a picture that would show the slit where the muscle parts, none of the zoas can grow there, obviously. Need to figure out how to take better pictures with my LED lights on.

I bought a zoa frag that was on a closed clam shell and one day I noticed that the zoa moved when I put my hand in the tank and the clam had its mouth opened. Interesting things always happen and it amazes me all the time.
