Where in AZ are you living? There are a few places in AZ that are nice. I just went to Aquatouch(.com) in Phoenix, Awesome Awesome store. also Petsinc(.com) in Tempe, though I've never been there and mail order would be AZ gardens(.com) in Oro Valley by Tucson. Those are way better than chain stores. they will only have the same 4 plants here in AZ from what I've found. I miss CA where they would have their own gardens of a dozen or so terrarium and immersible water plants.
