How come betta fish lay on the backs bottom?

There are a few reasons why a betta fish might lay on its back at the bottom of the tank.

* Swim bladder disorder. This is a common condition in bettas that can cause them to lose their buoyancy and sink to the bottom of the tank. Swim bladder disorder can be caused by a variety of factors, including genetics, injury, or infection.

* Constipation. Bettas who are constipated may have difficulty swimming and may lay on their backs at the bottom of the tank. Constipation can be caused by a diet that is too high in protein or fiber, or by a lack of exercise.

* Stress. Stressed bettas may also lay on their backs at the bottom of the tank. Stress can be caused by a variety of factors, including changes in water quality, overcrowding, or the presence of aggressive tank mates.

* Old age. As bettas age, they may become less active and may spend more time resting on the bottom of the tank.

If your betta fish is laying on its back at the bottom of the tank, it is important to try to determine the cause so that you can take appropriate action. If you are unsure of the cause, it is best to take your betta fish to a veterinarian for evaluation.
