You can place the crickets in a small glass bowl and sink it into the substrate. The crickets can grip the glass so they can't escape. Easy pickings. You may also want to go out and buy some UNFLAVORED PEDIALYTE and prepare a bath at a 10 to 1 ratio. So for every 10 ounces of Luke warm Re-chlorinated water add 1 ounce of UNFLAVORED PEDIALYTE. Soak him for 20 minutes. This should provide a little boost for him. Also pick up some Fluker's Repta-Aid(Repta-Boost). You may need it as well.
