Hello friends:
This summer I got whole 2 fry, and one of them has quite nice ginrin, therefore I have kept it.
But unfortunately it developed a black spot on its upper lip, just like the ugly Hitlerīs mustache. It is solid, somehow up-risen, surface smooth, and not very soft. Could not be removed by scraping. What is it? Will it disappear? It is a lot of extra work to just take care of one single fry so I am considering whether it is worth to keep it.
