Owning a pet has its perks. However, most of the benefits we know are those associated with animals such as cats and dogs. One of the most underrated pets that have many surprising benefits are fish. Have you ever wondered why most clinics you visit have fish tanks in them? It’s because fish have some incredible benefits. Thanks to my visits to the dentist as a child where my fascination and love of fish was born; since then, I’ve come to learn what those benefits are. 

1. Helps manage stress, blood pressure and heart rate

Fish tanks have a way of calming you down. If you go to any high-stress space such as hospitals and offices, you will notice that there is probably a fish tank located somewhere in the vicinity. It’s tough to keep your stress levels up when staring at an aquarium. Additionally, they help manage your blood pressure and heart rate. If you are experiencing a stressful situation, look at your fish tank, and feel your heart rate slowly reduce. Your blood pressure will simultaneously drop, as well. According to research, if you stare at an empty tank with just plants in, your heart rate lowered by 3%, and when fish were introduced it went down by 7%.

2. Helps improve sleep quality

There’s nothing more annoying than not being able to get a good night’s sleep. Owning a fish tank could get you one step closer to curing your sleep troubles. Watching your tank before going to bed will help calm your mind and body helping you fall asleep. A fish tank in your bedroom can also provide you with some white noise, which is known to be instrumental in aiding sleep.

What to consider before buying a fish tank

If you are in the market for a 30 gallon fish tank, there are certain factors you should consider, in order to make the right decision. 


Naturally, one of the most important factors that should be considered is cost and your budget of what you are willing to spend on a tank. The costs associated with fish tanks vary depending on the material used, size, and what’s inside. Therefore, plan your budget ahead of time so that you don’t break your bank when you finally make the purchase. 


Although this may seem obvious, it’s important to consider where your fish tank is going to go. When you buy your tank, you should already have in mind where you’re going to place it. This will help avoid any issues like breakages or plumbing leaks. Where you place your tank needs to be sturdy enough to hold the tank’s weight, and somewhere it will stay safe. A 30 gallon tank will weigh approximately 48 lbs empty. With water, it will weigh roughly 350 lbs.

Type of fish you intend to keep

There are different types of fish tanks for different types of fish. For instance, there are fresh-water fish tanks, marine aquariums, brackish fish tanks, and many others. It is up to you to decide what fish you have and the best type of tank for your fish.
