Exo Terra Feeding Rock

Hagen's Exo Terra Feeding Rock Reptile Cricket Feeder is an easy to use aid for feeding insects to your reptiles and amphibians. It reduces the amount of supplement needed as it retains excess powder that can be reused. The feeder prevents vitamin residue on the substrate, which may be dangerous as it can harbour harmful bacteria, especially in humid terrarium conditions. Ideal to "coat" crickets with vitamins.
