Unknown eggs?

[ScotJudd]

I believe I may have some eggs in my tank. Pic below. They are about 0.5mm across, very tiny, and are hanging like a bunch of grapes. Does anyone know what they are?
Tank occupants-
Various Tetras
Bristle nose plec
Corydoras
Rams horn snails
Red cherry shrimp
Large shrimp, maybe amano
The eggs appeared this morning and will probably be gone by tomorrow but I am still curious about them.
Cheers, Steve.

Correction.
Snails are Malayan Trumpet Snails not Rams horn.

The fact that they are all stuck together in a clump kinda looks like a female shrimp just dropped all her eggs there. Although it's hard to judge size from that picture. From what I know about corys, they scatter their eggs over surfaces, BN plecos lay them in caves, and tetras are scatterers as well.

I agree.
Tetras found them this morning - the eggs are no more!
