Fish contain polyunsaturated fatty acids also called omega 3. These omega 3 fatty acids are extremely important for eradicating cardiovascular diseases. Besides that omega 3 fatty acids can be used for Breast cancer patients. It is helpful in lowering blood cholesterol level and blood pressure.
Many people see fish tanks as therapeutic. The sound of bubbling and running water tends to calm people. Fish are quiet, and they are often times brightly colored, which is asthetically pleasing. Watching fish swim can also have a kind of relaxing, hypnotic effect. As pets, fish tend to be low maintenance. You don't have to walk them (obviously) or play with them. As long as you keep their tank clean, make sure their water is constantly being filtered, and feed them regularly, they are simple animals.
