when I first got the zoas I noticed the one in the first pic but it was mashed and I thought it was nothing but over the months it has turned in to this thing with a sack and 2 mouths

you can see its mouth open. They will close up when I get near the tank but open up again in a few seconds

It's a tunicate, a harmless filter-feeder.

I wish it was one of the blue or purple kind.
