Hi koko great! I was wondering how to sex them. How do you determine sex in koi? Do you know? I have both. Also I LOVE your woman and koi pix! Can you tell me where you got it from? Thanks, pondgirl. My email is : alison19782004@yahoo.com

Out of all the fish that I have had, I thought that I knew for sure that my gold lionhead was a male. It always acted to "tough". Then one day eggs started falling out of her. I am going to use that picture from now on to figure it out!! Thank you koko!!

Neato koko. I thought that you could only determine the sex when they were getting ready to mate. But it's good to know that you can whenever. I'm guessing as long as it's over the age of three ??

Another way to tell males apart is by looking at the front edge

of their pectoral fins and their gill plate covers. A mature male

will have little white bumps or dots (not to be confused with ick),

and the fin will be thicker on a male, while the female's will be

thin. Another thought is the male pectoral fins will be pointy,

while the female's pectoral fins will have a rounded shape.

Normally, fish become of age around 2 years old. Some

show signs earlier than others though.

Great pictures, but I still can not tell. I can not visualize any hole on the underside of my fantailed. Perhaps it is a female and located lower between the fins and that is why I can not see it. There is an awful lot of tail in the way. I do not see any white spots on the gills.

Could breeding tubercles be present/visible on the first spine of the dorsal fin?

I am havinf trouble with all the other indicators of genser - GN lives alone in his tank - so by no thaving females around, maybe he doesn't really go through the "spawning" thing? Like, it would be a reaction to female hormones in the water - but there are none, so how can I tell if my fish is a boy or a girl?

I want to figure it out for certaina s I am thinking of getting another fish and I don't want any fry! Thanks!

Mine were easy to name, Valentine and Cupid, so they can keep thier names whether female or male, lol

Valentine has a heart shaped black spot on its head, so Cupid was easy to name after that, and add in my albino Placo named Red it all fits, hehe :heart
