What is this?

[triggreef]

I keep seeing these sacks here and there. never saw it in any other tank I had. It just looks like a clear sack. no other way to describe it. barely able to take a pic. it is usually about 1 to 2 inches and suck to a rock, usually ends up floating away til it hits a power head. seen it about 3 times, once a month or so lately.

Do you have a wrasse in the tank? If so it could be it's mucus cocoon that it secretes to sleep in.

How about a full tank shot?

I have a cleaner wrasse. He's been in there about 4 months. There was another one of these sacks in there again today. I don't think I have seen more than I can count on one hand. I would think if it was something like a sleeping bag, I'd see it more often?

Other tank mates are 2 maroon clowns, falco hawkfish, flame angel, hectors goby, majestic angel, fiji blue devil. A whole mess of frags, Probably a bunch of no no's but spaced out very well.

Looks like a tunicate. But they are not usually clear nor do they regularly float away.
