Hello! I am new here. I got a pretty blue betta called Lucky two weeks ago, and he has seemed fine and very active and he has been eating without a fuss (which is apparently sometimes a problem). I noticed about a week ago that his fins were beginning to show some white on the very tips. I watched closely and it is sort of hard to tell whether or not the white is spreading, but if it is, it is certainly doing so VERY slowly. Could this be a disease, or could it be that his colors are developing (I got him in a pet store, so he was probably pretty young)?
I tried searching for white fins and other keywords, but I got a lot of results that didn't seem to match. Thank you so much!
