has this ever happened to anyone? once, my mickey-mouse platy gave birth to a two-headed fry! it swam really oddly and it got stuck in some gravel and apparently died. it would have been cool to see what it looks like as an adult.
A deformed platy. I've seen it before. Even if it hadn't got caught in the gravel, it would've probably died before adulthood anyway. Deformed fish usually don't live very long.
