Kohaku with secondary hi

[Regenmeneer]

JG,

you were talking about the beni appearing from the center of the scale. This is the case when the next layer of beni is starting to appear. But I've been searching for the name of it for quite some time. Been asking around, no-one seems to know. Maybe this is one JR can help with?

I have a male Sanke on which secondary Hi arose between dorsal and caudal fins along the backbone. He was 4+ years old when it happened. Now 6+ and still there. I think it is actually deepening as he ages, but not enough to make it acceptable.
