Wierd creature!

Ok so I don't have any pictures and only a lame description but it's real- I swear.

 

I was looking at my tank today and saw this little thing pop out (like a toothpick sized stick). It then expelled a cloud of something (brownish but hard to say for sure under pure Actinics). It then went back in.

 

The best way to describe it is that it was almost like a Wack-a-mole the way it popped up and then back down.

 

As far as the cloud of stuff, it reminded me immediately of a cloud of ink from an octopus. There didn't appear to be any actual material in that cloud.

 

Any ideas of what I saw? Was it a aquatic Big Foot?

Sounds like a peanut worm. Cool creatures and nothing to worry about.
