Is My She A He?

[JellyPi3]

I posted yesterday about my platy i thought was dying. up until then i had belived it was a female. I had bought 2 male and 2 female red coral platie, and one male had died, so i was left with 2 female one male.
But by the looks of the fin, i am not so sure. It used to be fanned, but now it just looks pointed...i know how to sex a livebearer, but this one is confusing me. What is even more confusing is my other male is trying to mate it, so im not sure if it is a male or female. Do males try and mate.
The platy looks pregnant, but now im not sure...
Any help?

I'd say boy. you'll find that if you buy them young they aren't fully matured yet so occasionally turn into boys. They might be trying to dominate each other instead of mate? I get a couple more females before your one remaining one is harrassed to death by the two boys x

All immature platies look like females. The same is true of mollies, endlers guppies and swords. As they start to mature they start taking on the sex characteristics of their own gender rather than the generic look of the young ones. Since fish are often offered for sale before they have a chance to mature, it is not unusual to find there are more males in the mix than you knew about at the start.

Some male are suppressed when around other males, but doing this it allows then to grow larger and stronger than it's siblings as it's not thinking of mateing. This is all so referred as Late Developers.

This extra growth gives the suppressed male a better chance of mating when they finally mature, which has been known to take up to a year in some fish.
