I have a little orange platy girl (I believe it's a dwarf coral platy)... It's the only one that survived out of five because my bichir decided to eat them.
However, I've been slowly noticing it getting bigger and bigger, and at first this maybe the reason why the bichir didn't eat it because it was eating well and growing the fastest out of the other fishes. It is also functioning just fine: no swiming issue, no noticably lethargic action, eats well, poops well (poops really well, maybe too well). Yet, from all the articles I've read online, my fish shows no gravid spot. When I stare at it's rear belly near its poophole, I see some clear spherical things, but it's not clear.. it could be organs for all I know. I also don't feel as if he has raised scales. I've looked at it up close and looked at it from above, no real "pine cone" look. Then again it's belly seems really stretched!! I've also seen people mention the fish looking boxy from the back view, and I definately think it looks boxy from the side more so than the back. It's been few weeks now that my platy has been big... Another thing too is that I cannot determine if his eyes are popping out. If I could take a picture I would, but my camera cannot focus on something this small.
