the lfs where I got him tell me to bring in only males. they say they don't feel right basicly forcing people to buy 3 fish if all they want is the male, also they sell easier where as my other lfs will take in both male and females. then offer 2 different prices, male only is say $30 for example, but if u get male and 2 females, male is $20 and females are $10 each.
