My daughter who is 8, used her birthday money to buy an aquarium and betta. She ended up buying 2 females and for the first couple of weeks, things were great. Then the blue betta stopped eating much and about 2 weeks later, she died. Our red betta (the one I am writing about) still seems very active and eats well. No changes in behavior. But a few weeks ago, we noticed that she had a white spot on her head (see pics). We assumed it was a fungus and treated it as such (twice) but the white spot continues to slowly grow. It is smooth and seems to have scales so it doesn't look like the pics I have seen of a fungus. Overall, her color has also faded quite a bit. We started adding aquarium salt about a week ago with our water changes. My daugher is very worried about her fish, but I can't find any ailment that seems to match what is happening with the little thing. Any ideas would be appreciated. Maybe we should have started with goldfish - we are very new to aquariums and raising fish.
