What do you use for a substrate for a 5 week old cherry head tortoise. Idk the real age I was told by tortoise town he was 3 1/2 months hached but when he arrived March 8th he was still healing from his egg sack he has a little pach of skin on the middle of his belly thay was healing still. I use coco coir only now after 2 weeks of moss and coco coir and I seen him eating the moss I think. And the coco coir gets all over his food already and Im sure he eats it I only hope sense it is so fine like ground coffee, but I know if it's not passing it will cause compaction so I try my best to keep his food clean I'll have to feed him outside of his tote and in one without substrate. I have a cypress mulch I havnt used.
