So I saw this in my tank

This was in my tank this morning about an hour after lights came on it was gone. Any ideas and not the snail

Kind of looks like hydriod but I'm no expert on those...

It could be a cup coral... but from this angle I cant really tell... try to compare what you see vs the pics for each on http://www.lionfishlair.com/hitchhiker.shtml and let us know what you think.

Some cucumbers have tentacle mouths, I can't tell from the picture, but could be. Especially if it moved.

It's so hard to tell in a pic you can zoom in on. My phone does that and it's annoying.
