It took me a while to figure out how I wanted to set up my russian tortoise's enclosure, but I think I'm finally on the right track! First of all, I had to change his substrate because he was NOT a fan of top soil. He didn't dig in it, he wasn't as active, and he constantly had dirt stuck to him. I changed it to a mix of loose and soft coconut fiber since I couldn't find coco coir and he loves it!! He is always roaming around, digging, and just seems happier now. I also have his lights situated in good spots finally ( I do use the clamp lights, but I have something holding the cords in case the clamp fails) and I feel like he has a lot of room to explore. He also likes going through his tunnel it's so cute to watch him roam around I swear I could sit for hours on end watching him. I do want to add live plants to his enclosure and more things for him to climb on, but for now I think he likes it!
