A 3-gallon fish tank is just a standard size for that. Check out the following suggestion to find out the best 3-gallon fish tank for you or your kids.

Material

Generally, you’ll get a fish tank of 2 different materials. They are glass and acrylic plastic. As usual, you can get a 3-gallon fish tank with any of these two types of materials. Glass tank is better to look at and it makes the water less dirty. But an acrylic tank is less crackable and lighter in weight.

Weight and Design

Generally, a glass tank is heavier than an acrylic tank. The design also matters here a lot. If you buy just a tank, it will be less heavy. But if it comes with different structures with lids and other decorations, it will be heavier as usual. You can find a 3-gallon fish tank with different designs and shape too.

Easy Setup

You should always buy a fish tank that is easy to set up. A 3-gallon fish tank is generally not a very big size. So, there will be fewer Aquarium kits adjacent to it. Besides, many fish tanks provide setup guides. It will make the process easier for you.

Easy Maintenance

A 3-gallon fish tank generally isn’t very big in size. So, it will have low maintenance. But there are some tanks available in the market with a complex design and so, they require high and tough maintenance. So, be aware of that.

Lightning and Filtration

Think if you want a tank with proper lighting and filtration. There are lots of 3-gallon fish tanks that come with a complete package. You can try out one of them. But you will not get any extra lights or filters if you try a fishbowl.

Placement

Think about where you are going to place your favorite fish tank. And then choose the appropriate size and shape. You should buy a tank that occupies less space so that you can place it anywhere and everywhere.
