But he hated my other male so badly I had to retank him. He'd chase him all around the tank. This male he loves looks weird. Very very fat. If there's such a thing as a balloon platy, I may have bought one under another guise lol
Just don't use a breeder trap. Too much stress. More often then not they'll abort. Get floating plants. That said, the bottom of her belly will flatten, going from rounded to a straightened line, sort of, so she'll look like a box when she's close.
I have a red wag platy that will not leave my big calico (cant remember exact name) platy male alone. He tries to use his gonopodium on him all day long. I had another Micky male in the tank I had to move because red would dart at him, so I don't believe it's territorial. He likes the female...
