Everything I've had experience in says all of those fish require a 180 gallon 6'x2'x2' tank. Festae and Argentea especially.
I've never bred odoe, but I've kept multiple fish in a smaller 100 gallon tank and had aggression problems.
I think your best bet is the pike - a mature male festae will most assuredly kill his mate in a tank that small. You'd be able to get away with the argentea if you found a bonded pair, and the pair kept that bond during the tank transfer.
