We have a 39 gallon tank that has a Dalmatian Molly (M), a baby Dalmatian/gold dust mix (F, 2 months old), a sunburst platy (F), a swordtail platy (M) & a Raphael Catfish (F, I think?). The platys seemed really chill and so we decided to get some more platys. We just got male & female Blue Mickey Mouse platys today and since we put them in the tank the swordtail has been chasing the female MM (& sometimes the male also) and totally ignoring the Sunburst female. (He previously mated with her but the only baby we found died) Is this because of the 2 F to 1 M ratio is out of balance? Because the swordtail didn't even chase the sunburst when she was the only female platy in the tank. I'm hoping he stops soon. Any thoughts?
