Call them to see what they have; take what they have listed on AquaBid with a grain of salt.
I was going to get a jardini arowana from them after seeing one of their auctions on AquaBid, and I called in regards to getting a shipping quote on said jardini. The response I got was, "Oh, we are out of that size; we only have X size for Y dollars," to which I responded with, "Oh, okay. Then why is there still a listing on AquaBid for the size that you're out of?" and didn't get a straight forward answer.
It might have been a fluke incident, but I would call just to be sure they have what their AquaBid listings say they have before placing a bid/Buy It Now in order to avoid any unnecessary hassle.
