Leslie, that shroom has been evasive since I put it in my nano. I can't get a decent pic (bowfront tank :grumpy: ) to save my life. That 'accidental' pic is actually the best I've gotten. It is green and the polyps are about 4" in diameter. You can see they are bigger than the lionfish, and he's about 2.5".
I have three color morphs of these guys including the one on the pic! I will post pics when I get back to NYC next year (Jan 2nd! LOL)! I'm in Miami right now, and you bet your butt I've been going snorkeling and diving
best,
L
