Welcome to the forums and Texas... and good luck with the move. My wife and I just finished moving from one apartment to another in SA and fish tanks are definitely the hard part.

You might try calling the guys at a store here called Aquarium Designs. They are right off of 281 and it is an amazing store for saltwater. They have well-established tanks in their back rooms where they hold fish for customers sometimes. You might be able to (for a price) ship your fish to them and have them hold them until your system is set up.

I can't make any promises of course... it's their business. But it might be worth a try.
