Can anyone ID this little guy?

Notice this guy a few weeks ago and he was completely transparent. Now he seems to develop a brown stalk and I spotted another one in a dark area of the tank under an overhang, but he doesn't seem to be doing so well.

This was my best attempt to get a picture. He is very tiny, about half the size of a single zooanthid polyp (closed and picture behind him). He has long transparent tentacles with white bubble like tips and a browning stalk. Doesn't seem to move much, if at all.

It is one of the tropical Corynactis sp. anemone. Common name is "Ball anemone". They are non-photosynthesis, cryptic, come out and feed at night. They reporduce slowly in a well run reef tank. Does not bother anything. Can be seen at night with flash light.

Thanks for the ID. This little guy has doubled in size and so has his buddy under him. Cool little things to look at. Any chance clowns will host the anemone when it grows to size?

No chance in the clowns useing that anemone as a host. They dont get very big and if a clown goes near it, it will prob just shrink
