Could I have wrongly sexed my molly fish? Will young male molly fish look like females at first ? I thought I had 3 girls but Sasukes anal fun is starting to look different from the other two Molly’s even though it’s only been a month.
Sometimes if mollies or platies and guppies are kept with dominant males in petshops, they won't look like males until you bring them home.
This fishes analfin is becoming quite sharp, meaning it is likely turning into a male, though occasionally females do have a sharp analfin.
