I need help identifying these two guys. I got them on a few pieces of live rock i bought from someone that was breaking thier tank down a few weeks ago and I didnt even know they were there untill they moved around into the light. They like to close up at night but during the day the purple one with the green rim is giant, like 6" across and its moving a little close to my Zenia. I need to know if theres a danger of them stinging my other corals.
