Well at least you'll be able to find out for sure which variant it is. Considering that if that species is fairly rare in Denmark , you'll have an easier time finding the fry homes. Maybe even may a little cash of them. Seeing the close ups of the fish you have, I'm certain that they are H. carpintis . Can't tell you which variant , but you'll be able to get that info in a week. Anything we could tell you about that right now would just be guesses. At any rate they'll be good looking fish.
