He was sold to me as a male sailfin molly, but he also does not have a sailfin. Because he was constantly bullied by the other mollies, I isolated him and put him in a tank with two female platies. And... surprise, surprise, the platies have given birth twice now. And one of the fry I could recupperate on time is the male's exact spitting image.

So am starting to suspect that the male molly is actually, well, a swordtail!

What do you reckon? Photo 1 is him on his own, photo 2 is him with a sailfin molly male.
