Can you use stagnant moss for green tree frog substrate?

Yes, stagnant moss can be used as a substrate for green tree frogs, but it's important to ensure that it is clean and free of mold or harmful bacteria. Moss provides good moisture retention, which is beneficial for these amphibians, as they thrive in humid environments. However, it should be supplemented with other materials to create a suitable habitat, such as leaf litter or a drainage layer, to prevent waterlogging. Always monitor the substrate's condition to maintain a healthy environment for your frogs.
