Mine are very willing hand feeders, but I can't say it's ever something i set out to do. If your FBT can't be free fed, and is being stressed by the tongs, then I would suggest gently getting the toad into a tub with some crickets in, cover it up with a cloth or something so it is dark and leave the FBT to it for a good while. If you have a large tank there is no reason you can't leave it sitting in there. I found this was one of the only ways one of mine would eat when I first got it.
