I think you should read it again. Maybe you missed something around 2015
I'm sorry most of those 11,533 posts are not about fish, but I bet 24 or 30 of them are.
I would have something to write about fish if they got sick, but no matter how many diseases, most of which I have never heard of, I add, my fish just refuse to get sick. I even resorted to painting spots using an old can of "Sears Weather Beater paint" on the fins of the fish, but they just keep wearing off.
I tried cutting off parts of their fins, but they grow back faster than I could take a picture, so I have just resigned myself to having healthy, immune fish.
Maybe I will try feeding some flake food, that should do it.
I also keep going to Petco. I got 3 fish from them in the last couple of weeks, but even that doesn't work.
Some day in the distant future, we will all have immune fish but first we have to think a little harder and not go to too much college.
