HELP ID - Found critter in my Zoanthids

[Marcus8675]

It is orange, has 2 tubular holes. Hard outer shell. currently have 3 in my Zoathids. Thought it might be a sea squirt but not sure. Is this a good thing or a bad thing.

Seems to be some type of tunicate.

I did some research (google is a wonderful thing) and that sure looks like it. I have 3 of them in my Zoanthids. Still not sure it is a good or bad thing but I will keep an eye on them and see what happens. Thanks
