I use the non-pointy end of a bamboo skewer to do this too. They will follow it to the surface and I nudge the pellets around and they will snatch them fast and retreat to the substrate as if they were hunting for terrestrial insects or insects that dwell on the surface of the water in the wild.

Their "eat and retreat" method of hunting can be rather amusing to observe.
