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.
