the picture isn't big, or clear enough to clearly to the anal fin to determine the gender of the fish, so we dont know whether or not its a male or female.
just a reminder everyone
we cant determine the sex of the guppy by color, the male guppy I posted had some females in the tank with much more color than he did, so just because half of the body is black or a solid, bright color doesnt mean it is necessarily a a male guppy
