Sexing channa aurantimaculata

[Keibo]

Hi guys!
Any idea on the sexes of these two?
Guessing two males, but I'm not sure.


Sorry about the crappy quality, iPhone.

Hard to tell but they look to be males as they have lots of spotting below the lateral line. Females have larger orange markings and less darker spots below the lateral line. Might have to wait until they grow bigger.

Based on my own experience, the pattern on the body is not sufficient to distinguish between male and female.
However, the sexes can be quite clearly to distinguish the different color and height of the dorsal fin. So if you could provide pictures in which these two individuals were spreading out the dorsal fin, maybe I can help.

Males: high dorsal fin, with significantly larger blue
Female: lower back fin with a much smaller proportion of blue

The below article is a very good reference, while I cannot read German, I used Google to translate it into English.
