I just removed my Betta from his 10 gallon, because he wasn't moving, just lying halfway under a starfish. He looks disgusting. He was pink/purple, and now he's gray. I haven't been feeding him, but he's still bloated. I just treated him in a separate tank, along with the 10 gal with this stuff. I did the 10 because I have 2 mollies in there, and one has developed mouth fungus. I feel so bad making him suffer, but I'm hoping he can pull through.
