To the greatest extent, success in your aquarium hobby will highly rely on the choices you make when starting out. Hence, it is crucial to pick the best fish tanks for beginners in order to properly maintain the type of aquatic environment that you wish to keep and grow.
In line with this, it is crucial to provide the aquarium with the required equipment and adorn it as per your preference prior to adding your pet fish and other aquarium occupants. As you know, aquariums come in distinct sizes, price range and shapes. Also, they are manufactured using different materials.
So, prior to the shopping proper, it would be more practical to be insightful of the distinct options that are available on the market today. And, if you are uncertain of what to do and where to begin, then this post will help you as you get started.
Buying your first fish tank can be an overwhelming experience for most people. However, it’s much more simple when you understand the crucial factors. Here’s a look at some of them to help provide you with a solid starting point:
- Filters: Your tank will need an effective filter to help clean the water and keep it contamination-free. Most manufacturers offer a starter fish tank with a filter to ensure everything is clear.
- Fish Tank Heater: Anyone who intends on keeping tropical fish needs a tank heater to keep the water warm. So these buyers should prepare to spend more money than beginners with non-tropical fish, such as danios – one of the most popular aquatic pets in the US and UK.
- Lighting: Several lighting types are suitable within an aquarium setup. Selecting one of these types can be a pain, but it’ll usually come down to appearance, cost, and size. In most cases, people often settle on the traditional blue LED light.
- Type of Fish: One-factor beginners often overlook is that a tank doesn’t necessarily accommodate all types of fish. For instance, while biorb tanks are suitable for tropical freshwater fish, they aren’t compatible with fish with a high bioload.
Therefore, always double-check whether the tank is recommended for the specific type of fish you intend to keep.

What to Look for When Buying a Fish Tank for Beginners
Since there are countless of fish tank starter kits products and options to select from, don’t allow them to discourage or overwhelm you. You can create a safe, clean and comfortable haven for your pet fish if you take the following buying guides into account:
- Fish Filter. This helps provide tank water with 3 different kinds of filtration namely: biological, chemical and mechanical filtration. All these help in cleaning the tank water and making it free of any contaminants, chemicals, bad odor and discoloration. This is also to allow the emergence of beneficial bacteria that could help your fish and live plants to thrive well inside the tank.
- Air Pump. The flow of water is quite crucial in that this assists in encouraging gas exchange between the water and the air. Using an air pump, you can keep the water oxygenated which helps fish breathe properly. Moreover, this ensures that the tank water is heated fairly and wards off stagnant water.
- Water conditioner for your pet fish. This does a good job of protecting the aquarium with the precise types of bacteria needed to disintegrate and digest the ammonia discharged as waste by the fish tank occupants. As you might already know, ammonia is hazardous and a buildup of it in aquarium water could exterminate your pet fish. By using the right fish conditioner, you can push your system’s bacterial settlement and inhibit the toxic accumulation from taking place.
- Substrate. This is not merely for the aesthetic side of keeping an aquarium. This serves as the breeding ground for good bacteria to emerge. So, if you are eyeing to grow plants that need covered roots, the substrate is especially required. You can pick from a broad array of colors, sizes and shapes of substrate for your system.
- Fish tank heater. If you intend to keep tropical fish, a heater is necessary to keep the water constantly warm. This will help your fish feel more comfortable and less likely to feel stressed. Certain requirements differ hinging on species; however, the standard range for tropical fish is between 75 to 80 degrees F.
- Aquarium test strips. It is important to monitor your tank water for nitrate, nitrite and ammonia. Test strips help in gauging the alkalinity, hardness and water pH of your tank water.
- Lighting. Various types of lighting selections differ in appearance, price range and size. Thus, it is essential to determine what works for your entire aquarium’s appearance and your budget. Luckily, LED lights tend to last longer as compared to conventional CF bulbs.

Frequently Asked Questions
What size fish tank should I get?
Size is one of the first considerations when buying a beginner fish tank setup. After all, there’s a massive variety ranging from 1-gallon fish bowl tanks to 50-gallon aquariums. It’s easy to see how someone may get flustered by the number of choices.
Most beginners choose smaller options because they think it’s less responsibility. But this line of thinking needs to be revised. For instance, a 1-gallon tank doesn’t offer enough versatility or variety to keep most newbies engaged.
As a result, experts recommend newbies get an average-sized tank of at least five gallons. I’d even take it a step further and suggest a larger option like Tetra 20-Gallon Complete Aquarium Kit. It’ll provide much more room to get completely invested in this new hobby.
But it doesn’t mean a 1-gallon or 2-gallon tank can’t meet a beginner’s expectations. It’s why I included a few of the coolest 1-gallon and 2-gallon options on my list, such as Koller Products’ AquaView 2-Gallon 360 Fish Tank.
Which fish is good for starting a fish tank for beginners?
Selecting a starter fish for beginners often comes down to them being low-maintenance. After all, no newbie will want to start with a fish that requires constant attention. So I thought it’d be most suitable to provide a few examples of low-maintenance fish for dummies:
- Betta Fish (must be housed only)
Of course, these fish aren’t the only low-maintenance ones. But it’s rare to find any newbie who’s had a bad experience, even on Reddit, with these choices. So I wouldn’t hesitate to suggest them as the ultimate choice for parents setting up a fish tank for kids.
Why do I have to wait 24 hours to put fish in the tank?
The 24-hour grace period is a necessary part of a tank’s setup. After all, it allows your tank time to eliminate chlorine and cultivate healthy ammonia/nitrate levels. So your fish will enter the enclosure in a suitable environment for thriving.
But remember, this 24-hour period is only a guideline. So it’s essential to test your tank’s water before and after this period before adding any fish to ensure all the levels (nitrate, ammonia, and chlorine) are close to zero. Otherwise, you could put the fish’s lives in unnecessary danger.
What is the easiest fish tank to maintain?
Generally, a larger aquarium for home use is easier to maintain than a smaller one because big tanks are less susceptible to change. So a 16-gallon or 20-gallon tank would be much simpler to keep stable than a 1-gallon tank, no matter how cheap or expensive.
Therefore, I’d choose Coralife LED BioCube Aquarium Fish Tank Kit or Tetra 20-Gallon Complete Aquarium Kit among my list. After all, both tanks have larger capacities that don’t involve complicated or unnecessary cleaning procedures.

Take note that a fish tank filled with gravel and water weighs roughly ten by up to twelve pounds per gallon. Hence, it is necessary to put the fish tank on a balanced and flat surface and see to it that there is a nearby electrical outlet.
- Do not put the fish tank close to an air conditioner or any source of heat.
- As much as possible avoid putting the aquarium under the direct heat of the sun. Partial or full sun exposure could bring about excessive algae buildup.

It is highly recommended to fill the fish tank with water at room temperature. Indeed, it is also vital to medicate the water with a de-chlorinator prior to adding it to the fish tank.

- To avoid fish stress or shock, it is important to change old water with new water of about the same temperature.
- Keep or store the towels, sponges and canisters that you use when cleaning your aquarium. They must be used for this purpose only and not for cleaning other stuff. This ensures that you don’t add any dangerous contaminants to the fish tank system.
