Livebearers changing genders

[cheeky_monkey]

I keep reading how someones platy, mollie or swordtail changed genders.

Can anyone point me in the direction of some actual researched factual evidence of this happening?

My understanding is that it's always females changing to males, which I would personally put down to late male development - not a sex change.

Can anyone give me factual info?

No-one?

I recently read an article about females changing to males, but I don't think there was any reproductive research behind it. They were just observations. Is there any place at all that we can find literature regarding aquarium fish? Actually, I'm sure there are papers out there regarding OTHER fish changing sex, maybe not platties specifically. I'm going to do a search on this tonight, since I have access to numerous databases.

Well I didn't find anything regarding platties gender-bending, but I did find articles that found female platties prefer males with sword extensions on their tails, even though platties are swordless!!!
There are a ton of articles about freshwater and saltwater species changing gender, but nothing specifically about platties, and I didn't see any about livebearers in general.

I only have experience when young livebearers develop enough to be males.
