I would upgrade my bedroom tank (a 2g) to a 20-30 gallon, buy a stand, a filter, and some more fish for it (probably a pim cat, pearl gouramis, and more zebra danios), and (if I have enough money left over), buy a giraffe catfish for my 220.
I would go get myself as close to wild caught frontosa as I could get, even go so far as to put out feelers trying to buy a breeding pair from someone. Then I would set up a tank and let them make babies and sell them.
From what I know of front's, they have always been a cash fish and will always be. Even more so if you can get wc moba.
