Weird goo sack

I have non idea what this is. I have a pair of clowns, bunches of large snails and a variety of corals. Is this a spawning sack of some sort? Should I remove it or see how it plays out?

 

Do you also have a Six Line Wrasse? Or Bubble Algae?

 

I have a leopard wrasse.

 

Your Wrasse type makes a cocoon and sleeps in it.

 

That's so weird! I usually see him dive into the sand to sleep. I have never seen him do that on top of the sand bed. Totally hope I get to see him come out of that!

 

I am going to double check with Hunter regarding this particular type of wrasse, some sites say they do make a cocoon and some sites say they do not. I know 1st hand that 6 lines do and other wrasse types, but I will double check.
