I actually have a slate rock slab I could use! My beardie uses one for his basking spot lol. They work amazingly well to retain heat without burning their tummies. He took 6 big mouthfuls of food before I placed him back into his enclosure. He was offered a mix of yellow bell pepper, prickly pear fruit, cilantro, parsley and sweet potato. He's very curious of everything outside the enclosure, and enjoys investigating! He has become a lot more active being on his own, without another male dominating him. On a side note their clockwork is all messed up... Now being supplied with real temperatures, they believe it is breeding season!!
