One Molly never pregnant??

[sidgolding]

I have 4 Molly's 1 make 3 females and 2 of them are regularly baby machines but I have one White one that never seems to be pregnant. Not that I want them all giving out babies like there is no tomorrow but just wondering if there is a reason... She is pure white, could she be infertile?

Seems odd - is she the same age as rest? In good condition?

She is probably the happiest of them all. She is in great condition, no problems, eats well. All my fish are great but she just refuses to breed. If the male goes near her it's like he can't see her lol.

what are the colours on the rest? Maybe the males are colour blind

 

[sidgolding]

One female is orange and black, one is dalmation, and the male is all black with orange fins.

Fussy fish?!

I've had white-yellow platys that didn't want anything to do with some red platys. No idea why. There were 2 red males and about 4 white-yellow females so wasn't just one fish.
