    How to predict if a koi will grow a shoulder hump or not?

    I personally dislike koi fish with shoulder humps, and I would want to be able to know whether or not a certain fish will grow a shoulder hump or not. In the future when I choose koi fish, then I would know. There certainly are ways to tell how they will look like when matured, and it has something to do with the shape of its head and gill plate?

    Is it if they have a narrow head they are more likely to get the hump rather than those with big wide heads. Something to do with wife head allow for the fish to grow outwards as well as length whereas a narrow head means the shoulders are more restricted. I can’t quite remember where I hear this or if it’s true though. I may well have dreamt this up How to predict if a koi will grow a shoulder hump or not?

    Makes sense, however don't practically all juvenile fish have narrow heads? Then some heads widen while some stay narrow. For you, are humps a good thing?

    The differences are very subtle in tosai but become more obvious as they get older.

    I’m not a fan of the hump if I’m being honest but if I like the fish I may tolerate it.

    Interesting. I love a defined strong shoulder on a koi. Many of the very large Japanese koi have such humps. I think they look great.

    Its a combination if genetics, understanding the blood lines of the koi you’re growing, diet, temperature, pond size, current/flow

    Fish in my pond have around a 30% chance of getting the hump, but that might say more about me than their parent stock LOL.
