What are these?

I have what appears to be eggs on a piece of petrified wood in my tank. They have been there about 10 days now and I haven't seen any change/hatch. Can anyone identify this?

The tank contains: male betta, a cory, hatchet fish, african dwarf frogs, neons, celestial pearl danios, amano shrimp, mystery snails, and nerite snails. No one seems interested in eating the "eggs".

I've ruled out the betta (of course), the mystery snails, neons (mine bred all the time-and in my tankit's caviar for breakfast when they do), so I'm stumped.

They look like nerite eggs. They won't hatch outside of saltwater.

Thank you. Glad they won't hatch in my tank. I'll clean them off next time I'm vaccuming the gravel. My water parameters and my feed must be doing okay-everything in there seems to want to breed!
