ok so i've currently got 2 true percs in my 14g biocube, but im trying to sell them so i can get 2 black and white clowns(if you want 2 true percs and live in toronto, pm me). are there any special requirements for b&w clowns? i heard that black and white clowns are usually big becuase in order for them to be fully black they must be adults. i really like the clowns that are completely black and have no orange, what would be a decent price for a pair?
