A sick Betta fish can often be the result of improper care. All too often it’s easy to get away from the routine procedures that need to be followed in caring for a pet of any kind, and of course a pet fish is no different. Even improperly introducing a Betta into its new home can be a cause of problems not to far down the road. Betta fish can of course contract certain diseases due to various conditions, but sometimes a fish can just get sick or not be in the best of health do to its environment.
