So I’ve had this puffer for almost a year and I’ve had him in my big tank for about 6 months and he eats like crazy and acts normal he has had one big spot on his fin that must be lympho because it’s been there for a long time. He has all these little pimples on his back that’s been there for a long time and I am wondering what it could be. It doesn’t look like any disease I can find online.
