What is this?

I have a 10 gallon reef tank and i have this new fellow and i don’t know wat they are. i got it first from some algee and i thought it was sand or soemthing and then it started to grow in size from an inch to maybe half an inch.

It appears to be a tunicate, but hard to tell in the photo.

Does it look like the below pics? (In the last pic, ignore the colonial tunicates, the orange tunicates are what I am referring to for comparison)

There are a few I have. They are filter feeders and of no harm to a tank. I cannot remember the name of them for the life of me right now, but will look at may notebook and dig up the name.

My vote is a tunicate also.
