Unknown object in my 25 gal tank

[perocchit]

I came home after being away for a couple days, had family come by and feed everything once a day. This is on my glass, no idea what it is or if it is harmful. It stays in this spot, anyone recognize what this is? You can’t tell in the picture but some parts of it are not stuck to the glass and moves from my wave maker, however about half of it is still and acting at points of contact to prevent it from leaving the glass. The quality picture isn’t the greatest either because my phone camera wouldn’t focus, but it’s almost like a continuous, long squiggly white/clear line.

Snail eggs

Thanks, I will start looking into them then. Am I gonna have to put a bunch of small shells in there for them?

Nah, they either don't hatch or hatch and get eaten. If they make it, they have their own shells!
