I have two red-foot tortoises. I got them as hatchlings from a reputable breeder who has been very helpful with this very novice tort owner. I have a question about substrate. Currently, they are in a 40-gallon breeder tank, and there is coconut fiber as substrate from ZooMed - recommended by the breeder. I would like to switch over to cypress instead because it doesn't seem as "powdery." My little ones are about 3" long now, and they really burrow in the bedding. Will they be able to burrow like that in the cypress? They have a heat lamp on one side, UVB on the other (the "cool" side), a hide and some plants that also provide a "hide" area. They love those plants (artificial). I just got them a little "pond" which they ignore. The basking side is kept at between 90 and 100 degrees, and the "cool" side is between 80 and 90 degrees. I recently added a fogger which ensures humidity in the proper range (according to the temp/humidity monitor). They are eating Mazuri, peppers, flowers, Romaine and several other greens along with meal worms and grapes which they love. They have almost doubled in size in the past few months. So, will they be okay with the cypress over the coconut? I should also mention that they get a 20-minute soak in the kitchen sink every evening, and in the photo, they are eating their after-soak dinner on a dish cloth on the kitchen counter. LOL I love to watch them eat. They are always supervised until they are in their tank. Thanks, Karen
