Small Freshwater Fish
Fish For Small Aquariums. Yuji is a small fish tank, a hobby enjoyed by both beginners and experienced aquariums. After all, small aquariums are easy to install and convenient and have very little space requirements. However, one of the most common problems in these aquariums is determining what kind of fish will thrive in a space-constrained environment.
So, whether you’re setting up your own small aquarium or not, if you want to add more nano inhabitants to your tank, you need to know what type of freshwater species best suits your needs.
1. BetaBetta fish
Experience level: beginner to intermediate Maximum size: 3 inches Temperament: peaceful (under certain conditions) Water temperature: 75-86 ° F Water pH: 6.8-7.4 Aquarium robustness: Hardy Minimum tank size: 2 gallons Also known as siamese fighting fish, this beta fish is a tropical fish that only grows to 3 inches in length.
What is the easiest fish to keep? Fish For Small Aquariums
Beta up to 3 inches in size is one of the smallest freshwater fish and makes for convenient aquarium pets. It can be stored in a small bottom tank with at least 2 gallons of water. The male beta features vivid coloring and long flowing fins, and the female beta is less colored and has relatively short pins. Their beautiful appearance gives them an amazing aesthetic appeal. Because they have a solid arrangement, they endure poor water quality, change the water temperature, and have no difficulty in narrowing the space.
However, a regular exchange of water is required. The bettas are essentially peaceful species, but because of their tendency to fight each other, do not put two males in the same aquarium. On the other hand, multiple female betas have no difficulty living together and can be stored in the same tank as one male beta.
2. Heavenly Pearl Danios Heavenly Pearl Danios
Experience level: beginner Maximum size: 1 inch Temperament: peaceful school fish Water temperature: 73-79 ° F Water pH: 6.5-7.5 Aquarium robustness: Hardy Minimum tank size: 10 gallons If you are looking for a small freshwater fish that can increase the aesthetic value of your aquarium, check out the Sky Pearl Danio.
It is a freshwater fish with a beautiful appearance that comes with sky pearls and is available in various colors. They are popular aquarium fish due to their size, peaceful temperament, and coarse tendency. The distinctive features between fish species and females are abundant. But the most interesting thing is in appearance because the male Danio is smaller and more colorful than the female.
Adults are small and the maximum length is 1 inch. Because of its small size, it can be stored in a 10-gallon tank that carries the celestial pearl and must be planted to imitate its natural habitat. For best results with this fish, keep Danio in groups of 5 or 6 or more and see if there are more women than men. It is an omnivorous animal that carries the pearl of the sky. They eat everything from algae, plant and saltwater prawns to flakes, pellets, and live bugs.
3. Neon TetraNeon tetra
Experience level: Intermediate Maximum size: 2.5 inches Temperament: peaceful Water temperature: 70-81 ° F Water pH: 6.0-7.0 Aquarium robustness: Hardy Minimum tank size: 10 gallons The neon tetra is a freshwater tropical fish and can reach up to 2.5 inches long. However, the average length of the neon tetra is 1.5 inches.
For fish growing up to 1.5-2.5 inches, neon tetra can be stored in a 10-gallon tank. However, when school sizes are small, Tetra is prone to stress, so you need to secure at least 15-20 tetras and store them in a 20-gallon tank. When designing aquatic homes, add a lot of low light hiding to the tank. These creatures can live more comfortably in a dark environment, and overall it is better to provide a place to hide and rest.
Neon Tetra is a peaceful and enjoyable fish that works great in community tanks because the tank mate is small and has the same temperament. They are also very popular among beginner lovers because they are very low maintenance pets. Neon Tetra is omnivorous, so you can enjoy almost any food.
Experience level: beginner Maximum size: 2.5 inches Temperament: peaceful Water temperature: 66-84 ° F Water pH: 7.0-8.0 Aquarium robustness: very rigid Minimum tank size: 10 gallons There are many reasons why goofy is one of the most popular fish species in the fishing world.
Best of all, they are very hardy fish that require minimal care from start to finish. Other reasons include a convenient size and an incredibly impressive appearance and come in unlimited color combinations. Male guppies can grow up to 2 inches in length, but male guppies are relatively larger and tend to grow to 2.5 inches long.
This cute little creature can grow to 2 to 2.5 inches in length, so we recommend an aquarium with a capacity of at least 10 gallons. No fish training, but guppies should be kept in groups of at least 6 people. However, when grouping goofy, keep the ratio of men and women to 1: 2 so that they do not fight in the tank.
If you plan to give them tank mates outside your own species, look for small, medium-sized fish that are peaceful and not aggressive (Cory Dora, Bellflower, etc.). Guppy is an omnivorous animal and willing to eat in-flight meals, freeze-dried foods, and flake-based aquarium foods.
5. Sparkling Gourami
Flashing gourami Experience level: beginner Maximum size: 1.6 inches Temperament: relatively peaceful Water temperature: 71.5-80.5 ° F Water pH: 6.0-8.0 Aquarium robustness: Hardy Minimum tank size: 15 gallons Shiny Gourami is a small freshwater aquarium fish up to 1.6 inches long and can adapt to a variety of environments including harsh water conditions.
Ultra-compact shiny gourami is a great option for those looking for small freshwater fish. Shiny Gourami has pattern pins that make up a significant part of the elongated torso. They also feature small pelvic fins, combined anal fins, dorsal fins, and striking blue eyes surrounded by thin red lines. It is very easy to distinguish the shiny gourami from other small fish in a rather unique shape.
In addition to the incredibly convenient size, the shiny Gourami is a peaceful creature, which should be kept in groups of at least 5-6, and 1 male is recommended for every 3-4 women. In addition, storage in tanks with other fish species is no problem. However, for everything to work out well, the tank mate must have a calm temperament and be roughly the same size. Examples of good Kurami tank mates are Tetra, Corridor, Las Boras, and Neon Rainbow.

It resembles one of nature’s most diligent and important animals, bees.
Adult bee ferns can reach up to 1.7 inches in length and must be stored in tanks with a capacity of at least 10 gallons. Since ferns are group fish, they should be kept in groups of at least 6-7 of the same species. The bumblebee fern is a very active swimmer, and the tank must have enough space to swim.
They also like to hide, so it’s a good idea to provide sand imprints, living plants, river rocks, and driftwood.
Bumblebee fern is a hardy fish species but is often not recommended for beginner aquarists because of its demanding nature.
7. Dwarf Buffer
Dwarf puffer Experience level: Intermediate Maximum size: 1 inch Temperament: Territory / Attack Water temperature: 72-79 ° F Water pH: 6.5-7.5 Aquarium robustness: not strong, very salt resistant Minimum tank size: 10 gallons The dwarf respirator is a relatively new fish in the aquarium hobby scene.
They are freshwater fish species that thrive in a more comfortable environment, so they should never be placed in a brackish or saltwater tank. The adult dwarf respirator can grow up to 1 inch long, making it one of the smallest aquarium fish in the world. Very small in size means you don’t need a large tank, but you still need to provide a tank with a capacity of at least 10 gallons.
When installing a tank with a group of dwarf respirators, the ideal tank setting is 10 gallons for the first respirator and 5 gallons for each additional respirator. The dwarf pufferfish is a territorial fish species that require a lot of personal space despite its small size. Having enough space in the tank will help lower your aggression. Also, creating more hiding places can lower your stress level, so it’s a good idea to add a lot of plants and rocks to the tank.
8. Ember TetraEmber Tetra

This fish species is easily discernable due to its flaming hot appearance.
Ember tetras are very small and can grow up to 1 inch in adults. However, the standard size of ember tetras is about 0.8 inches. Ember Tetra is smaller than most fish species but is an active swimmer who likes to play in the middle of the tank, hiding in plants and rocks. So, if you want them to be happy, at least you should keep them in a 10-gallon tank with lots of lairs.
Ember tetras are relatively hard fish species that can adapt to different water hardness and pH levels. However, if the water quality and fluctuations are severe, it is affected. When it comes to diet, the barren tetra is an omnivorous fish species that eat flakes, pellets, and live food, among other things. Stay healthy by giving them a varied diet.

Salt and pepper catfish are strong and can adapt to different water quality conditions, but are considered delicate species due to their extremely warm temperatures and their vulnerability to poor water quality.
