Symptoms: The most visible one is a white spot on his head, just above his right eye, about the size of his pupil. This showed up literally overnight. It wasn't there yesterday.
He also appears to have fuzzy white... stuff, it looks like cotton, on the ends of his fins. It's not very much, but it's definitely there. I have spotted some on the sides of his tail fin as well. I've attached a few images, but the white cottony stuff doesn't show up well in any of them. I thought I spotted some faint fuzz on him a couple of days ago, but thought it went away or that I had been imagining him due to water that needed a change. I don't know if this is that, or something new.
He went through a 100% water change yesterday. I was careful, left his water to mellow overnight, treated it (Nutrafun Betta Plus tapwater conditioner; 5ml/2l), and even added an appropriate amount of aquarium salt (1tbsp/5gal). Before that, he had had one 50% change in the previous week we had owned him, which I now know was too few. He is in a 1gal tank, pending us getting something larger. His water temperature ranges from about 24 to 29 (gets hot in here in the summer!) over the course of the day. I don't have a water testing kit at the moment. I will get one.
He ate well yesterday of rehydrated freeze-dried bloodworm and pellets, and honestly, in terms of looks and behavior aside from the dot and the fuzz, he seems perkier, feistier. His fins were also very clamped yesterday, and have opened up a great deal today as compared to where they were. One strange thing -- the iridescence along his sides used to be much stronger when we got him, and it's dimmed down a little since then.
I have attached some photos, but the white fuzz doesn't show up satisfactorily in any of them.
