yeah, most don't, but like I said you can special order it. Just ask to talk to the aquatics specialist or the manager and say "I'd like to order this," if they can order it they will but in most cases you have to be available to pick it up the day and time that it arrives. They don't like to hold it for you.
(because then they put it into their system, then have to take it out and you put it in your system, plus it's already been traveling, it's just very stressful on the fish so usually they make you come get it when it arrives)
