Mesh for separating danios from eggs?

[gau]

Could anyone guide me to buying plastic mesh? I want to breed my LF zebra danios and am looking for plastic mesh.

I found a size 7 on ebay, but it might have too small holes for the eggs to fall through.

Would this mesh be small enough for the eggs to fall through? Plastic mesh

How about this?

Could anyone suggest cheaper alternatives at stores, instead of online? Marbles just are too costly to ship. Anyplace with cheap marbles?

Any craft store will have those 12"x12" sheets for like 59 cents. AC Moore, Michael's, and Joann's Fabrics definitely do.

Look in the dollar store for marbles.
