Re: black edging on tails and fins
I have some that it is a natural coloration. One thing about goldfish is they do change colors as they age. So its hard to give you a direct answer on this one without knowing other things like tanks levels such as ammonia, nitrite, and nitrate readings. Overall health of the tank, size of the tank, stocking in the tank and such.
Most tail problems are either tail rot or fungus. (which is usually white) so in a quick answer I would say the black was not a issue but I cannot guarentee it.
