Fish tanks are a great addition to any home. They’re truly beautiful and a real sight for sore eyes. Whenever you’re feeling weary or stressed, sitting in front of a fish tank will help lift your mood and spirits.

If you’ve never owned a fish tank before, it’s best to find one that is suitable for beginners. While they come in various shapes, sizes, and materials, it’s best to choose between nano tanks and mid-sized tanks, especially if you’re still a beginner.

A 30-gallon fish tank is perfect for those who want a mid-sized tank because it won’t take up a lot of space but it will still be big enough to store a lot of beautiful fish.

There are multiple brand manufacturers that make and sell 30-gallon fish tanks. When deciding which one to go for, you need to pay attention to the material the tank is made from. Each material has its pros and cons as well as strengths and weaknesses.

To help you make an informed decision, let’s go through the best 30-gallon fish tanks.

30-gallon fish tank dimensions

The dimensions of a 30-gallon fish tank are typically about 36” L x 16” H x 16” W.

As we already mentioned, a 30-gallon fish tank is a mid-size aquarium. The empty weight of this type of aquarium is approximately 40 lbs, while the weight of a filled aquarium is about 330 lbs.

30-gallon fish tank buying guide

There are multiple criteria you need to take into account when choosing a 30-gallon fish tank:

  • Placement. Before you buy your aquarium, think about the exact location where you want to place it and make sure there is enough room for it. Take the dimensions and weight into account.
  • Lighting. Some aquariums will come with LED lightning. But if they don’t, make sure to purchase LED lighting separately so you can grow live plants in the fish tank. A good light fixture is a necessity.
  • Material. Fish tanks can be glass, plastic, or acrylic, but we’ll talk more about the difference later on.
  • Ecosystem. When it comes to the ecosystem, you will be able to choose between freshwater and saltwater tanks. They come in many subcategories such as coldwater freshwater tank, coldwater marine tank, tropical aquarium, reef tank, and brackish tank.

Types of fish tanks

Now that we’re done with the basic buying guide for a 30-gallon fish tank, let’s explain the differences between the types of fish tanks.


As we already mentioned, the ecosystem in your aquarium can be either freshwater or saltwater.

Freshwater tanks are usually less demanding and easier to maintain, easily transportable, and usually much less expensive than saltwater tanks.

If you’re someone who wants to reinvent the environment of their aquarium on a regular basis, this is centrally a great choice. It’s recommended for novices to start off with a freshwater aquarium since it’s easy to handle and doesn’t require too much work.

Saltwater fish tanks, on the other hand, are usually better suited for experienced fish owners as it’s hard to provide adequate TLC to fish that are living in a saltwater tank.

However, saltwater tanks provide more room for variety and a habitat that is easily adaptable to multiple fish species. This type of environment provides limitless possibilities and is worth the money for those who are after variety.


There are three types of material fish tanks come in: glass, plastic, and acrylic.

Glass is the material that is most frequently used for fish tanks, and a glass tank will always be beautiful and classic. However, glass fish tanks are heavy and have a delicate nature so they’re not suitable for households where they can be knocked over and broken by little kids or pets.

Plastic aquariums are a better choice for households where accidents are more likely to happen, but keep in mind that it’s easy to scratch a plastic aquarium. And while some people believe it’s hard to maintain a healthy aquatic habitat in a plastic aquarium, this is just a misconception.

Acrylic fish tanks are great because they are sturdy and more lightweight than glass aquariums and can be placed on any type of stand. They’re very appealing because they come in various shapes, not just the typical cube shape.


Finally, let’s talk about the different shapes aquariums come in: cube, curved front, and round.

Cube aquariums are the most popular and most common fish tanks. They’re easy to place in any room and they will fit in effortlessly. They have a very polished design, so it’s easy to combine them with any type of interior décor.

Curved front fish tanks are more modern and are often seen as a stylish piece that is wanted by a specific audience. They’re very attention-drawing and easy to maintain, so they’re the perfect combination of style and convenience.

Round tanks have no clear advantage or disadvantage, but they’re usually small and it would be hard to find a 30-gallon fish tank in that shape. This is because round tanks are slippery and hard to handle when they’re larger tanks. Round tanks are typically small and hold only one fish.

So, what’s the best 30-gallon fish tank?

It takes a lot of work and research to find the best 30-gallon fish tank as there are multiple aspects you need to consider. Not only do you have to find one that’s high-quality, but you also have to pick one that fits your needs and your budget.

Our choice is obvious. Seaclear Acrylic Aquarium is the best overall fish tank, but if you want something else, you can also consider other factors such as budget, design, lighting, and so on.

You need to decide what kind of material and shape you want for your fish tank and whether you want to keep freshwater or saltwater fish. All of the fish tanks we talked about here are a great choice, but only you know what is best for you.

How to set up a 30-gallon fish tank

The first thing you need to do is clean your 30-gallon fish tank thoroughly because you can never be sure whether the surface is carrying any worm eggs or algae.

The next thing on your agenda needs to be finding the perfect place to position the fish tank. Ideally, you should have a dedicated spot picked up before the aquarium arrives, somewhere where it will be on full display.

Then it’s time to add the gravel, water, and filter, and make sure everything is functioning as it should be. If you’re transferring any decorations from an old aquarium, make sure they’re properly washed.

After you place all of your decorations, make sure to run a complete nitrogen cycle. You can do this with or without your fish in the tank.

And finally, make sure you have all the necessities:

  • A canopy
  • Enough fish food
  • A fish net
  • A LED light
  • Approximately 32 pounds of some type of substrate. You can use gravel, sand, or aqua soil if you have a planted tank.
  • A 100-watt aquarium heater

What equipment do you need for your tank?

If you want your tank to be a great environment for your fish, you will need to add some additional equipment. But out of all the equipment that’s available for fish keeping, three things are an absolute must: a heater, a filter, and lighting.

Heaters are necessary for any large fish tank, especially if you want to have an aquarium where you can keep fish that prefer warmer temperatures like cichlids or betta fish. If the tank you buy doesn’t come with a heater, you can purchase one separately.

The Cascade Heat 10″ Aquarium Heater is a great choice for 30-gallon fish tanks. It’s long-lasting, dependable, and doesn’t take too much space.

The next thing you will need is a good filtration unit. Filters are usually included with every fish tank, but if you choose a tank without a filter, you will need to purchase one. A good choice is the Fluval U2 Underwater Filter. It has three filtration levels and comes with biological filtration.

And finally, you need a great LED lighting system. If your 30-gallon tank doesn’t come with one, we recommend the AI Prime 16HD.

What fish should I put in my 30-gallon tank?

Which fish to put into 30 gallon fish tankImage source: Pixabay

The species of fish you will put in your 30-gallon tank depend on whether you want to keep freshwater or saltwater fish and if you want your fish to be aggressive or community.

If you go for aggressive ones, keep in mind that your fish will need more space for themselves, unlike community fish which should be kept in pairs or schools.

Aggressive freshwater fish

  • Tiger barbs (Puntius tetrazona)
  • African Butterfly Fish (Pantodon buchholzi)
  • Cichlids – convict cichlids, angelfish, and firemouth cichlids
  • Puffers – dwarf puffers, figure 8 puffers, and red-eye puffers

Freshwater community fish

  • Zebra danios (Danio rerio)
  • Cherry barbs (Puntius titteya)
  • Platies (Xiphophorus genus)
  • Rasboras – galaxy rasboras, chili rasboras, and harlequin rasboras
  • Tetras – rummy nose tetras, ember tetras, and black skirt tetras
  • Catfish species – bronze cories, panda cories, and pygmy cories

Aggressive saltwater fish

  • Eel – dwarf morays (Gymnothorax melatremus)
  • Puffers – mimic saddle puffers, and saddle valentini puffers
  • Damsels – three stripe damsels, three spot domino damsels, and blue damsels

Saltwater community fish

  • Gobies/blennies – neon gobies, yellow watchman gobies, algae blennies, and bicolor blennies
  • Clownfish – snowflake clowns, ocellaris clowns, and percula clowns
  • Cardinals – pajama cardinals and Banggai cardinals
  • Firefish (Nemateleotris genus)

How many fish can I put in a 30-gallon tank?

The number of fish you can put in your 30-gallon fish tank will depend on the species you choose to keep. While it’s not exactly a small tank, you won’t be able to go too overboard.

Freshwater aggressive fish require a lot of space and shouldn’t be kept in large numbers. A 30-gallon fish tank is only big enough for one or two freshwater aggressive species. If you want to keep more, you should look into bigger tanks.

If you choose to have a community freshwater tank, you’ll be able to keep a variety of species. However, keep in mind that most freshwater community species have to be kept in schools so you might not have a lot of room for biodiversity. But if you like small schooling fish, you won’t have any issues.

Saltwater aggressive fish need even more space than freshwater aggressive fish and it’s hard to find a species you can keep comfortably in a 30-gallon fish tank. But the ones we mentioned above can work. And once again, keep only one or two per tank.

Finally, with community saltwater fish, you will be able to keep five or six in your 30-gallon fish tank.

Final thoughts

If you’re someone who hasn’t owned fish before or you just want a decently sized aquarium that won’t take too much room, you can’t go wrong with a 30-gallon fish tank.

Before you buy your dream aquarium, you need to take all of the things you read about here into consideration. Think about the size and weight you want, what material you want your fish tank to be made out of, the ecosystem you’d like, and whether you’re a bigger fan of fish that is freshwater or saltwater.

All of the 30-gallon fish tanks we listed in this article are great in their own way. All that’s left is for you to make the right choice. And don’t forget the fish food!!
