Possible eggs on glass?

[anthonys8107]

I am attaching an image of something bizarre I found on my tank glass. I have never seen something like this before and am worried that they’re some sort of eggs or invasive species. What are they and what should I do? We have turbo snails
nassarius snails
fire and cleaner shrimp
vlamingi tang, powder blue tang, sailfin tang, kole tang
foxface rabbitfish
2 clowns
coral beauty angel fish
melanarus wrasse
skunk tile
5 bar gobies
I’m thinking the snails are the culprits but I might be wrong.

Alk 10.4
Cal 410 (working on increasing)
Magnesium 1300 (increasing)
Nitrate 6.8
Phosphate 0.03
SG 1.026

You're not wrong, those are snail eggs for sure.

Snail eggs!

Should I try to scrape them out or let nature run its course?
