well i have an undersized tank for my whites because i dont have that much money. but it really should be a 50 or 60 gallon(sadly mine is only a 30, barley enough for 2) but with how mine are doing 40 should be fine. just becarfull of poop buildup. its very hard to control so clean the tank out entirely once a moth. alot of work but u gotta do it. ( think about it, i have 5 tanks to clean out every month). if u can, buy medium sized ones, so u can get a bigger tank as they grow. dont buy babys, its easy for them to get diseases. mine are about medium size but they're still growin'...fast.
