Winegrowers Supplies  -  Stainless Steel 'Rectangular' fixed capacity Tanks for fermentation and storage

If these tanks are not full then, to stop oxidation, you need to put a 'blanket layer' of CO2 gas over the contents; CO2 is heavier than air. It's not expensive to hire a CO2 cylinder, contact your local pub to ask where they get theirs from.

Rectangular tanks are considerably more expensive than normal cylindrical tanks, but if you have limited space in your cellar then they can be the best choice.
There are two options, stacking or compound; compound being a single tank with intermediate partitioning.
