Hey everyone! As a new tortoise owner, I'm very wary of what I put in Sherman's (4 month baby Hermann) box. I use Cypress Mulch as substrate and currently have a rock hide, a log hide, a water plate, a few fake silk vines, a live aloe plant, and a live cactus plant. What are some other safe fake plant options or decoration options for him? Is sphagnum moss such as this okay?
