Nowadays, owning an aquarium is no longer strange to everyone. Depending on their needs, fish farmers can buy different types of fish tanks to serve themselves and their fish. For large fish needing a lot of living space or a lot of fish at the same time, I recommend that the owner use a 20-gallon fish tank.
Why do I say it suits the above cases? You know, 20 gallons is the right size, not too small like a 1-gallon aquarium and not too big to occupy the entire area of the room. Today I will review some 20-gallon aquariums that I think will help you in your search.
Why You Should Choose a 20-Gallon Fish Tank
First, we have to talk about the benefits of a 20-gallon fish tank. As mentioned above, a 20-gallon fish tank deserves to be home to some medium-sized fish, active fish that need a lot of living space and those who raise a lot of fish.
In addition to the following 20-gallon aquarium products, you do not need to worry about its origin and quality because they are all products I have used. Another noteworthy point is that some aquariums that are about to be introduced below are some types of a starter kit. A set of beginner fish tanks includes all the necessary items for a freshman to initially take care of his fish. It includes water filters, heaters, net, fish food, light bulbs, and some other essential items. Don’t miss your time, here are some of my favorite products until now:
Here Are the Best 20-Gallon Fish Tanks On The Market

Tetra 20 Gallon Complete Aquarium Kit deserves the best beginner aquarium set. I bought this tank for my two sons because they seem to be interested in raising glofish lately. Actually, I did not expect very much for such an initial kit, but you know what, I was wrong! It has all the accessories, I really like the bubble machine of this tetra 20-gallon fish tank. Watching fish swimming in the water and small bubbles make me feel relaxed.
One thing I like about this tank is its LEDs. Glo fish has basically been able to have its own glow, but under the blue light mounted on the poolside cover, it makes the fish more gorgeous than ever.
About the filter, you won’t need to worry about the noise coming from the water filter because this is almost quiet! The heater of the aquarium also works quite well. Although it cannot regulate the temperature itself, it seems that my fish doesn’t mind this problem. However, if you buy this aquarium kit, you need to buy more decorations and gravel because it doesn’t come with the product. But I think it will not affect your fish farming experience.

The water filter is excellent, it is completely silent, the quality is relatively consistent with the cost of this cheap 20-gallon fish tank. It seems that the filter adjusts the water flow quite well, my fish can freely struggle without fear of water being too strong or too weak. I cannot comment on this filter because I decided to replace a better filter for the aquarium.
About the LEDs, I think it is quite cool to be able to light continuously with high intensity but it would be better if the manufacturer lowered the brightness or perhaps changed the color. I think a small modification would be better for the creatures living in the aquarium.
Other items that appear to be more beautiful in the picture, I appreciate the quality of this product.

Even when filled with water, the aquarium still has enough capacity and does not leak.

The glass can be said to be more durable than many of my previous broken aquariums. LEDs are perfect, it shines blue light instead of ordinary white light.

Structurally, the aquarium has a large rectangular box-shaped water tank and a natural filter. At the filter, you can plant any plant as long as it is suitable for the fish tank environment and does not harm the fish in the tank.
Water filtration mechanism of the fish tank is a closed mechanism, fish and aquatic animals in the tank discharge waste. These wastes are an important source of nutrients that are absorbed by the roots and transformed into energy for growth and development of the plant. From there the plant releases oxygen to purify the air in the house. A special feature of this method is that we allow water purification to take place completely naturally, without plugging or needing a battery to maintain.

I ordered this 20-gallon fish tank online, and it came much earlier than expected. This tank seems to be higher than my imagination.

9. The Red Sea Max Nano Aquarium, 20 Gallon
Buy it now
The last 20-gallon tank in the main review list is the Red Sea Max Nano Aquarium. Last but not least, this product meets all the advantages that few aquariums can have.
Modern design is the first impression I have for the tank. LEDs mounted far away from the tank create a sense of ventilation, lightness, and aesthetics. It has amazing performance and can light up for hours. I do not encourage you to grow corals in the tank. It seems that the light emitted from the LEDs causes certain damage to some aquatic species.
The filtering system is still great as usual, you can use the new filter, but don’t underestimate the included filter. Not producing noise and controlling water flow well makes me believe in the quality of this product completely. However, you may need to purchase your own heater. The product does not come with a heater.
For many aquarium hobbyists, in addition to selecting good and valuable fish varieties, a 20-gallon fish tank is also a contributing factor to the aesthetic value of the home overall. So choosing a reputable and quality aquarium is one of the most notable issues.
Consider fish tank shape and tank position
The shape of the aquarium plays an important role in decorating office buildings. A cylindrical aquarium can be placed in the center of the room. While with boxy fish tanks, consumers tend to put it in the corner of the room, etc.
Quality of accompanying products
Fish tank products for beginners often come with sets. This brings many benefits and also some limitations. Usually, a kit will be attached to the water filter, water conditioner, decorations, gravel, LEDs, etc.
Consumers need to check carefully and read the specifications of each product to know more about the product they are about to buy. In terms of filters, a good filter is a filter that controls the flow of water steadily, without causing too much noise and, importantly, the ability to filter water to clean the tank well. In addition, the attached LEDs also need to check the parameters carefully, some types of lamps show off too strong types of light to harm fish and other creatures in the tank.
Reliable address provides quality fish tanks
You should choose to buy products from well-known brands to ensure product quality. However, not all products from well-known brands are good, before choosing to buy you should prioritize these two above factors to buy the best 20-gallon fish tank. Shouldn’t ignore other products on the market, some brands of aquariums, although they have not created a foothold in the market, they also have quality products comparable to popular products.
How Many Fish for a 20-Gallon Tank?
In fact, choosing how many fish to keep in a 20-gallon fish tank depends on many different factors. For example, in terms of temperament, it is not advisable to combine too many predatory or aggressive types of fish, not allowing peaceful fish to live with aggressive predators. In terms of pH and temperature, tropical fish are often able to adjust themselves to different pH levels, and they can also live well at room temperature. Do not try to combine fish that require different temperatures.
On the other hand, some fish are only solitary, you should only keep them in pairs or small groups. Some community fish species need to be raised in bulk to reduce stress.
Top Fish for a 20-Gallon Aquarium
Some of the top fish for 20 gallons can be listed as Molly Fish, Cory Catfish, Dwarf Gourami, Neon Tetra, Zebra Danio, Fancy Guppy, Otoconclus, Harlequin Rasbora, etc.
Setup Ideas For Your 20-gallon fish tank
Your own 20-gallon fish tank setup is an interesting process. You can see for yourself the change from an incomparable transparent glass tank to a comfortable home for fish.
After choosing the right fish to raise, to complete the process of setting up the aquarium you need to pay attention to the following issues:
PH: You need to find out how much your fish fits with the pH to adjust it best.
How to put fish into the tank: Not just simply drop fish immediately into the aquarium, it will easily stress and die. To avoid this situation, you need to be prepared before releasing the fish. The easiest way is to put a nylon bag with fish into the water and gradually add the aquarium water to the bag. So fish can adapt to the environment better.
Ornamental plants: you can plant aquatic plants or just a few fake plants to beautify the lake. I think investing a living tree would be better for filtering air in the tank. Fish love to hide and play with plants too.
Decoration: You can decorate anything you want, as long as it matches the living space of the fish, not too narrow. Make sure the above decorations do not contain toxic ingredients for life in the fish and plant before dropping it into the aquarium.
How many average size fish can be housed in a 20-gallon fish tank?
For medium-sized tropical fish, like a goldfish, I recommend you only raise one fish. Goldfish is a type of fish that needs special care for it, the speed of water contamination is very fast and they require lower temperatures than other tropical fishes. If you breed benign tropical fish, one or one pair can be kept. Too much restraint should be limited, it can lead to a shortage of living space.
How would you recommend moving with a 20-gallon fish tank?
First, you need to plan exactly what to do to move the aquarium. Locate the tank, remove the water filter and heater first. Pick up the fish and drop them into a nylon bag and put it into the insulated box. Take out the ornament. You only need to flush 2/3 of the water in the tank, keeping good bacteria inside the water.
After moving the aquarium, you release the pebbles beforehand, fill up the chlorine water immediately. Then attach the filter and decorations back to the tank. Wait a while for the heater and filter to work again and drop the fish. Watch the aquarium every day for the first week to make sure everything is normal.
I hope with these experiences you can find the right aquarium for your own. A fish tank that meets the above criteria will help fish live healthier and longer. On the other hand, a durable and beautiful aquarium is always the best decoration for your work and living space.
