Hi all, I was looking at my female swordtail in my tank tonight. Does she look pregnant to you? She was not that large when I first got her. She’s a marigold swordtail. Mind the flakes, I just fed them
Probably. If so, she'll get bigger and develop a dark gravid spot. Livebearer females are able to store sperm and use it to self-impregnate like 3-4 times. So even if there are no males currently present, she could be "packing" from her contact with them at the fish store.
There is a male sword of the same species in the tank with her. The two get along just fine, swim together peacefully
More than 10 years
She is likely pregnant if she has been with the male for more than afew days.
