so I have been trying to identify all the things that have hitch hiked into my tank on my live rock, many interesting things have been discovered, including a colony of sunburst polyps (they glow in the dark!) but there is still this
polyp that i can't identify, it is solitary and green, looks kind of neon green in the dark, its tentacles look strangely kind of like the tentacles of a bulbtip anemone, with that the ends being inlarged. Do you guys have any idea what it could be? I'll try to get a pic, because i finally found it

but it doesnt take very clear shots... so yea thanks!
