So I have a Sulcata tortoise right now in a 20 gallon tank. He is about 3" shell length now. He seems really bored and not very active in the tank. We have him in our bedroom due to we have no where in the living room to put him at the moment. I was wondering if I can get another tort to give him company? What would be the best tortoise to add that will eat the same stuff as him and not hibernate? Most importantly.....what tortoise can I add to the tank that won't get really big? I don't want to have two 200lb tort's running around due to no room for both and that would just be really unfair to them. One I can do but 2 would be overkill. Thanks.
