How Many Dwarf Gourami in a 10 Gallon Tank: The Ultimate Aquarium Care Guide

A 10-gallon tank can house up to three dwarf gouramis. In addition, keep an eye on the size of their tanks, as dwarf gourami can reach up to three inches in length. If you have more than three dwarf gouramis, consider adding a larger tank or purchasing different types of fish to share the space.

How Many Gouramis Should Be Kept Together?

Four or more dwarf gouramis should be kept together. However, the number of gouramis you should keep together in a tank is up to you and depends on the size of the tank, type and age of the fish, and other pets or creatures in the home. Generally, it’s best to have three to four small gourami species instead of one large specimen.

Large groups can compete for food and territory, causing stress and possibly even aggression among members. Additionally, dwarf gourami is sensitive fish and can be harmed if they’re kept in an overcrowded tank.

Growing Multiple Gouramis in a 10-Gallon Tank

There is no right way to grow multiple gouramis in a single fish tank. Some people use a sizeable aquascaping container, while others keep the fish separately in smaller tanks. It’s also possible to purchase dwarf gourami breeding pairs or trios to keep multiple gouramis in a single tank.

So, there’s no wrong way to go, as long as the tank is large enough and the fish are adequately spaced out.

The Male-to-Female Gourami Ratio in a 10-Gallon Tank

The ratio will already be established if you purchased a breeding pair or trio. On the other hand, if you’re only keeping one or two dwarf gouramis in your tank, there’s no need for concern, and any additional males can be eliminated without harm. In addition, dwarf gourami is not particularly territorial and usually tolerates other fish in their tank.

In short, there is no definitive answer to how many dwarf gouramis should be kept together in a 10-gallon tank. Instead, it depends on factors such as the size and type of tank, the age and species of gourami being kept, and any other pets or creatures in the home.

Do Gouramis Need to Be in Pairs?

No, gouramis can be kept singly or in small groups. However, many prefer to keep at least one dwarf gourami together to form a social partnership. This helps the fish communicate and interact better and provides companionship during stress or boredom.

Additionally, dwarf gourami is a very active and curious fish, so having one or two buddies around can make a big difference in their overall enjoyment of captivity.

Will Two Male Gouramis Fight?

Male dwarf gourami is not naturally territorial, but they may start to compete for food and territory if kept in close quarters with another male. If this happens, removing one of the males from the tank is best and allows them to resolve their differences singly.

In addition, dwarf gourami is generally peaceful fish, so there is rarely any need to worry about them attacking each other.

Can You Keep a Single Gourami in a 10-Gallon Tank?

Yes, you can keep single dwarf gourami in a 10-gallon tank, provided they are of the same age and size. However, it is generally better to have at least one fish in the tank to interact socially and cooperate with the inhabitants.

Additionally, having a friend can make the fish feel more secure and less likely to get lonely in their small home. So, if you’re considering adding dwarf gourami to your tank, keeping at least one other fish is recommended.

Adding New Gouramis to a 10-Gallon Tank

Typically, it is best to slowly add new gouramis to a fish tank over several days so that they have time to get used to their new surroundings. Simply moving them into their new home unannounced can cause them anxiety and stress, negatively affecting their overall well-being.

Next, it’s a good idea to provide them with plenty of food and water to settle in. Once they feel more comfortable, you can start introducing other fish into the tank, one at a time.

Finally, always keep an eye on the gourami to ensure they are not getting bullied or attacked by their tank-mates. If necessary, you can remove any fish that is making them feel uncomfortable and replace them with a more compatible individual.

Do Gouramis Kill Other Fish?

Gouramis are generally peaceful fish and will usually avoid attacking other tank-mates. However, they may resort to biting to defend themselves if they feel threatened or cornered. In rare cases, gouramis have been known to kill other fish when their tanks become overcrowded. So, it is essential to keep an eye on the population size and ensure enough room for all inhabitants.

Additionally, ensure that your gourami has the proper environment and diet for their size if you are concerned about killing other fish. For example, small gourami generally requires less food than a large one.

Suitable Habitat and Tank Conditions in a 10-Gallon Tank

Gouramis typically enjoy a well-lit, warm environment with plenty of swimming space and are recommended to have a filtered aquarium and water at room temperature.

Tank Setup

A 10-gallon tank is optimal for gourami, but they will also do well in larger tanks. Ensure to provide plenty of hiding spots and other resources to stimulate their hunting behavior. Additionally, add some aquatic plants or rocks to the bottom of the tank so that they can bury themselves in the nutrient-rich substrate.

Tank Mates

Gouramis are generally peaceful fish but do well with other similar-sized aquarium residents. Avoid adding aggressive fish to your gourami’s tank, as this can lead to tension and possible aggression. Instead, select a compatible community of fish such as neon tetra, cardinal tetra, mollies, and zebra danios that will all enjoy the shared environment.


Gouramis are generally easy to care for and require minimal supplementation. They should be kept clean by weekly water changes, adding fresh substrate and aquatic plants (if desired), and removing unwanted fish ornaments.


Gouramis feed primarily on aquatic insects, so make sure to provide them with a quality diet that includes plenty of insect food. Feed your gourami small meals several times daily and watch for any changes in their activity or temperament.


Although not generally recommended, breeding gouramis is possible in a well-maintained tank. However, be aware that they can become territorial and aggressive during spawning season. In addition, be sure to provide a suitable breeding tank with plenty of hiding spots, plants, and other resources.
