It can sting corals. Can't remember the name of it though.

I had one in my tank awhile ago. Forgot the name of it. All I know is it can sting, bad!

pseudocorynactis sp. Mainly open at night and they do pack a nasty sting. Kill it if possible.

Ok thanks so much guys! I ended up moving my softies and removing the small rock that it was on! Can you also please help me ID this creature, I notice that I had two of them and now I got about 4 to 5...

I seriously hope its not Mojano as its going to be a pain to remove all of them. Anyway they all are sponge like, neon green and grow in a cocoon like fashion, hope you can see it in the pics.

Here is a better capture of it, and as you can see it doesn't need light as this is on the bottom of a rock in a cave.

when I kill aptasia I usually boil some ro/di water and suck a little bit up into a turkey baster and put the tip of the turkey baster right up against the aptasia and give it a good squirt.So far its worked every time.Hope this helps.

^ Thats what I used to do, works like a charm. I used boiling tank water though. Same difference.
