Advertisement My mother's beta fish has apparently refused food for two weeks, and she thinks it is slowly dying. She puts food in the tank twice daily. I am skeptical, given that it appears over-fed (its stomach is distended and food-pellet colored), and I would guess that either it is eating when she isn't looking or it is simply not hungry because of how much it has eaten, but knowing very little about beta fish, I figured I would ask. Perhaps it has an infection in the discolored, bloated area? It has always eaten well before this.
