anemone?

[rubikcube]

I have a few of these anemone-looking things in my tank. I'm not exactly sure what they are. I have had the tank for about 4 months now with just regular normal output fluorescent bulbs. Definitely not enough light for an anemone. But these guys are just staying the same, except for one which is getting bigger. The tentacles are very clear with a white bulb on the tip of each one. I can't tell if it has a foot or not. Thanks.

pretty hard to tell from that picture.

from the looks, which it is kind of hard to see, my guess is aiptasia

Looks like an Astrangia Coral to me.

I agree it looks like astrangia or a close relative. Depending on the species, some are light demanding, some aren't. Good luck with them.

Thanks for the help. I'll see if I can get a good picture of the big one. It is on the back side of the rocks and difficult to get with a camera.
