I did a quick search but every site said the same thing: "There is little or no sexual dimorphism between the sexes, but adult female flag tail characins are said to be plumper or more rounded than the males."
@@Fish-Story No problem, I was curious about my 12" flagtail as well. Other characins can be sexed by the concave shape of their anal fin, perhaps the same could be done by comparing a group of flagtails. Yours is much fatter than mine so I'd guess its a female and mine a male.
The smaller one's anal fin is hook-like, the back edge is concave. The bigger one's back edge is almost straight, pretty clear difference. Both fins don't look damaged so this is likely their genuine shape.
Beautiful Vic ,like the shape of that tank tbh m8

Appreciate the legwork. Thank you!

As we have two, I will pay attention to the shape of their anal fins.
