Fish Species You Can Keep in 20-Gallon Aquarium
After you have chosen the tank kit, you will have to decide which fish you will put in it. Or maybe you have made that choice prior to buying the tank and you adjusted the tank to the fish.
Either way, choosing the right fish for the tank is an important part of creating a good tank environment, and you will also have to consider which fish are compatible with each other.
The guppy fish is one of the most common choices when it comes to smaller tanks. There are plenty of reasons as to why you would want to own guppy fish in your tank.
Firstly, they are very peaceful and will do well in a tank full of other fish. They are not too demanding and very easy to care for. Keep 5 or more of them together to see the best results.
The betta fish is a very popular choice for smaller tanks. This is due to the fact that it is very unique both in temperament and in appearance.
As it is quite an aggressive and territorial fish, it is better that it is kept alone, or at least do not keep two male betta fish together, as they will fight constantly. Other than that, its appearance is very appealing and one of the reasons for keeping the betta fish.
Sparkling gouramis are great little fish for a smaller fish tank. That is due to the fact that they are friendly and non-aggressive to other fish and they will not require too much attention and care from your part.
Some other good fish for a 20-gallon tank are neon tetras, pygmy corydoras, platy fish, balloon molly fish, danios and harlequin rasboras.
Should You Add Live Plants in a 20-Gallon Aquarium?
In short, the answer is probably yes, because live plants will create conditions that will resemble the natural habitat conditions, but will also help keep the water clean and will produce oxygen that will keep the fish healthier.
If you are a beginner, it may be better to stick with the plastic plants at first, though. This is due to the fact that live plants can be quite sensitive at the beginning, and will not grow under the right conditions.
But if you want to start with live plants right from the start, please read my absolute beginner’s guide to planted aquarium, which will help you understand how to take care of them.
But live plants are usually better for a 20-gallon tank. Make sure that you clean and rinse them properly prior to putting them into the tank, to get rid of the snails and other bacteria that might be on the plants.
How to Maintain a 20-Gallon Aquarium?
Ideally, you will want to perform maintenance checks every couple of days, if not every day. This will ensure that the conditions of the water are right for the fish and that they are happy and healthy.
When performing these checks, you will want to measure the temperature of the water with a thermometer to make sure that it is in the right zone for the fish in the tank. If you have tropical fish, this is even more important.
Secondly, you will want to clean the tank as much as possible and measure the alkalinity of the water. In addition, you should try to cycle the water at least once a week. This will ensure that the water is clean. To perform a water cycle, change about 30% of the water from your tank with fresh water (dechlorinated with a water conditioner) once a week.
Also remember to feed the fish high-quality foods, but do not overfeed them, as that might cause obesity and an increase in snail population and food leftovers.
Buying a 20-gallon tank is one of the most popular choices for new aspiring tank owners. Fish tank kits make your choice much easier and save you the hassle of having to look for tools and features that are already included in the kit.
All in all, fish tank kits are made with the beginners in mind. Consider these tank kits on this list if you do not know where to start.
