I just got a female guppy to reproduce with my male guppy. My female guppy is about 2 inches and my male is twice it's size. My male guppy is only interested in the platies..
Criminintly, how did you ever get a male guppy that big I've got gorgeous mature breeding male guppies but none are four inches long! 2 inches maybe. I'm sure curious about him. What type is he? What colouring?
My mommas must be 3-4 inches easy. Maybe he'll realise he's got a sweet young thing when she matures abit? She sounds abit young yet by her size. Hope all goes well for you. I figure male guppies are interested in anything female! Hang in there and good luck.
