Here is an excellent article describing the differences between these, and how to treat them: http://www.americanaquariumproducts.com/columnaris.html
It looks like that except there is only one little spot on his side and it's on the fins and, so far, not AS fuzzy. I was beginning to think it was Columnaris since the AQ salt hasn't worked yet...
(which worries me because the other day I had to treat another betta who had fuzzies, but the fuzzies are all gone and he's fine. hope it was just fungus..)
Now that I look at him, he looks like he's getting a saddleback... looks like it's time to go get maracyn 2.
