Im not sure. She is bigger than my other platies.


I'd say she's not heavily pregnant (though being a female platy she's probably at some stage) - when she's further along, you normally see a darker area towards the back end of the belly; sometimes you can even see dark spots which I'm told are the babies' eyes. If you look at the first photo (just above the so-attractive string of poo that platys love to trail around with them), that area will be darker and fatter.
Platys do seem to have their own personalities, and some are more active than others - is she showing any other signs of illness? Not swimming around much could be a sign of stress? Are there other females there (couldn't really tell from the pics) - is it possible she's getting harrassed by male platys?
Is it possible she's just older than the other platys and they're still growing?
Females are normally bigger than the males.
Thats overfeeding i guess so. It has swim bladder also. Watch out on your feeding. Feed less more fish will survive.
