I got my Axolotl from a lab research supplier. It was very cheap and he is very healthy. This probably isnt always the case but it felt good because he wasnt being sold to a research facility to have his gills cut off or a hectic classroom. Live plants are tricky, as they are being constantly uprooted, I would use the anchors they sell in the fish section. Whatever filter you choose, make sure it creates no current whatsoever. With mine I used the standard 10 gallon fishtank filter than sits on the edge of the tank and spills a small waterfall. Even this was too much, it obviously stressed him and he stayed away from that part of the tank. Just divert the water so it slows down. They are great pets!
