waat? 5 gallons per 7" fish? No offense dude but your "rule" is just wrong. you have to read this http://www.monsterfishkeepers.com/forums/showthread.php?88431-The-quot-one-inch-per-gallon-quot-rule you will understand a lot from this. Trust meIf you don't believe that then I will just post a picture of the fish that are in my tank . The main rule I follow is 5 gallons per fish . Less than 7 inches . Anything above 7 inches I let go in the same lake I caught them in .
