I'm a bit obsessed with fish
I've looked everywhere for answers but I can't seem to find them.
I have a female swordtail fish who I believe is pregnant. She has a dark gravid spot by her bottom and has gotten larger a couple times (I think she might have eaten her babies).
She can swim just fine, but has been acting weird lately. She eats a little but not as much as she used to and sometimes she just sits in the middle of the tank with her fins pinned down looking very unhappy. I've been watching her for a while and she looks healthy to me. Her fins aren't torn and she doesn't seem to have any spots on her.
Is she acting weird because she's pregnant or is she sick?
