Babies take baby crickets or small roaches. If prey is too big, pre-kill it by crushing the head, leave it for the tarantula, then remove leftovers or bolus later. For super large specimens, an occasional pinky\/hopper mouse or feeder lizard can be offered very sparingly; excess calcium can cause constipation\/pooping issues.
