I used coconut fiber substrate for my baby Hermann’s Tortoise but it seems super fine and it looks like it may get in his eyes! I sprayed the substrate with water to increase the humidity and it seems sticky and makes the baby all dirty. It’s only on one side of the enclosure, the other half is more course coconut bark. Is the coconut fiber substrate really safe even though it seems too fine? If he burrows in the substrate, how is he going to breath? I may be just worrying too much... Thank you in advance for everybody’s advice.
