Betta sex

[Tyler777]

Can a Etta expert tell me if my Koi Betta is a male or female ?

Thanks

I'd like to lean male, but if you can get a better picture where the side of the body is well lit, so I can look at the body cavity shape?

Males have a rounded shape body cavity while females have a long, pointed body cavity due to their ovaries.

Koi females can be just as vibrant and large as males, so it can be tricky with these colors.

I don't rely on presence of "egg spot" as I've had males have egg spots in the past, I don't find it as accurate as the ovaries vs no ovaries deal.

I will try to get a better pic tomorrow, they're sleeping now plus they don't actually pose for photos Lol

Look at the ovipositor (egg laying/ poop tube). Females have a white ovipositor, males have a coloured one.

Males develop a black beard (flap of skin around the lower edge of the gill covers), females don't have this.

Put a mirror next to the tank and see if the fish flares its fins out and tries to kill the reflection. If it does, then it's probably a male.

I have no opinion on gender, but whatever it is, a very pretty betta!!

It doesn't let me take good pics but I did my best
