Greetings! I am new here and I would like to present something that came with my tank. I have had my reef tank for almost 2 years now and it was just about 2 months ago that we noticed this thing growing in the tank. It was hidden next to and underneath the mushrooms that you see next to it. Can anyone please identify it? I have been checking online for what it could be, but I don't even know where to start. Thanks for your help.

Maybe you can describe it? or mark it on the picture? It's difficult to tell exactly what your asking about. (at least for me)

I'm sorry. It's the one left of center with the mouth that looks like a nipple. Since my post, I fed it silversides and it swallowed it whole. At the most I think it's an anemone, but what kind. Thanks.

ginpang is mistaken.

It is an Borneman's anemones or Phymanthus buitendijki. Very hardy anemonethat really pack a punch. They will sting and kill corals it come in contact with. I bough one 15 years ago for 10 dollars. Now I am trying to get rid of them from my 320 gal tank. They reproduce by fission and pinching. The top pinched off and float off to settle to a new place and the base grow another crown. They are nice anemone but keep them in check or you will be sorry.
I get rid of them by taken infested rock and put it in my dark sump. They will craw off the rock to the side of the sump to get higher. I just peel them off the side of the sump and throw them away. I consider them to be a pest. My LFS would not buy or take them back.

Thank you, OrionN. So far, we only discovered it by accident. It hasn't been anything but a hitchhiker. However, I will take your advice into consideration and keep it on a short leash. Now, is it wise to just take it off the rock manually and remove it?

 

[OrionN]

It is beautiful. Keep a few of them in your tank is fine but when you start to have more than 5 remove them as sell them off.

I've always liked the look of those Phymanthus. How large do they get Minh?

 

[OrionN]

The oral plate get to about 2.5 inches and the tentacles about 1+ inch. Total about 5 inches max in my tank.

At first I thought it was Bartholomea annulata but I think you got it right.

Thanks Minh.
