How to tell Kois gender? Can't Post
Hi everyone.

Since I'm new and about to purchase my first bunch of kois( don't know when, have to gain knowledge first), I would like to know HOW to differentiate the Kois males and females. I was thinking of buying in pairs consist of equally males and females and not just rather scoop up the most beautiful Kois from the tank and into the plastic bag.

Please help anyone, any gurus, any professors, experts, angels....

Hi zaini, Unless you plan on buying large koi you wont be able to sex koi under at least two years of age. When spawning two males to every female is what you need to do. So it is better to have more males than females and of course if you plan of spawning is is best to spawn Kohaku to Kohaku and so forth. When looking for a male their wil be a sandpaper fell to the gill covers on a male , so you will have to touch the koi before purchaseing to make sure of the sex, also males pectoral fins are longer and females are more rounded. The best way to tell if you have a female is in the spring she will swell with eggs. FAT BELLIED and males are longer and more streamline than females. I suggest that you buy from a good dealer like Keirin Koi and get you what you want. If you buy small koi you just have to wait and see what you have. Even the best Koi dealer can't sex the koi when they are young.
Good luck
Judy

i have to disagree slightly with koifishgirl, you can sex usually at about 8-10 inches (i find) basically males look a lot more streamlined thinner bullet chaped body where as females are generally fatter, also if you feel a kois gill plates the males feel like rough like sand paper as females are completely smooth!

Once you start koi you just can't stop.

Thanks guys for the references and tips, it sure help me for a start.

Don't know whether the owner of the aquarium shop would let me touch(raba-raba) his Kois. He'll probably strangle me to death...

But thanks anyway.
