Unknown critter

Any ideas what these might be? They’re attached to the glass, and there’s also a couple on the underside of a frag plug…

Looks like ghost flat worms, I cannot confirm good or bad cause i do not know @ISpeakForTheSeas is good at critters

if it helps they’re stationary, attached to the glass and about the size of a tomato seed, they’re also more of a tomato seed shape/flatter rather than round

They are eggs of a type of snail, i have them also, I'm not sure the species but the snail that lays them looks like a type of cerith.

Snail eggs would make sense to me, though I'm not familiar with these eggs. Any pics of the snails?

Really does look like snail eggs, but this encapsulation is new to me.
