I got my T about 5 months ago I enjoy her very much, I had a cage set up by the pet store 20gallon glass with screen on top.Recently I just changed the substrate with coco fiber I put a hole in the soil but she wont burrow.What is the best to use?I heard of peat moss and vermiculite blend I dont know what that is or where to get it? I looked and looked can someone tell me the brand name of each they used with picture would really help Thanks.
