About This Product

**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]**

Dwarf Tropical White Isopods (Trichorhina tomentosa) are the most popular species of isopods for poison dart frog vivaria and other bioactive setups. They're very small (under 1/4 inch), reproduce quickly, and are a great isopod to seed your vivarium.

Isopods make good 'tank janitors', helping to keep the environment clean while providing the occasional calcium-rich snack.

You will receive a 4 oz. container with 25+ Dwarf Tropical White Isopods, along with enough substrate and food to keep them going for a couple weeks. Each culture will seed up to a 29 gallon / 18x18 footprint tank. For larger enclosures, allow the clean-up-crew a month to grow in the enclosure before adding more, or purchase more cultures.

What do I do with this culture?

You can either add the isopods and the substrate in their shipping container directly to your vivarium by dumping them under the moss/leaf litter, or set them up in a larger container to make more isopods (check out our Isopod Culture Kit!). Fill a plastic shoe box about 3/4 full with Josh's Frogs Isopod Substrate, then moisten so that the substrate is wet to the touch, but water does not come out when it's squeezed. Add the contents of the 16oz Isopod Starter Culture, then feed and mist regularly.

Amazing Customer Service!

Reviewed on May 10, 2026.

I really appreciate how wonderful the customer service team is at Josh's Frogs. My initial order of these bugs were unfortunately DOA. After emailing support, they responded right away and after confirmation from me had a replacement order sent out the exact same day. When I received the replacement order, they were all doing great! I understand sometimes things can happen, especially when shipping live creatures, so I don't fault the store at all for the initial issue, but I was thrilled with how easily they were able to help make things right. I will definitely be continuing to order from here :)

They are so cute!

They arrived alive and well. I simply dumped the container into my tank and they happily disappeared into the dirt. They are so tiny and cute. Great addition to any bioactive enclosure.

Great Cleanup Crew!

These isopods are working great in my enclosure and established fairly quickly. I didn’t see them much while they were growing their numbers, but now that they’ve been in my terrarium for a few months they are very abundant and are breaking down any waste very well.

Awesome Iso's

Reviewed on June 13, 2024.

When these little guy's arrived at my doorstep I was thrilled to get them into my tank! When I opened the box to check on them everything was fine, and I could see them happily moving around! I put them straight into the terrarium, and I am happy to say they are settling in nicely! Will definitely buy a whole bunch more!
