About This Product

Josh's Frogs Tropical BioBedding Bioactive Substrate (4 quarts) is the perfect substrate for your tropical bioactive enclosure. Tropical Biobedding is a unique blend of organic and inorganic ingredients, trace elements, and beneficial fungi that serves to jump start the bioactive environment. Tropical Biobedding helps maintain humidity while providing a substrate your pets can dig and lay eggs in, all while helping to maintain healthy populations of microfauna.

  • Tank stays cleaner due to bioactive cycle
  • Less substrate changes, which is less stressful on your pet
  • Closer to replicating your pet’s natural habitat
  • More attractive than traditional substrates

How to Prep: Mix contents of bag thoroughly. Place a 2.5-3 inch layer of Tropical BioBedding in your enclosure. Add dechlorinated or R/O water until BioBedding sticks together when squeezed, but no water runs out.

Recommended Animals: We do not recommend using Tropical BioBedding with Dart Frogs or anything that requires high humidity and low ventilation.

  • Crested Geckos
  • Mourning Geckos
  • Indopacific Tree Geckos
  • Bauer’s Chameleon Geckos
  • Day Geckos
  • Gargoyle Geckos
  • Leachie Geckos
  • Tree Frogs
  • Bumblebee Toads
  • Yellow Spotted Climbing Toads
  • Mantellas
  • Malaysian Horned Frogs
  • Water Dragons
  • Anoles and other tropical lizards
  • Tegus
  • Tropical snakes
  • Plus many other reptiles, amphibians, and invertebrates

Recommended Plants: Terrestrial plants can be planted directly into BioBedding. Tropical BioBedding is a great substrate for most tropical plants, but make sure to match your plants’ needs to your pets’ environment! 

  • Tropical Plant Kits for Animals

Suitable for Misted Setups: Yes. Tropical BioBedding does not require a drainage layer if used with light or hand misting. For automatic misting setups, use in conjunction with a 2 inch layer of Josh's Frogs False Bottom and a Substrate Barrier. Use our Substrate Calculator now (but replace ABG Mix with BioBedding). 

Care: Tropical BioBedding is a naturalistic vivarium substrate and is meant to house a bioactive clean up crew! Stir the surface of Tropical BioBedding every 1-2 weeks with a fork, or if waste is visible. Burying waste allows microfauna to process it quicker. Change the substrate when it begins to break down - typically after several years. Please note that Tropical BioBedding is designed to grow fungi - this is not a sign of a dirty tank, but of a healthy, clean bioactive environment.

Not sure if this is the right substrate for your pet? Josh's Frogs also offers Coco Select, Dig It, ABG Mix, Coco Cradle, incubation media, feeder insect beddings, various shredded barks like Aspen, Cypress, Pine, and more!

Amazing substrate

This substrate is amazing. It's the only substrate you'll ever need. I have no idea what's in it but it feels and smells amazing. My vivarium is thriving with it.

Looked and felt great!

Unfortunately my dog got into my substrate and spread it across the lawn before I had a chance to use it in an enclosure, but just looking at it before I could already tell it was amazing quality, with properly balanced ingredients. I'm really disappointed that I didn't get to use this substrate, but I'll definitely be ordering more! (And this time I'll keep it out of my dog's reach)

Does the job well done!

After a few months of settling in, using BioBedding for my day geckos has done wonders! The isopods and springtails both do well, and plants do well on it as well.
