Um you know that most guppy names are chosen by the creator of the line? So it is whatever you want to call it. Now if you are asking about genetics then ??? Your notes could tell you more than my guesses based on a picture.
There is some fin elongation but it doesn't appear to be as extreme as Berlin Guppies. Perhaps it is a Giessen finned male. Those don't have the loss of function the Berlin mutation suffers from. The body ground color seems to be like the wild fish, so no recessive gene expression there. He doesn't appear to be albino, blond, gold/bronze, or blue phenotype. Is his tail damaged or naturally that ragged looking?
