Health Benefits of Keeping Fish 

Keeping an aquarium can benefit your health. For example, it can help reduce anxiety and stress. Not only that, but studies have shown that it can lower your blood pressure and heart rate.

That’s not all—it also has calming effects, which can help you sleep. Given that, it’s not surprising to know that so many people have pet fish!

4 Types of Fish Tanks to Consider 

There are various types of fish tanks, some of which are easier to maintain than others. Here are some of the most popular ones.

  1. Coldwater Aquarium 

Coldwater aquariums are exactly what they sound like—that is, they’re filled with cold water (below 70F).

There are various types of fish that you can keep in these tanks including goldfish, loaches, and danios. Shrimp and crayfish are good options as well—just don’t keep them together!

  1. Freshwater Tropical Aquarium 

Freshwater tropical aquariums are the “standard” when it comes to fish-keeping. Generally speaking, they’re much easier to maintain than other types of tank. This makes them suitable for beginners.

There’s a vast selection of fish that you can choose from as well. Some examples include guppies, barbs, corydoras, tetras, and mollies.

  1. Marine Aquarium

Marine fish require you to keep a saltwater fish tank. Not only are they more expensive, but they’re also harder to maintain. For this reason, they’re recommended for experienced fish keepers.

Aside from fish, you can also add corals and invertebrates to the tank. Popular choices include crabs, shrimp, and snails.

  1. Brackish Aquarium 

Brackish aquariums are a hybrid between freshwater and saltwater. This type of water is usually found in rivers, streams, and swamps, where saltwater mixes with freshwater.

As with marine tanks, they’re generally difficult to maintain. For one thing, you have to add marine salt to the tank to achieve the desired salinity—something that can be hard for beginners.

Fish that are naturally found in brackish waters would do well in such an aquarium. Some species such as mollies and guppies are also able to tolerate high salinity levels.
