Answer
The black is nothing to be concerned about. Glod fish change color alot. As a baby they start out silver and black. But as they get older they change to gold and from there some(as did mine) got black on their fins and tails. But dont worry the fish wont die and wont turn all black. The black just makes it  unique.
