Funky green eggs?

[Lonelypeach]

Just moved my male Betta to a new 5 gallon planted tank recently. He's having a bit of stress issues but we're working on that.
He lives with 4 cherry shrimp and a zebra nerite.
Today I found a little bundle green spheres attached to the java moss. Can anyone tell me what these are? Eggs? Poop??? WHO DID THIS

Interesting, they could be Nerite eggs, usually look like a sesame seed and in a spaced out line or randomly, though these are apparently clumped! Hmmm. No other snails in there???

They wouldn't be poop or from the cherry shrimp.
