i know its pushing it but im asking any way. can a SB sen live its whole life (or atleast the first 3 years) in a 20 long and be ok? the tank is 30"L x 12"W in case you didnt know. and i ask because the primer says the minimum tank size for senegals is a 30 gallon, which has the dimensions of 36"L x 12"W, its only 6" longer than my tank. is that such a big deal?
