Well I didn't plan on having unexpected fry 2 months ago, but I now have a total of 9 guppies that I've separated males and females. I have one very tiny super small guppy in my male tank that I cannot tell yet whether he is male or female yet, he doesnt seem to be growing. So unless he's a male, I don't see what the males are fightin over, you totally cannot tell what sex he is yet, even though he's the sibling of the other 4.
