Identification?

[Natterjak]

I just noticed some things on the glass of both my tanks, and I've never seen these before. Tried to take a pic, but they're too tiny - they're probably 2mm in length at most. They're oval shaped, and clear - in the middle is what looks like a bunch of small grains of sand. At first I thought it was just sand trapped in bubbles that got stuck on the glass, but when I reached in to touch them, they're solid, with a jelly-like consistency, and they're stuck at one end to the glass. Anyone have any idea what these are?

Do they have little forked tails when they move around? If so, probably flat worms, if not, no idea, sorry!

Nope, they don't move - just found out what they are, looks like they're nassarius egg sacs - never seen these before - funny that they're now popping up in both my tanks at the same time.

I think you are right about an eggs sack but not sure what off. Do you have alot of them? I am surprised your fish don't eat them....you have a wrasse?

Snails.

Yeah, nassarius snail egg sacs apparently - there's a bunch of them all over the glass.

Just a cleaner wrasse in one tank - my naso always eats the cerith snail eggs, but I haven't seen him go after these - they're a lot more disperse than the cerith ones though.
