About This Product

LIVE ARRIVAL GUARANTEED if your temps fall within our LAG (read here). Please check your temps before ordering!

**If Isopods experience a rough transit and do not survive their trip to you, the container will often appear empty or shorted as they disintegrate and disappear. If this happens, please contact [email protected]**

You will receive an 8 oz container with 25+ Dwarf Tropical White Isopods and an 8 oz container containing temperate springtails. We've found that these two species are the best for most bioactive enclosures.

Dwarf Tropical White Isopods (Trichorhina tomentosa) are the most popular species of isopods for poison dart frog vivaria and other bioactive setups. They reproduce quickly, and are a great isopod to seed your vivarium with. We also recommend using the starter culture to start a larger culture. 

Springtails (Folsomia candida) are tiny arthropods (1-4 mm) and are used as "Tank Janitors" in a terrarium, eating mold and waste. They also make a great supplemental food for your poison dart frogs. This 8oz culture houses springtails on a dirt like substrate, which can added directly to your vivarium!

When you add springtails and isopods to your tanks they will reproduce. Simply dump the entire culture in your terrarium and mix the substrate in the springtail culture right into your substrate.

Feed weekly with Josh's Frogs Spring to Life Springtail Food

If you are not adding to terrariums, we recommend that you buy a starter culture and use it start a larger culture (we use 5 qt. Sterilite containers). Larger cultures produce better and are less prone to CO2 buildup. If you use this smaller culture to start a larger culture to feed froglets or seed multiple tanks, allow the culture to grow for a month before use. Each culture will seed up to a 29g / 18x18 size tank. For larger enclosures, allow the clean up crew a month to grow in the enclosure before adding more, or purchase more cultures.

I did my first ever bioactive terrarium and bought these and so far they are doing really well! At first I was a little worried as I couldn’t find any of the isopods for a couple days but eventually I saw some and they were just a lot smaller than I expected and must of missed them at first. After this experience I’m definitely going to keep doing bioactive!
