What foods are best for trapping snails and Neocaridina shrimp?

[MattW]

I need to remove some ramshorns and neocardina shrimp soon, and in the past, I used a net and long tweezers (for the snails), which worked but was a pain and took over an hour. My tank has dense plant growth, so the second the shrimp see the net, they flee.. I thought I'd try leaving a larger net with some food inside this time. Any suggestions?

I saw a utube where a cabbage leaf was floated on the surface of the water overnight. The next morning tons of snails had attached to the underside of the leaf. Then the leaf was removed.
