I believe it to be a nudibranch as I seen it on another frag of one of my zoa's. I tried my best to get a good picture

That's a Zoa eating Nudi, it's not a good thing and you need to remove it and check for others and eggs.

Zoo nudi get it out. Make sure to try to inspect other seven if you have to take all frgs out and dip them.

It's been out way before I posted this...it's a good thing I kept all my zoa's on a frag rack.i inspected each and every crevice of each and every frag plug containing zoa's.no eggs thank god!its pretty cool that they turn the color of whatever zoa they ate...kind of easy to spot under blue lights. LoL
