Had this problem trying to get glo-light tetras out of my tank. They were complete jerks and it took me 3 hours to get them out.
Here's a though though, try the bottle trap, but figure out a way to get it to float near the tetra's turf, like to it to some styrofoam or put a weight in the bottle, tie another weight to a string to get it to the right height and put the other weight on the outside of the tank.
You can keep trying until he falls for it, even if your other fish get trapped its not like its gonna hurt them or anything.
