harvesting

I am looking for tip on how to harvest bribe shimp. Also does anyone have a specific net suggestion or alternative? The two nets I gambled on were not fine enough.

Hey so instead of the regular toothpick or paintbrush methods anyone try laying a damp coffee filter on top of the culture and leaving it there then using a spoon to scrape off the micro worms from the filter without getting any of the cornmeal, baby food, oatmeal or whatever grow media used...
