How to Pick the Best 30- Gallon Aquarium For You

If you’re a beginner in the fish tank hobby, you might be wondering what to look for when buying your first 30-gallon fish tank. We have gathered a few key pointers that will help you choose the perfect aquarium for your needs.

Size and Shape of the Tank

With the advent of reliable materials, like acrylic, 30-gallon fish tanks come in a variety of shapes and sizes, such as

  • 30-gallon long tank: 36 1/4 x 12 5/8 x16 ¾
  • 30 gallon breeder tank:  36 3/16 x18 1/4 x12 15/16

Aside from the standard rectangle, you can find bow front, hexagonal, and even fish bowl-shaped aquariums! If you are a novice aquarium enthusiast, a rectangular prism is the best option because it provides plenty of space for your fish to establish territory and swim. However, if you want something unique or don’t have enough space, go for a fishbowl instead!

Choosing the right material for your 30-gallon tank can be difficult. Be sure to weigh all your options before deciding so that you can choose the perfect tank for you.


Glass tanks are the standard for fish enthusiasts with the following advantages.

  • It does not show scratches easily.
  • You can choose any decorations or equipment for your tank because none of it will damage the glass enough to be visible.
  • They are dent-resistant and, therefore, will last longer than other materials.
  • Glass is glossy, which provides a clearer view of your fish tank contents.
  • It is an affordable option for those looking to invest in a long-term solution.


Acrylic is another material widely used in 30-gallon fish tanks with the following advantages.

  • Its main advantage over the competition is that it is lighter and easier to move.
  • It would also require less of the tank stand.
  • Acrylic 30-gallon tanks come in various shapes, not just the boring old regular ones.
  • It’s more resistant to impact and, therefore, safer.


A 30-gallon aquarium is by no means the largest you can get for your home, but it’s still considered a great size that will take someplace in your home. For example, if you went for a tank that was 23 x 17 x 18 inches, your fish would have plenty of space to swim around.

Additionally, remember that you’ll need extra space around your tank to accommodate cords and equipment, like a hang-on-back filter. So make sure you have enough room in your chosen location for everything, plus leave some wiggle room for aesthetic purposes; the placement should also be out of direct sunlight and away from areas with high foot traffic.


If you want a 30-gallon fish tank, all-inclusive kits are available, but they are more expensive than lower-capacity aquariums. To save money, it’s often better to buy just the 30-gallon tank and then get other equipment like filters and lighting separately. Just remember that for larger tanks like this one, invest in high-quality filtration and lighting systems.


A key distinction often overlooked when choosing a fish tank is warranty coverage. Some brands might offer cheaper tanks, but they aren’t as tough. On the other hand, some more expensive tanks come with a better warranty. The extended warranty reinforces the brand’s confidence in its product and provides additional protection for you down the line.


With so many options, choosing the best 30-gallon fish tank for your needs can be tricky. But don’t worry–we did the hard work for you. The tanks we recommend in this article are some of the best available options for your fishy friends!

Before purchasing your 30-gallon tank, remember the important factors mentioned in this post! With this knowledge already under your belt, you’re halfway to success. Learning about these fish tank facts will ultimately lead to a more positive experience while collecting tanks.

Frequently Asked Questions

How Many Fish Can You Put in a 30 Gallon Tank?

As a general rule of thumb, for every gallon of water in your aquarium, you can have one inch of fish. So, if you have a 30-gallon tank, that means you could theoretically have up to 30 inches of fish in total. For instance, 15 two-inch neon tetras would do well in a space like that.

Is a 30 Gallon Tank Big Enough for an Oscar?

A single Oscar Fish can grow up to 12 inches, so you will need a 55-gallon tank at the bare minimum. If you want more than one fish, take into account that every new addition needs 20 to 30 gallons extra, meaning that two fish would require a 75-gallon tank.
