In rare cases, starving isopods may attempt to consume the carapace of freshly molted invertebrates or even gnaw on small or delicate reptiles or amphibians. We strongly recommend providing supplemental food to your clean up crew in the enclosure, such as Josh's Frogs CUC Cuisine. When in doubt, using dwarf species of isopods, such as Dwarf Tropical Whites, may be a safer option.
