Is it normal for koi fish to change its body shape as it increases in size? Because I see that juvenile koi area all torpedo shaped, while some adults (mostly large ones) have irregularities in their bodies, such as a large shoulder hump. Are they supposed to retain their overall torpedo shape or are they supposed to change shape?
Now, I am not a fan of shoulder humps on koi fish and would love to choose fish that would not have any. However, how do I know whether or not a juvenile will grow a hump or not?
Thanks!
