New pet isopod keepers consistently underestimate the importance of the substrate in their pets' tanks. A quality substrate is the single most important care factor in maintaining and growing your population of pet isopods. It is their primary food source. It is their shelter. It is their source for hydration. A good substrate provides all these things and any supplemental foods or products are just secondary.

Please review my Pet Isopod Care Sheet for more information and photos.

The most important ingredient in pet isopod substrate is small bits of decaying leaves from hardwood trees. These are best mixed into a mix of bases as described below where the densities and composition help to conserve moisture, and provide stability and structure for burrowing species.

Two options for purchase on this page:


1. The Composite Blend is ALL the necessary ingredients for captive isopods. Volume measures approximately 10 inches by 7 inches by 4.75 inches and consisits of soil, including composted materials, sand, sphagnum peat moss, calcium carbonate and two sandwich baggies of leaves. This is usually enough substrate to provide food for isopods cultures for maybe six months, depending on the size and number of individuals. It can be mixed in with your current substrate to freshen it up with all the healthy ingredients that may be depleted from it. $19.99. Free Shipping.

2. The Composite & Hardwood Cup substrate option is essentially the same as the composite subtrate above (w/two leaf bags) but includes a 3.75 ounce cup of properly decayed oak flakes. Sprinkle a third of the cup on the surface of the substrate every month or as needed. These fine bits are more easily chewed by isopods. They love it! $23. Free Shipping.

All organic material continues to decay through a natural process of decomposition via mold which you may or may not see. If mold forms as the substrate encounters all the native spores in the new environment (tank), it may be spot cleaned. The substrate may need to be turned over a bit. After a month or so the micro-ecosystem in your cage should come into balance. If you already have a seasoned cage set up, adding smaller amounts of our substrate to the tank over time will help to keep the current ecosystem in balance, while providing new food material for your pets.
