First of all I would like to say that the Vbulletin upgrade is nice.
This past summer I had a problem that I posted about a male platy chasing off one female platy and sticking close to the other female. It was suggested to me that the one I thought was a female was an immature male. I really didn't think this was true because I know how to tell the sex of a fish. Over the months I have added 4 more female platys to the tank and even later one male swordtail.
The male platy continued to chase off that one female (and still does), which never mysteriously turned into a male. The swordtail did attempt to fight with the male platy for a short period of time, and ended due to the platys body mass being too much.
The male platy never was interested in any female in the tank except for one that he stays close to and the other he tries killing.
Meanwhile the swordtail has become the pimp of the tank, but has nothing to do with the original three platys.
anyone else ever run into this?
