Is my Platy fish pregnant?

[SolarSystem]

Hello, I got this Platy yesterday, does she look pregnant?
She has also developed some odd behavior hiding, going in the corner of the tank on the top and “convulsing” what I mean by this is her tail goes down(curls it almost), so does her top fin and her analfin stretches out.. She has also been hiding in plants and being skiddish.
She ate today but earlier went on a fast where she was refusing food.
Is she about to give birth??
Thank you for any info, also everything is perfect with the tank.

hello solar system, not every day you meet an entire celestial body on an internet forum!

I’m a bit rusty with livebearer gestational stuff but it’s usually safe to assume any female you have is pregnant, particularly with recent exposure to male counterparts. Includes swordtails and a few others in the case of platys. you might be able to see a gravid spot (small black-coloured spot under the skin near the anus) but with your girl’s colouration it could be hard to see. Knowing platys this one could have a while to go, look out for a more angular shape to the belly and potential some little eyes in the gravid spot.

one way or another, you’ll probably have some babies within a few weeks, congrats!

She could be pregnant or just well fed. Not really clear to see from these angles. Also a non pregnant female will show a gravid spot. The gravid spot itself is a translucent part of the skin or a piece of skin with a low density of chromatophores (color cells). With a high density of color cells at that spot, you wont be able to see a gravid spot. If a female does get pregnant, the skin stretches more and more during pregnancy. This means that the skin overthere becomes thinner and the more thinner it gets the better you'll be able to see the embryos shining through that part of the skin (what we call the gravid spot). So, the gravid spot itself is not a sign of pregnancy if you read this reply well.
