I have what I always assumed was a zoa that was on the live rock when I received it. It doesn't have any tentacles around the outside of it and never closes up. It does phosphoresce under blue light. Is this a zoa or something else? Sorry, not a very good photographer and the weeds don't help.
Hard to tell but I have 2 thoughts acan but I don't feel to strong on that Or lobo which I feel a tad stronger on but not 100%
better pict gets better answers
