What the heck...

Was about to clean out the 1 filter on my small species tank (I haven't touched this one in several months) and I discovered what I believe is either an all-knowing, god-like brain watching over my fish, or, a sac of eggs. I've never seen a sac this massive before lol, it's bigger than the biggest snail in there!? Over 2"!
Which I would assume is a type of snail eggs because of it's location.

but here is what made me post on here..

I felt it.. rock hard.. so I thought it's been there for awhile. Maybe I had the water level maxed out at some point in the past, so they were laid at the water surface, but later dried when I lowered the water.
I broke it off, it fell in the water and floated.. so I picked it up to look at it closer, and within seconds, wherever I touched it the skin started to sting, almost like a burning/pricking feeling!??! I was like OWw mother****** what the??
It actually made the hair on my neck stand up.

Am I wrong in assuming it's eggs, not some crazy fungus growing on my filter?

it's an apple/mystery snail clutch. They lay them above the waterline. They require good humidity (but not submersion) to hatch.

Forgot I even had one in there like 3 months ago lol he would have been my first suspect. Took him out for being too venturous. I feel dumb now, thanks though.

Nice going Brhino.......I had no idea what it was but knew only it was eggs.

As for the feeling on my hands, is that normal, or am I allergic or something!? (Only known allergy is bee venom, which is decreasing)

never heard of anyone having an allergic reaction - no idea. I handled a clutch once and had no such reaction.
