Hi, I have a Betta, named Oscar, who up until I changed his tank today was fine. Now he is floating vertically, with his head towards the bottom of the tank when he isn't swimming around. He keeps rubbing himself against his rocks and the little chest in his tank. He also keeps going to the surface and sticking his face out of the water before diving back down. He's never acted like this and I am worried. I have had him for a little over two weeks.
