Hope you don't mind me adding this pic of one of my own bred female mini's. Forget the base colour as this is variable with most rays, its the first 3 rings that cover the rays first 2" of the outer disc, perfect small round spots. I must point out that because of slight variations in patterns this trait is not so evident with every single mini but in the majority it is.
Your male will be able to mate his bigger female when the time is right.
All the best.
