I have two mature female platies in my wee tenner at the moment along with a male and immature female. They seem to be working on drastically different gestation rates.

My big neon orange mickey delivers just about every 4.5 weeks. My smaller all-red seems much slower at about 7 weeks between broods.

Could it be that the red is not fully mature yet? She is about 15% smaller than the neon. Is she possibly ill? She seems normal and all the other fish as well, water tests fine. Or does it just sometimes vary that much from female to female?

I'd think it's more about genetics than age. Older females tend to have larger broods, but not faster. Line bred varieties can have differences besides looks and one variety may have longer gestation.

Your tanks aren't too small. Your fish are too big.

The big neon momma just delivered another brood just 26 days after the last. This girl is quite the babymaker.

It has been 40 days since the red mom delivered and she is barely looking fat yet.
