My blue betta seems to be going through a colour change (I hope, cause I don't want it to be anything bad). About two weeks ago he got a white spot on his top fin. I thought that it was just a blown tail, which he gets from time to time, but now the whole upper edge of that fin is white, and the front edge of his bottom fin is also white. He's a tail biter, but there's no white on his tail. I've had him since May and this is the first time anything like this has happened.
Here's a pic from when I first got him...
And here's a pic from today...
Anybody able to tell if this is something other than a colour change?
