    Around a month ago we had 24 guppy fry.

    Ive gone to sex them this evening and 1 is about 3/4 of the size of all the others. This is the only one with a tube like fin, all the others had definite triangle shaped anal fins.

    Is it normal for male to be smaller?
    and is it possible to have 24 fry and only 1 be a male or is it too early to tell?

    Thanks

    It's quite normal for males to be smaller than females, as for a batch of almost all the same sex I've heard of that too & batches of all the same sex
    Some people think it could be to do with temperature though no studies that I know of have been done to prove the theory

    Ive just found another male, its the largest of the fry and first to develop red in its tale. It has a black spot appearing on its side so I dont know if theyre endler guppy crosses. The mother guppy was pregnant when we got it so the next few weeks should be interesting
