What to Consider When Buying a 5 Gallon Fish Tank

As mentioned earlier there are several ways to distinguish between fish tanks and they vary from the way they’re built to the way they serve you, your fish, and your current situation. There are different things to keep in mind when making your purchase. 

Before we get into those, you should first know what you’re choosing from in the first place. Don’t hunt for really cheap fish tanks with the thought that you’ll be done easily. A good fish tank needs to be of a certain minimum qualification to not cause unwanted problems that you simply can’t find in a lower price range. I’m sure that you can find some cool fish tanks on your budget too so without further ado:


  • Round fish tank: this one is pretty self-explanatory, they’re rounded like the ones you saw on Nemo and they only serve on aesthetics depending on if you like rounded tanks more. They’re usually called fish bowls.
  • Cube fish tank: Common in households, you can find a cube aquarium almost everywhere you see fish. It has a bit of a more collected build and it also plays a subjective role in your decision.

Design and Material

  • Modern fish tank: If your house or office is big on the minimalist, modern aesthetic this would be the choice for you. Although the majority of the tanks we recommend are modern and sleek and can fit anywhere, Fluval is the brand that is usually big on aesthetics and the latest trends. There’s nothing wrong with the other tanks, it’s just like we said in the beginning, these are just ways to distinguish between tanks, not rank them in any way.
  • Plastic fish tank: Now, people are much prejudiced with this choice, but there’s rarely anything to complain about. Sure, you might get a scratch or two if you’re not careful, but who would even move their tank around with objects that can scratch it on them. If anything they’re a bit safer if you have kids or other pets around. A plastic or an acrylic aquarium has no big difference from a glass one besides maybe the prejudice some people have.
  • Glass fish tank: This is the most popular choice, maybe because stereotypically glass gives off a more fancy vibe. It does weigh more than plastic though and might be impractical on tight spaces with children or pets. However, some people prefer it for its fineness and that’s totally fine considering everyone knows what their house needs the most. They’re generally a bit more expensive but irrelevant enough to not change your mind.


  • Freshwater fish tank: Freshwater tanks are easier to maintain, there are fewer things to worry about and are usually cheaper. They’re great for beginners because they don’t leave much room for error and they’re also useful if you’re not big on variety and don’t have the amount of time necessary to take care of a lot of things at once.
  • Saltwater fish tank: As for saltwater tanks, they do take more time and work for your fish to thrive, but they offer more varieties of vibrant and colourful ecosystems. It’s a great option for people that know what they’re doing and all the sources given for this tank and the fish in it are rewarded by what an amazing marine life it provides. The most challenging aspect for beginners is when setting up a saltwater tank for the first time. 

Tank Kits

Besides all the things mentioned above, there’s something else to keep in mind. When we purchase a tank, it’s important to mind the contents of the box. For an aquarium to deserve that name it ought to come with different accessories that make it functional and ready to use. Things such as the filter, the heater, and the LEDs are almost a necessity to be included in the box with no additional purchase. 

Now, the manufacturer isn’t exactly forced to include all these in the box, but it would be a wise choice for you to always go for tank kits rather than a singular tank with nothing included. If you find the kits expensive, trust us on this, buying them separately is more expensive. It also saves you the time and research to find accessories that suit your tank adequately. 

When you purchase a kit though, everything included is sure to fit your tank with no problem because the manufacturer made them custom to the tank itself so there won’t be any issues like that. A 5 gallon fish tank with filter and heater is basically all you’ll ever need on any occasion if you’re searching for small fish tanks. Tank kits are usually a great choice and even if you don’t like one of the things that come with it, you can always upgrade your tank further.

Our Verdict

Overall there’s not a single product mentioned above that won’t satisfy your needs. With all these options to choose from you won’t have any circumstances you won’t be able to solve. If you’re more into aesthetics, the Fluval Chi will be a great choice for you. 

If you’re on a budget and need something that has everything without breaking the bank, Marina LED Aquarium Kit is the choice for you. The main thing to keep in mind is that all of these products were made to serve you and your fish needs. If you don’t think one won’t be a good fit for your situation, don’t feel pressured just because it looks pretty. Remember that the main concern is the fish and everything is in their function.
