Even so, male and female clowns will not always pair up, so the answer to your first question is: maybe.
i dont think the first has to be bigger, i got 2 false perc's about 1 1/2 years ago they were both the same size, and one recently changed into female and the other male before, (tear) :...(, my female tragically dissappeared, but i did buy em at same size
