What is this?

Found this on the glass of my aquarium today. Never seen one before. Looks like a worm of some kind. It is definitely cleaning the glass around it.

I wonder if this is a time-of-year thing. I had the same thing last week.

yep, snail spawn. the fish will eat them, most likely. If not, you'll have millions of baby snails keeping the tank clean.

Could be timed around the full moon.
