I think the age is more around 2-3 years, sooner for males than females. If
you have 6" koi with roe, you probably got an older koi that was stunted at
some point in its life.... or it could just have short genes, oops, petite
genes. ;o) I have such a koi, I'm almost tempted to enter it in the young
koi section, even though I think it's about 5 years old or perhaps older.
I've had it 5 years. ~ jan

Have noticed some strange behavior this morning....there's definately
some chasing going on. 2 particular koi seem to be the ones being
chased. We got these fish last spring...at that time they were about
6 inches long and now they're 12 inches or better. I was under the
impression that they had to be 4 or 5 years old before they would
breed. Is this just adolescent play? Water temperature is about 65
degrees here on the Gulf and fish have been active for about a month
now.. Anyone know about this?
Pondering.....
