What is wrong with my Betta fish that has not eaten in two weeks?

Answer by  dubbers (49)

A Betta fish's metabolism can be very easily affected by the temperature of the water in his tank. Fish may not eat if the water is too cold. Other factors leading to a lack of appetitite are buildups of toxins in the water, illness, or old age.

There are a variety of things that could be wrong. It might be as simple as the wrong water conditions, or he could have a disease. This situation is serious, I advise to seek professional help from your local pet shop. Make sure you take some water to be tested.

Try a different food, or try blood worms. If the fish still isn't eating after trying those two things, I would say something is wrong, get it checked out.

the first thing i would check is the water temperature, if its not spot on then they will loose appetite and activity desire, which will eventually lead to death.
