Electric daisy stylo

[Alistar81]

Do electric daisy stylocoeniella have sweeper tentacles? I'm not sure what is on the top of my coral Could it be algea or just part of the coral? These are the best pictures I could get

Tough to tell from the pic but it looks more like a bare spot where some stringy algae has taken root.

I have one that has thrived for over a year. It was a frag starting to overgrow the plug when I put it in. Now it's a colony about 5" in diameter all over the rock. I have never observed sweeper tentacle on this coral.
