I have seen it done before without any problems. That does not mean,however, that I would recommend it. The only thing that would concern me is the snapper potentially biting off the foot, toes, or tail of the gator. This sort of thing can happen while the snapper is "fishing." Another thing is that both those animals generate A LOT of waste. You will have to do frequent water changes with two potentially dangerous animals. Also American Alligators grow really quickly in their first couple years, far faster than the Alligator Snapper will. That means they may not be able to live together for very long. An alligator will grow to 2' in its first year, it can be 3'-4' at age two or three. Thats big enough to do considerable damage to anything, including a snapper head, tail, or leg.
