Fish as an Emotional Support

Fish is an aquatic animal and truly wonderful pet for people who don’t have the time or physical space to give to a higher-maintenance companion animal. One can keep fishes that are pet-friendly in a glass tank called an aquarium.

Have you ever wondered why hospitals, dental surgeries, and waiting reception areas keep aquariums?

Studies have shown that fishes can reduce stress levels up to 10-12%.
Keeping a fish can help you reduce stress, reducing the blood pressure level along with the symptoms of pain and anxiety. Well, many of us are facing several mental or emotional disorders due to our daily life stress.
Not everyone likes to own dogs and cats as Emotional Support Animals. Some of them find peace in watching small creatures floating in the water like fish.

So, those thinking of adopting one must have an eye on the benefits of adopting fish as an ESA and the types of fishes that can be adopted.

Benefits of keeping a Fish

Keeping fish as a pet can add various benefits to your health. There are several mental health benefits of keeping fish. Some of them are as follow:

Reduce Stress:

Fishes help reducing stress and anxiety. Looking at the fishes moving in the water might divert a stressed person’s focus and ultimately reduce the stress level. It also is the color palette of the fishes that can reduce the stress level in a person.

Lower Blood Pressure and pains:

If a person suffers from high BP or other heart health issues, having a fish tank in your home could help you immensely. According to scientific statements, keeping an aquarium in dental clinics can decrease the pain felt during dental procedures and the amount of pain medication needed afterward.

Quiet and calm:

Emotional support animals like dogs and cats can sometimes be irritating as they create a lot of noise by barking and shouting. In contrast, fishes are very quiet and calm aquatic animals and also more suitable for younger families as they are entirely silent.

Got adjust in small space:

Petting an Emotional support cat or dog may require a lot of space as they need more area to hang or wander around. On the contrary, keeping fishes as an Emotional Support Animal requires much less space as you can store them in an aquarium which you can place at one corner of the house.

Inexpensive than Other Pets:

Fishes do not cost much compared to other animals, and keeping a fish is not an inexpensive hobby for pet-lovers. Well, the cost mainly depends upon the type of species you own, and it’s evident that the fancier you go, the more expensive it becomes, but it does not cost as much as the dogs and cats do. Feeding a fish is also much cheaper than other animals as they do not cost much.
