I bought my Female Platy fish a 23 days ago along with two other female Platties. I noticed extra black spots have grown also a slightly dark spot at the bottom of the fish. Is it likely that she is pregnant??
She doesn't look pregnant, but it's always a possibility with female livebearers. Even though it's been 23 days since she was last exposed to males, they can store sperm for six months and become pregnant any time in that period by using what's stored.
