My male veiltail betta has what I'm pretty positive is a fungal infection. I'm keeping him quarantined in warm water, (80 degrees) treated with salt and melafix. I'm also feeding him a mix of blood worms, hikari brand granules, and freeze dried shrimp flakes. He isnt looking any better, and it's been several days. But he is eating, and he is moving around, just pretty slowly. What else can I do to help him heal faster??
