I take back my earlier statement. I was looking primarily at the second pic. The first pic does indicate that the ends of the tentacles have the bulbous appearance of a bubble tip. I've seen a lot of stores advertise various anenomes under the blanket term "LTA".

looks very much like a long tentacle anemone.. the red column/base is associated with LTA's
The fact that it's not having very long tentacles may mean that it's not very healthy or water conditions are not great....
My clown's have stuck to my LTA's like crazy...
