Noticed my snail next to egg sac like object, but its below water and they don't look like the s I researched for a clutch to look like. Are these infertile eggs? Should I remove them or move them above the water line? New to snails . . .I know they can reproduce even when the lone snail, I had another snail a month ago (died), so I'm not surprised of the presence of the clutch, but I think it looks odd compared to photos of white round eggs. My snail is busy making another cluster . . .
