3 Things To Consider Before Getting A Tank
At first, you have to consider the space available and according to that, you have to decide which one is the better pick for you.
When you have limited space then having a 10 gallon fish tank could be the best option for you. If the tank is bigger than the room in proportion, then cramming a 20 gallon tank in a small room might make it look odd.
Besides, make sure to choose the space you are about to put the tank in that’s safe and free from clutter.
For limited space, you can consider a 10 gallon Aqueon fish tank to be one of the best matches for your interior.

Obviously a 20 gallon tank will cost you more than a 10 gallon tank would. However, the cost will also vary depending on the material used for the tank and also on the brand of the tank as well. Before getting a tank it’s really important to decide what amount you are willing to spend on the tank itself.
If you are willing to go a bit high on the budget you can get the luxury experience of fish keeping from SeaClear 20 gal Acrylic Aquarium Combo Set

With the glory of keeping an aquarium comes some regular maintenance work otherwise the whole system will fall apart. Normally a 10 gallon tank needs less effort than a 20 gallon tank.
Moreover, the smaller sized filters are easier to clean as well.
But the small fish aquariums need frequent water changes and water testing as well to keep the tank waste free.
However, normally the larger fish tanks have a more stable system due to their size. So it tends to provide a more stable condition for the fish. You see, the high volume of water lets the temperature and other parameters of it change very slowly.
As a result, the fish species have a better chance of surviving. Anyways, when it comes to cleaning, a 20 gallon tank can be a little fussy job. Though the advantage is, in a larger aquarium you can place more decorative objects and even more fish also.
What Kinds Of Fish Will Suit My Aquarium
Before choosing what fish species to buy you have to consider the capacity of your fish tank. Normally, a 20 gallon tank can accommodate more fish than the 10 gallon one.
Trying to get a large number of fish in a smaller tank is not a good idea. Because the small tank will not let the normal movement of the fish happen and the tank will get dirty very soon. And this will kill the fish eventually.
So the main purpose is to keep the tank as healthy and as clean as possible with the perfect number of fish.
Now, let’s check out what’s the ideal choice for both of the tanks–
For 10 Gallon Tanks
In a 10 gallon fish tank maximum 10 fish is ideal. But if the species grows larger, then limit the fish number to 7-8.
For a 10 gallon fish tank, you can choose from many species of fish including betta fish, neon tetras, zebra danios, guppies, mollies, dwarf gourami, goldfish, and so on.
Along with the fishes, you can decorate your fish tank with many decorative materials and some aquatic plants like water weeds, duckweeds, coontail, anubias etc.
Since 10 gallon tanks can get dirty more quickly than you have to change the filter cartridge or filter pads regularly. Make sure to clean and replace the filter cartridge every 4 weeks. However, if the ammonia and nitrate levels are high, change more often.
For 20 Gallon Tanks
For a 20 gallon fish tank there are more choices of fish species available. You can put around 19-2o fishes in the tank of the species including Betta fish, Guppy, Dwarf gourami, Neon tetra, Endler’s Livebearer, Harlequin Rasbora, Corydoras Catfish, Ghost shrimp, Platy, Bristlenose Pleco etc.
Besides, you can add some aquatic plants such as java moss, anubias, amazon sword, dwarf hairgrass, water wisteria, water sprite, hornwort, pennywort, pygmy chain sword, etc.
Frequently Asked Questions (FAQs)
Can I Use A 10-Gallon Filter In A 20-Gallon Tank?
No, it’s not a good idea to do that. Because a filter designed to work in a 10 gallon tank will not be able to clean the water properly if it’s used in a 20 gallon tank. As a result, the whole tank condition and fish health will deteriorate. So, it’s best to use the rated filter according to the tank size.
Is A 10 Gallon Fish Tank Too Small?
Normally when we compare the 10 gallon fish tank does seem like a smaller one but it’s still very suitable for having a few small fish in the homes. Just keep in mind that it will need more frequent water changes and more attention so that ammonia and nitrate levels don’t spike up.
What Happens If The Fish Tank Is Too Small?
If the fish tank is too small, the fish won’t be able to move freely and this will stress them out. Besides, in small tanks waste products like ammonia can accumulate and deteriorate the water quality. And this is harmful to the fish’s health and lifespan.
Comparing both 10 gallon and 20 gallon fish tanks is just about showing the pros and cons of each. In real terms, none of them is better than the other. Because at the end, it will all depend on what type and number of fish you choose and how you care and maintain the tank.
For a beginner 20 gallon tank can be best as it provides a more stable condition. But when you are low on budget, a 10 gallon fish tank would do just fine.
The main issue is as long as you keep changing the water and keep the tank clean on a regular basis, you can have any size of fish tank for yourself.
