My guppies upper tail is turning white

[Jake Chet]

Hi i got one of my guppies that is a male about 5 months ago now who is occasionally bullied from other male guppies in my 60g tank but his upper tail is turning white, Thoughts on what this may be? Thanks, side note my tank is overdue for a water change.

No change in texture? No change in behavior? Pictures aren't clear, but it doesn't look to be damaged, so it's likely just a normal change in coloration if there aren't secondary symptoms.

Well, just to be pessimistic (oh no!) the white area looked a tiny bit fuzzy but that may just be from extreme magnification clicking on your pic. If the tissue looks ok, no sweat, there are many guppy variations these days. He may need to grow into his colors including white tipped dorsal (top fin) & white tail area...He's quite pretty!

I have seen fin color changes in male guppies as they mature before. Had a nice yellow tailed delta turn dark.
