A fish tank can reduce your vital sign. It does sound too good to be true, but it’s true.
Because of the calming effects of the fish movement, a vivarium can help people reduce their blood pressure.
There was researches done to review this effect of the fish tanks. The research proved that a aquarium doesn’t only help reduces vital signs but also a person’s pulse.
There are some cases people like better to decorate their houses with aquariums crammed with water, decorations, and aquatic plants but no fish.
Even though the no-fish aquarium still helps with a pulse and blood pressure, they don’t work further as an aquarium with fish.
