I've had my betta for about a year. Up until last week he was in a 3/4 gallon vase with a peace lilly plant in distilled water. His peace lilly died and I was looking to get him a new plant when I stumbled upon this site. I did a little research and decided to upgrade him to a real home. I bought a 4 gallon tank with a filter and lightly planted it. I also got some water conditioner and started using treated tap water. I moved him to his new home 3 days ago but since then he has been acting very odd.
He sits at the bottom of the tank only going up for air occationally. He stopped eating today, and every once in a while he spazzes out and quickly darts back and forth at high speeds like he is running away from something. I think he is sick, but I don't know what to do.
