To start, sorry for bad pics but this is toward the middle of tank and have to zoom in all the way.
I noticed the think on a rock of Zoas, it doesnt appear to move and has two mouth looking things and looks like a filter feeder but no clue what it is. tends to shrink down with shadows or fish swimming over. 3rd photo is it closed. Any help is appreciated.

Tunicate would be my best guess, and harmless. Actually a pretty cool hitch-hiker.

I second @Tahoe61 with the Tunicate and that is a pretty awesome Hitch Hiker. I have been hearing about a lot of cool Hitch Hikers lately!

Thank you both, I did a search and they come in some pretty cool colors, mine at this point isnt all colorful but will leave it be and see what comes of it.
