Aquariums Reduce Stress and Anxiety, and Promote Calmness

Let's face it. In the fast-paced, on-the-go world that we live in today with our endless to-do lists and only 24 hours to do them every day (if you don't eat, sleep, or relax that is), it is very easy to get stressed. Our generation has more documented cases of anxiety disorders, chronic panic attacks, and other health issues related to excessive stress and overwhelm than any other in human history.


However, scientists have determined that viewing and engaging in aquatics (by simply watching underwater environments or by expressing creativity by designing and cultivating your own marine habitat) is proven to significantly reduce not only feelings of stress and anxiety, but also their physical expression in the body.

Our first study (Kidd and Kidd) interviewed 50 men and 50 women in pet stores that sold fish products and found that a majority of pet fish owners reported “the calming, relaxation, and stress-reduction effects of just watching fish which lessened anxieties and created a sense of serenity.”

Another study (Barker, Best, Rasmussen) observed an aquarium’s effect on electroconvulsive therapy (a very invasive and uncomfortable treatment for mental disorders) patients and found an average of 12% reduced feelings of anxiety from those who viewed an aquarium for a few minutes prior to treatment than from patients who did not.

A third study (Cracknell, White, Pahl) conducted at the National Marine Aquarium in Plymouth, England documented visitors’ physical and psychological reactions to viewing a large 550,000L (around 145,000 gallon) tank while restocking it with fish and other marine life. 

What they found was that at all phases of restocking, even just watching an empty tank with the movement of the light through the water and of the artificial seaweed, both blood pressure and heart rate of the viewers dropped.

However, when fish were added, the drops in both blood pressure and heart rate were much more significant, and it increased the more fish there were. Additionally, the mood of the viewers greatly improved due to the number and biodiversity of the fish present in the tank.

Here's a graph showing the average reported states or emotions of the viewers over time. Notice how during all phases of restocking, the viewers became much more calm, content, and positive.

This indicates that not only the number of fish affects a viewer’s stress levels, but also things like varied species, color, size, etc. In short, the more variation, the better viewing experience and positive effect on your mood and body. Keep this in mind when designing your marine habitat.

So...late one night I was shopping online for a new seahorse tank. I ended up on the Two Tides website & in the bottom corner it said to click for a live chat. Since it was after midnight & they’re in the same time zone, I thought no way. But I clicked anyway & sure enough I was chatting with a live person! We chatted for over an hour until he asked for my email address telling me I’d be contacted the next day. That’s when I met Tyler. He helped me with my purchase. He went above & beyond to get me the tank I wanted, even spending a day on a video chat with Pro Clear Aquatics as they searched their warehouse looking for the aquarium I wanted with a blue back. They stopped making these a while back but they found one for me! I absolutely love this aquarium & I can honestly say that Tyler provided THE best customer service I have ever experienced from an online vendor. He told me from the start that he would stay with me from start to finish & he did. He was always there to promptly answer any questions or concerns I had. I can’t say enough about how happy I am with my purchase!

Piece of Art

I was looking for rimless peninsula aquarium to upgrade my 80 Gallon and my 70 Gallon mixed coral reef this year, but had a really hard time finding it because of the coronavirus. So I purchased a ProStar 230 Peninsula from Two Tides and I’m glad I made the right choice. The 3/4” low Iron glass display tank and large glass sump and light weight white stand is just beautiful as a piece of art. Tyler is extremely helpful and responsive and made the process easy and stress free. Everything arrived very well packaged. When we were setting up the tank, we couldn’t believe how easy the setup was with no issues what so ever. If you are looking for a high quality aquarium I highly recommend this company.

Absolutely beautiful fish tank and customer services

I am very happy with my order. The tank is very beautiful of out the box and it was well packaging with feel very safe from shipping damage.

Custom services from Two Tides Aquarium Supply was excellent. I have communicated with Tyler who had assisted me throughout the process from ordering the tank through shipping process, and what to expect on delivery day.

I am highly recommend anyone who want to get a new aquarium, to purchase from Two Tides Aquarium. Best to look for Tyler, he is a very helpful and pleasing person to contact if you have any question. I am glad that I have met him and definitely I would buy again in the future from Two Tides Aquarium supply when I need another fish tank and any other aquarium supply that I may need.

Thank you very much for a beautiful tank.


Great Customer Service

I am very pleased with not only the product I received but the service that came with it. Tyler was in constant contact with me throughout each stage of the process. He answered all questions I had and was even able to provide me with links to plumbing parts I needed for the build. We had a small hiccup with shipping (carrier's fault not Two Tides) but Tyler was able to update me throughout the day. Tyler genuinely cares about his customers and I would recommend the company to anyone looking for their next show room tank!

Great unit

Makes water quickly. Very happy with the unit so far. Pump is quiet, runs great. Finally decided to get a good rodi system. This one has exceeded my expectations way better then any other unit that I've had before. TwoTides Aquarium supply shipped it fast and couldn't be happier with this unit.
