Just showed up one day (pic)

Sea Nut, I have that exact same look red anemone in one of my tanks. I've never been able to figure out what it is. It's been there for nine months. It moved once to the top of the live rock and then moved down onto a sea shell and has remained there. It has only been one for a long time. It has become considerably bigger now - about 4 inches high. I just figured because it didnt spread it was a "good" type.

In fact, my elegance coral attacked it and so I moved it away. I suppose a good way to kill them is move there rock around Elegance coral - they have powerful stingers!

Looks kinda like a green tip anenome? I dont know much, but i just got some rock from someone and they said the anenome's are green tip ones...the tenticles look kinda like it... all in all i have no idea! id like to find out though.

My instant reaction with your second pic is an orange ball anemone which is actually a type of mushroom coral, but has a very intense sting for a mushroom. I have one that is so far not a problem, but have heard that when they reproduce, they do it like crazy all over the gravel which will limit and irritate many or your animals.

I had one about a year ago about two months ago they started to reproduce and I started to fight back but with no luck now they are eveywhere even on sand and glass and they are killing my Zoa's, unlike yours(deepbeneath) these are small andl ook like Zoa's
