Hi, I bought a new platy just over a week ago, she was kept in a tank with other males at the lfs, i'd seen her at the lfs a week or so before buying her too so she must of been there for a few weeks with other males. since ive had her my male has been chasing her etc. and i have actually witnessed them mating. so she must be pregnant, but i thought she was only a week or so pregnant, upon looking at her she's rather round and also squared off, i hadnt noticed this before. but i cant find a black gravid spot, although there is a light red/pink spot where the gravid should be or is it just part of her insides? her anal canal is also open as i can see a white spot. i have put her in a breeding trap just incase. is she about to give birth or is she just overfed? any help would be greatly appreciated!! thank you
