What are these?

I know the first pic is of fecal matter, but WHAT leaves it? Has been in tank since setup with rock, and have not seen anything that can leave that big of a mess?? LOL. Second is like a 2 chambered heart attached to christmas tree worm, just curious.

First one looks like a peanut worm

Can't tell on second one. Could be a tunicate from the description.

the first one isnt alive, it just appears. I have tried to pick it up and it just falls apart.
