I'll be acquiring a 4' x 2' x 2.5' aquarium in the next month or so. I would love a Russian rat, but they don't seem to be readily available in my area. Black, yellow, and gray rats are illegal in Georgia, so I can't have them. Does anyone know where I could buy a Russian rat or any other species suggestions? Since the tank is so large, I'm looking for an active species with a reputation for a good disposition (we all know that individual temperaments vary) that is somewhat arboreal so they can enjoy the tank height as well. I am the only person in my home who is not afraid of snakes so it needs to be a species I can handle by myself, which is why I am avoiding larger constrictors. Safety is a must.
