+1 using this method. I did the same when trying to catch some Zebra Danios. It also helps to bait the trap with food instead of stressing them out and chasing them around
. If you need it raised off the bottom or want to suspend it a bit, just tie some string to it and the other end around the lid.
As long as you are patient (since it can take a while) and place it about the same height they normaly swim, you'll get em. When catching more than one, I would just transfer them to a fry net as I got em one at a time. Just Google 2 liter fish trap and you will find tons of examples.
