Fish in particular and most aquatic animals, in general, cannot live without water. People who want to take these animals as pets or decorate their homes need to drop them into tank-shaped aquariums that nearly complete their normal living conditions in the wild. That’s why the small fish tank is so important to fish owners.
A good aquarium with a water source contains many convenient nutrients for fish to grow and sustain life. Fish tanks also help owners to take better care of their fish.
For me, a good or bad aquarium is judged on many aspects such as transparent glass material, water filtration system, heating system, size, etc. So what is the best product?
Today I will share you the best small fish tanks based on my experience:
1. Tetra LED Half Moon Betta Aquarium, Betta Fish Tank
Buy it now
Tetra LED Half Moon Betta Aquarium so far has been my best small fish tank. This fish tank has a special shape, semicircle.
I especially like this creative way of the manufacturer because it deserves to be a great decoration for my office. With such a semicircle shape, I can observe the whole vivarium as well as my betta.
Transparent plastic also makes me love the aquarium more. This one can be easily cleaned if it is dirty. That’s great, isn’t it!
In addition to the unique shape that brings high aesthetic, the aquarium also comes with decorative LED lights. What I like when lighting the LED for the aquarium is that it is completely on the outside, not shining straight into the fish, which affects their health.
However, also due to this special shape of the fish tank, large decorative can’t fit it. But don’t worry, depending on the shape of the ornament, you can fit some to your small fish tank.
2. AquaView 2.5-Gallon Fish Tank with LED Lighting and Power Filter
Buy it now
The first time I bought betta that was just over 1 inch in length, the first thing I know is to find him a perfect home. Walking in the pet shop and I finally saw it, AquaView 2.5-Gallon Fish Tank.
With 2.5 gallons, it is the right choice for my fish friend. The aquarium is not so small that my fish does not have enough living space, and it is not too big for my friend.
I like the way light colors are changed into blue when shining on the aquarium. Everyone knows fish loves blue.
It’s great because the aquarium comes with a water filter. You know, pet owners usually pay at least half of the price of a fish tank to buy a filter. In addition, it also included diverter water to avoid the fish having difficulty going upstream.
Now my friend has a perfect home. I am completely satisfied with this aquarium.
3. MarineLand Contour Glass Aquarium Kit with Rail Light
Buy it now
I have to say that the MarineLand Contour Glass Aquarium is my best product ever. Why do I promote this fish tank like that?
The first thing that appealed to me was the transparent glass of this product. The curved edges of the glass impressed me a lot. Transparent glass can observe the whole scene clearly. Also cleaning the glass is quite easy, which helps me save a lot of time cleaning every day.
Usually, I do not appreciate the cheap small fish tanks because of the quality and its appearance is not very good. But I changed my mind when using this aquarium.
I decorated it with a few branches of plants and a few small rocks, the plants seemed to adapt quite well with low light emitted from the aquarium lights.
The decoration cost is not even expensive, but thanks to the transparent glass, the small fish tank brings a sense of elegance and cleanness.
Light trips of this aquarium have two modes including day mode and night mode. You can completely adjust the time to change between the two modes. The right light change makes my fish much more comfortable.
Believe me, some aquariums have practical LED lights that are quite uncomfortable for users and their fish because of inappropriate brightness.
4. AquaView 6.5-Gallon Fish Tank with Power Filter and LED Lighting
Buy it now
First of all, the fish tank is made of non-acrylic plastic, so be careful when you are holding or moving the aquarium.
In return, it has an elegant and highly decorative appearance. Overall, AquaView 6.5-Gallon Fish Tank looks quite beautiful and worth money with new unique designs.
Although the aquarium only has 6.5 gallons, I feel it’s bigger than the real capacity. Usually, with a vivarium like that, I can put in 6 to 7 fishes, each about 1 inch long.
LED lights are plugged on the outlet, it emits blue light to beautify the entire the small fish tank and helps fish adapt better.
Regarding the water filtration system, I was really impressed with its operation. Sometimes I don’t know if it’s running because I almost don’t hear the noise coming from the filter.
Still, it does a very good filtering function, I appreciate this. Also, the water flow is very calm. This keeps the fish from having any problems when swimming.
5. GloFish Aquarium Kit w/ Hood, LED Lights and Whisper Filter
Buy it now
GloFish Aquarium comes in two sizes including 3 gallons and 5 gallons. You can optionally choose any size according to your needs. I favor 3 gallons more because of its compactness.
Fish tanks are decorated in my office, if you like, this one can only be decorated at anywhere from bedroom to the living room as well. About light, both versions have equal brightness, not too dark and not too bright.
This vivarium is made of acrylic so you may encounter the algae accumulates situation. In that case, you should use a specialized algae cleaner to have a clean small fish tank surface.
Placing the aquarium in the desk completely doesn’t affect me. The water filter of this product almost doesn’t make noise. Its water filter feature is also very good. I just need to clean the aquarium occasionally, the rest has a heater and the water filter works.
If you don’t like the 3-gallon aquarium because it’s too small, it’s okay. Some people like to own an aquarium that is not too big but not too small, I recommend they buy a 5-gallon aquarium or more.
Don’t miss the list of 5-gallon Small fish tank with filter and light for more details. If 5 gallons are still not big enough for you, the list of 10 gallons fish tank with filter and light will meet this need.
6. Fluval Spec III Aquarium Kit
Buy it now
I really like the water filtration systems of Fluval Spec III Aquarium. The sound of water purification is almost quiet, the only sound I hear is when the water level in the tank is lower than the filter.
Above the aquarium, there is a transparent lid that leaves apart to light the light into it. With this cover, my fish is safe to live with my cat.
I have planted some plants in the tank and amazingly that they all survive with the light condition in the tank. In addition to bettas, I can drop cherry shrimp and small snails into it. I don’t think larger species can live in this small fish tank.
There are some people complaining that there is no place to add extra heaters, but that is not the case. I can attach a mini heater to the fish tank. Indeed it actually works much better than I expected without making my fish “boiled”.
7. Aqueon LED MiniBow Aquarium Starter Kits with LED Lighting
Buy it now
My children love fishes, so I gave them a glow fish as a Christmas present. At the same time, I also selected the future home for this new friend, that is Fluval Spec III Aquarium.
When I read the information online, I think it looks a bit small for my kids’ pets but in fact, it looks a bit bigger than the real size. The fish can swim freely without restricting the living space.
I have a few plants in the aquarium and luckily it can live well. The fish loves to sleep on the thick grass in the bottom of the tank. The glass surface is transparent and made of plastic. This makes it not as durable as acrylic one but in return, the small fish tank is very light and convenient for changing water.
Water filtration system works very well and minimizes noise.
If you often hear the noise coming from the filter, one way to improve is to fill the tank with water over the filter. For those who are new to fish farming and small aquatic animals, this small fish tank will be the best option for them.
8. Aqueon Princess Castle Aquarium Kit
Buy it now
My daughter like cute small fish tanks so last week I bought her an Aqueon Princess Castle Aquarium. Just like its name, it is an aquarium with a top of the pink castle shaped lid.
Nothing is better to decorate a girl’s room with a small fish tank like this.
In fact, the size of the aquarium is very small, only half-gallon. So I think this product is only suitable for betta or small tropical fish. In addition to the top of the castle, there is a feeding hole.
The fish owner can pass the hole to feed the fish, it is interesting, isn’t it?
Besides, the aquarium also offers some aquatic plants and decorative items. You can also decorate with your own map. My daughter does not like the accompanying products so she has decorated her aquarium according to her preference.
Good news for parents, this type of product is easy to clean, you don’t need to waste your time cleaning the aquarium. With the lid of the beautiful castle shape, cats cannot harm the fish in the tank.
9. biOrb CLASSIC 15 Aquarium with LED Light
Buy it now
My first impression of biOrb CLASSIC 15 Aquarium is the impressive transparent sphere shape.
Although I’m a bit disappointed because the aquarium is not accompanied by decorations like in the photos. But that doesn’t affect much. I can decorate the aquarium myself. I must say I am quite satisfied with my results now.
Also, the surface of the small fish tank is quite easy to clean the dirt. You just need to rub the sponge into the soil. I quite like ceramic media because it contains the nutrient-enriching bacteria in the water. The water filter is hidden so the aquarium always looks cleaner and easier to see the fish.
However, because the area of the aquarium is quite modest, I recommend that you do not put too many fish in the same tank, it will overload leading the fish to compete for living space.
10. Penn Plax Aquaponic Betta Fish Tank Promotes Healthy Environment for Plants and Fish
Buy it now
My original purpose when buying this aquarium was to decorate the new house. Actually, this aquarium made me impressed by its novelty.
It fits nicely as a home for my fish. At the same time, my family also needs some green trees to help ventilation.
The aquarium has two sizes including 1.4 gallons and 0.5 gallons. I bought 1.4 gallons because it was bigger so it was much more eye-catching when being decorated on the table top.
You can absolutely use mature plants to grow. However, it is important to consider which plants are beneficial for fish, which are harmful to the fish and which are suitable for growing in the home.
In addition to the high aesthetics, easy to decorate, the aquarium is also environmentally friendly. Fish will absorb most of the nutrients from the roots. However, you need to remember to change the water at least twice a week.
11. Umbra FishHotel Mini Aquarium
Buy it now
When I first heard the name of the fish tank, I felt this product was silly, a hotel for fish? How will the fish live with a hotel full of rooms?
In fact, I am the silly one. Umbra FishHotel Mini Aquarium is a solid block. It was still in the shape of a square fish tank but covered with the feeling that it was the walls and the glass leaving is the window.
There is no room, or it can be said that the hotel for fish has only one room. With a capacity of 1.8 gallons, my fish can happily live in it.
You can remove a few branches of decorative plants for the aquarium more vividly.
Although I’m a bit unfamiliar because the aquarium doesn’t show me the whole picture of the tank but it also gives me a new feeling instead of watching the fish in a boring way. My friends come to the house are attracted by the unique creativity rich in modernity in this vivarium.
This product calls up the excitement of finding unique small fish tanks in me. If you want to discover cool small fish tanks list, check the link below for more information.
12. Penn Plax Deluxe Triple Betta Bow Aquarium Tank
Buy it now
Another good product for you is the Penn Plax Deluxe Triple Betta Bow Aquarium Tank.
One difference between it and other aquariums is that there is a divided compartment that comes with the product. In fact, it’s not the attached part of the whole aquarium. You can optionally remove or reinstall.
The tank space may be a bit limited if you give 2 or 3 small fish to live in unless you are trying to breed.
At the bottom of the aquarium is lined with a water filtration system with fake plants. You will also be offered a pack of pro-V crystals that will absorb water-based sediments.
The aquarium is equipped with battery-powered lights, so there is no need to worry about aesthetics or inconvenience when moving the aquarium. Through the glass that surrounds the aquarium, the light becomes blue. The fake trees attached to the small fish tank when being lightened will be glowing, reflecting the light.
Nevertheless, the lighting system is battery powered, so it doesn’t seem to be very strong.
13. Back to the Roots Water Garden
Buy it now
This fish tank is likely to be an improved product of the Penn Plax Aquaponic Betta Fish Tank with a larger capacity and expanded plant area.
My fish loves this small fish tank. The design of the aquarium is beautiful and modern. I was given a package of seeds. And do you know what surprised me the most? The seed grew amazingly fast! In only 3 days, the grass has begun to thicken.
I do not encourage you to bring this aquarium to where light is too strong. Fish do not like this, on the other hand, the strong light promotes moss to grow faster. That means you will have to spend more time cleaning the aquarium.
The Roots Water Garden in particular and the aquarium plants, in general, make me appreciate the potential of this kind of small fish tank.
It is more decorative than conventional fish tanks, helping fish live longer thanks to organic nutrition and completely environmentally friendly.
How to Clean the Small Fish Tank
Here are a few quick and simple instructions for cleaning your aquarium:
1. Cleaning Fish Tank Filter
You only need to remove the filter (it will be easier if you remove the water in the aquarium first) and remove the sponge from the filter first.
Then clean the filter in cold water to remove any residue, use a long brush to clean the inside of the filter. The filter will clean the water in the tank longer.
2. Clean up bacteria in pebbles
Although the pebbles on the bottom of the aquarium seem to be clean, it may not be the case. Gravel is very easy to stain leftovers and fish waste. Leaving the gravel dirty for too long can cause mold to accumulate.
To clean gravel in the aquarium is very simple: remove the aquarium water until it is only about 1cm away from the gravel surface, then rub the dirt on the gravel with your hand.
3. Cleaning ornaments
If you are learning about fish tank cleaning tips, you probably know that chemicals should not be used to clean the aquarium.
However, it is sometimes safer for ornamental fish if the aquarium items are cleaned with a sanitizer, instead of letting it stay too long in the tank.
Take all the decorations out of the tank and soak them in a solution of one part bleach with nine parts of hot water and follow the instructions on the detergent cover. Do not forget to rinse the decorations with warm water before putting it back in the tank!
4. Cleaning glasses
Glass cleaning is probably one of the easiest tasks when cleaning the aquarium. To clean inside of the glass, you can use a magnet glass cleaner made from marine algae to clean the inside glass from the outside.
To clean the outside of the glass, you can use glass spray (such as a window cleaner) and wipe it with a dry cloth to keep the glass clean.
Above are the best products I want to send to you. Hopefully, these experiences will be helpful to you when making a decision to buy a fish tank.
However, to help you take better care of the fish, I will answer the question that most fish owners concerned, how to fish effectively.
