Woke up this morning to find this on the side of my tank. I have no idea what it is or what would make this. My tank is FOWLR with cleaning crew, Lawnmower Blenny, Diamond Goby, and a six line wrasse. Anyone know what this is???

Just some hermit crabs and snails and one scarlet skunk shrimp. I have three different kinds of snails, I know one is a turban snail, the other two I'm not sure what they are.
i believe they are cerith snail eggs. not too long ago, I put about ten my my tank. A few days later, I had eggs just like the pic above.
some may hatch...some may get eaten.....others will grow to over populate your tank but in my opinion there is never enough snails...
