Greetings! I have quite a predicament, and I figure at least one person can help me. See, I have a couple of savannah monitors: Lili Ann and Pax. They are both still quite little, but well...they will get larger very soon. My dilemma is that I have them in a 75-gallon tank. I will not be able to get a 400-gallon tank, let me say, and that is what a full-grown savannah monitor needs. Is it alright if I walk them around the neighborhood and park (grass and dirt, no cement) every single day for an hour or more (each at different times) and keep them in, say, a 120-gallon tank? Let me know. Thanks so much! If you are worried about their situation, don't worry. If this proposal won't work, I will then simply try to get a larger tank, or let them walk around a room designated for them or something along the lines of that.
