I raised Fronts and O's in 300 gal. stock tanks over the summer (when I was a bachloer) I wish I still had them, but I don't think wifey would like them on the patio. I used them for Fronts and O's. The O's def. grew faster than the Fronts. I think next time I would do Large Haps. and faster growing Peacocks. I would also set the tanks out earlier like end of April/early May and heat them. Summers in IL and Iowa are short and it would extend the growing season. Like stated earlier, the colors the fish get from natural sun plus plenty of room and food makes colors awesome.
