What is this?

I found this today! A couple of days ago, it looked like silly string. Today, you can see through the casing.
All I have in the tank is a pair of false percs. hermits and some snails.

Any Ideas?

Looks like clown eggs? Of course, I am getting the visual from the Nemo movie. Very cool! Please keep us updated on what happens with this.

I would go with the clown eggs (fry) too. :D Not to sure from the pic though.
