Also, why does my betta lay at the bottom of the tank? One reason your betta might be lying at the bottom of the tank is if you don't have a filter in your tank.

When ammonia builds up too much your betta could begin suffering from ammonia poisoning, which can quickly become fatal.

The ideal pH for bettas is 7 or slightly more acidic.
