Cute little guy! I miss them... I would get the largest tank you can up and running. Maybe even a 55 gallon? Then you could keep more than one.
I'm guessing that one of the issues with a smaller tank is the amount of waste that cephalopods in general produce. The larger the tank, the more stable the water parameters are. Also, if something does go wrong (heater malfunctions, specific gravity is off, you put off a water change...) there is more of a buffer to keep everything stable.
