Leaf litter for vivariums: what it does, which leaves, how much
Written November 2026 by Lone Star Leaf Litter, the family business that keeps this archive online.
We sell Texas live oak leaf litter, so weigh our preferences with that in mind. Everything below is general practice you can check against the forum threads linked at the end.
What leaf litter does
Leaf litter is a loose layer of dried, fallen leaves laid over the substrate. In a planted vivarium it does several jobs at once:
- Cover. Small frogs, geckos and invertebrates hide and hunt under it, and many dart frog keepers find their frogs bolder when cover is close.
- Food and housing for the cleanup crew. Springtails and isopods live in the layer and eat the leaves as they soften, along with waste and mold.
- A drier surface over damp soil. Animals sit on leaves instead of on wet substrate, while the soil underneath stays moist.
- A slow source of organic matter. As the leaves break down they feed the substrate and the plants rooted in it.
Which leaves keepers use
The leaves that turn up most in the hobby are live oak, magnolia, sea grape and Indian almond. They differ mainly in size and in how fast they break down.
- Live oak leaves are small and leathery. They suit small tanks and small animals, and they hold their shape for a long time in humid conditions.
- Magnolia and sea grape leaves are large and stiff. They make good hides in bigger enclosures and also last well.
- Indian almond leaves are thinner and soften sooner, which is why they are popular as isopod food and in aquariums.
Many keepers mix a long-lasting leaf with a softer one, so the cleanup crew has something to eat now and cover that stays put. We compare the options in more detail in live oak versus other leaves, and cover the isopod side in choosing leaf litter for isopods.
Collecting your own
You can collect leaves yourself if you know the tree and the ground it stands on. Take dry, brown leaves that have already fallen. Avoid lawns, roadsides and anywhere that may have been sprayed with pesticide, herbicide or fertilizer. If you cannot identify the tree, leave it.
Preparing it
Keepers disagree on this, and the old threads here show it. Some boil or bake collected leaves to cut down on hitchhikers. Others add them dry and untreated, on the view that a working cleanup crew deals with what comes in. Heat reduces the risk but does not guarantee a sterile leaf, and it softens the leaf so it breaks down sooner.
Our own leaves are hand-collected, sorted and screened. Screening is not sterilization, so inspect any bag, ours included, and follow the husbandry advice for your species.
How much to add
For dart frogs, a layer about one to two inches deep across most of the floor is a common starting point. Leave some open ground near feeding spots and water.
For volume, multiply the floor area by the depth. A 12 by 18 inch patch at one inch deep is about 216 cubic inches, which is just under one US gallon. Leaves settle and overlap, so treat that as a starting figure. There is a fuller walk-through in our setup guide.
Keeping it going
Leaf litter is consumed. Top it up when you see bare patches or thin cover. How long a layer lasts depends on moisture, temperature and how many isopods and springtails are working on it. Some mold on new leaves is normal in a humid tank; heavy growth usually points to too much moisture, too little air movement or uneaten food.
