Found while moving

[MYTY1705]

I just finished moving the contents of my 55 gallon to a 29 gallon tank. While moving I found a crab I didn't know I had, cool but not the question. I also found something strange. It is a pink tube that braches out into two tubes. They are soft and retract to touch. Kind of leathery feeling. The sand you see on it seems to be glued there. I tried to brush it away and it would not budge. It stays out lights on or off. Any help would be appreciated. I know Fulff will help soon. Lets get some one to beat her to the ID.

Thanks

Looks like a tunicate. Pretty common hitchhiker.

I agree it looks like a tunicate.
