Calcium in Invertabrate Prey
In most invertabrate species, calcium is inadequate (less than 0.5 mg/kal). Those insects that do contain more calcium have calcified exoskeletons and will generally not be accepted for consumption. Whether commerical or wild-caught, invertabrate prey will require calcium supplementation. For calcium supplementation, try JurassiCal™ or JurassiCal™ Liquid.
