Just leave it in for a week,
I mentioned tying a shrimp on a piece or rock or use elastic band but wrap it a bunch of times so they have to pick on the rock to get food. Kinda like you wrapping a bandage over a wound....and keep doing it even if they are inside don't get excited. Like training a cat to go pee in a litter box you can train your fish. Feed the fish only in the trap don't disperse food, eventually they will get use to the trap and then bam done like dinner!
