Isopods are tiny crustaceans, often referred to as "pill bugs" or "roly-polies." Depending on species, they can range from 1/4 - 3/4 of an inch in length.
They make a great clean-up crew for bioactive habitats while also serving as a snack for small reptiles and amphibians.
For best results, add the entire contents of the cup to your bioactive substrate and feed weekly with Josh's Frogs Clean-Up Crew Cuisine.
Springtails (Folsomia candida) are tiny arthropods that are used as "tank janitors" in a terrarium, eating mold and waste. They also make a great supplemental snack for animals that like small food, such as dart frogs.
Springtails will reproduce in the tank. Simply add the entire springtail culture to your terrarium and mix it into your substrate. To keep springtail populations high, feed weekly with Josh's Frogs Spring to Life Springtail food or Clean-Up Crew CuisineTM.
