The Pacman food is a balanced diet for them and we have never had a frog refuse it. Variety is the key for the Pyxies. They will eat until they explode, so it's up to you to limit their diets. We feed mainly earthworms & a similar food to the Pacman food (our own formulation) and they are healthy & do well on this diet. Pacman Food may not be economically sound with 8 adult Pyxie Frogs. We have 2 juveniles and they are garbage disposals!!
