The advise I give to anyone wishing to own an exotic pet is to make sure you know where your pet is coming from! It is illegal to ship most animals in from other countries (like Central America), but this type of poaching happens all the time. I think it is a lot easier to get an Axolotl bred in the US than most exotic animals, but double check all the same and know that you are getting your pet from a breeder in the USA.
I see that you live in Florida, and I know that there are a LOT more illegally imported animals in FL than other states due to its proximity to Central America. So like I said -- don't be afraid to ask questions and find out who the animal came from (or, even better, go directly to a breeder and cut out the middle man, a.k.a. the pet store).
