The right reptile substrate depends on humidity, not looks, which is why a substrate that can be used bone dry for one species and misted for another is worth more than one built for a single climate.

Pettex's Reptile Cocofibre is 100% natural coconut husk fibre. Kept dry it's odourless and suits an arid, desert-style terrarium; sprayed with water it holds moisture and becomes a tropical dwelling substrate instead. The same material also works as an incubation medium for reptile eggs and as a natural planting substrate.

What the label does not say. Pettex don't publish how often to replace it or which species it's unsuitable for, so that judgement call is down to researching your particular animal's needs rather than anything supplied here.

Who it's for: keepers of tropical or desert reptile species who want one substrate they can use dry or misted, and that doubles as an egg incubation medium.
