I have had my betta for almost a year now. He hadn't been doing so well. He was very inactive for quite some time. So I moved him downstairs where there was more activity and he seemed much better. I decided to bring him on the three hour trip up to school, which he has survived no problem before. A few weeks after the trip he has started to be really inactive. He's been acting this way for about 2 weeks now. He won't swim and it actually looks like he CANT swim upwards. I feed him and he wont eat. He can't swim, nor will he eat. I have never seen him in this state before and it worries me. Is he dying? What can I do to make him better??
