Unknown Pattern Left on my Glass - Identification?

[sgrosenb]

I found this pattern of "goo" left on my glass this morning - I've never seen it before, haven't added anything to the aquarium lately, and my tank has been up for about 3 months. Anyone know what this might be from? Thanks!

Some sort of snail eggs. I am thinking either a Nass or cerith.

I second that I get them on my tank glass all the time. They appear and then disapear. You get diff patterns for diff snails too. I usually see three diff ones. Ones for my nassarius, turbo, and cerith.
