So I have a white iridescent double tail male. And lately, he's been losing his tail whiteness. I thought he has tail rot at first, but then i realized his actual physical tail wasn't leaving, it was that the white was fading out and now the tips of his tail are completely iridescent and clear, you can barely see them.
Is this something I should be worried about, or is it part of him color changing in a good way? He acts fine, eats fine, he has gained some color on him since I got him from the store, he's got a little more black spotting but the clear white tail is confusing me.
