Yup. Black edges to the fins is the sign of too much ammonia in the tank
water. Immediate remedy is do a large water change to get rid of the
ammonia.... 'til you cycle your filter properly.

I think that the OP might want to actually *check* the ammonia levels. My
NewFish has some black on his fins, and my ammonia is at 0. I think it's
just his coloring.

My wife picked our 2nd orange fantail from the LFS tank because of the unique black lining on the edge of its tail.
At least, we thought it was unique.....
3 weeks in our tank and the black color is slowly disappearing (tail becoming fully orange).

Am I to understand that the LFS sold me an orange fantail that had suffered ammonia damage, and is recovering in my tank?

He/she is probably just developing mature coloring. Many goldfish will be
widely varied in their coloring as juveniles, but as they grow up they will
become completely orange. I bought 4 feeders of all different colors and
patterns. Every one of them is solid orange now.

Would a 2mm-wide black lining along the entire edge of my orange fantail's caudal fin and a 1mm-wide black lining along it's dorsal
fin be able to disappear in just 3 weeks as a result of maturing?
I though these color changes take quite a bit of time to develop.

My 2nd fantail (Clinton) is completely orange now and looks just like my first fantail (Carter).
