I wasn't sure if this section was the right one. I have a swordtail I guess, I mentioned "I guess" because it was sold to me as a platy. She is acting strange since today, I had her in a different tank with some platy and since today the other fish started to bully her(in the past she was the bully) She looks plumpy but I can't see the gravid spot or at least I think it not.
