My Crowntail, male Betta fish, Kingston just stares out of his tank all day long. He doesn't move around much and he stares out as if he is waiting for something to happen. Also, I've had him since Sunday and he hasn't eaten at all. I put whole pellets in his tank but he just let them fall to the bottom. Then, the next day, I decided to crush up the pellets. Kingston just stared at the food floating to the bottom. What's wrong? Is there something I'm doing wrong? I really want to have a happy Betta!
