The powder blue gourami is a very popular variant of the dwarf gourami due to its lively color and small size. These fish are relatively robust and perfect for beginners and experienced hobbyists as they do not take up much space in the aquarium and are easy to care for. While it is a simple variety, it is still important to know how to give your powder blue gourami the best possible care so that it can lead a happy and healthy life!
Read on to find out everything you need to know about powder blue gourami and how to prep your freshwater tank before you get one!
Trichogaster lalia (formerly known as Colisa lalia) is commonly known as dwarf gourami; These fish are also known as labyrinth fish because their lung-like labyrinth organ allows them to breathe air from the surface of the water, similar to Bettas.
The powder blue gourami is a selectively bred modification of Trichogaster lalia as a result of the aquarium hobby. These fish are named for their firm, light blue bodies; However, due to the intensive breeding in the aquarium trade, most fish have different colors or patterns on their bodies and are not really firm.
While the powder blue variant does not exist in the wild, dwarf gouramis come from Asia. They are primarily found in slow-flowing waters with thick vegetation, such as ponds, streams, and lakes throughout Pakistan, India, and Bangladesh.
Because of their popularity and selectively bred color variations, most fish are aquacultured and rarely harvested in the wild. As a result of this popularity in the home aquarium, populations have also been introduced through release into external ecosystems such as North America.
Dwarf gouramis are other Trichogaster sp. Very similar in full size, only smaller. They are usually most easily recognized by their long, thread-like ventral fins, which sit under the gills and help the fish become more aware of their surroundings and locate food.
Otherwise, powder blue dwarf gouramis can be recognized by their steel blue color, their deep bodies and their broad fins. While exemplary powder blue gouramis are monochromatic, selective breeding has resulted in other colors and patterns appearing in these fish. It is not uncommon to see a powder blue dwarf gourami with some degree of purple streaking on its body.
How big do blue dwarf gouramis get?
How big do dwarf gouramis actually get? On average, these fish reach three to four inches, with the majority remaining on the lower end of this range. These fish stay small and with extreme care can live up to 5 years!

How can you tell if a gourami is male or female?
In general, women are much smaller than men and not as colorful or ornate. Most males also develop elongated dorsal and anal fins in adulthood, which makes it relatively easy to get a breeding pair of powder blue gouramis.
Requirements for a powder blue gourami tank
Powder blue gouramis are usually a perfect peaceful fish for a community tank setup. These fish are a popular centerpiece for 10 gallon (37.9 L) nano tank setups because they are different in shape and color from most other small tropical species.
Dwarf gouramis can be shy fish and actually be affected by conditions outside the tank such as loud noises or flashing lights. For this reason, it is best to plan the placement of the tank as far as possible from possible stresses like these. In addition, these fish will love lots of plants and caves to mimic their natural environment. Dark substrates also help bring out the best possible colors in your fish.
Otherwise, these fish need a tropical water temperature between 22.2 and 27.8 ° C and a pH between 6.0 and 8.0. These fish come from slow flowing waters and are not the best swimmers with higher flow. You will appreciate the plant cover on the surface of the water in the form of duckweed or some other floating species for added protection. Most other freshwater plant species can also be used to cover the foreground, midground and background of the aquarium.
Due to intensive breeding, these fish have suffered genetically and are more prone to freshwater fish diseases such as ego, leeches, and other parasites.
Powder blue Gourami tank mates
While powder blue gouramis are a good fish for beginners, they must be considered when choosing tank mates.
Because these gouramis are shy, they shouldn’t be kept with more active, aggressive species of fish that tend to nibble on fins, such as danios and guppies. Some hobbyists have been fortunate to have both danios and guppies along with dwarf gouramis, but it is very likely that their constant water surface activity is putting your fish under strain.
Instead, powder blue gouramis are best for slow, smaller fish that are getting the most out of their colors. Some potential powder blue gourami tankmates might be angelfish, rasboras, and some tetra species. Gouramis are particularly suitable for basic inhabitants such as loaches, corydoras and otocinclus, who stay outside the middle and upper water column.
If you don’t want extra fish with your dwarf gouramis, a selection of aquatic plants will look just as good and natural!
How many gouramis should be kept together?
Dwarf gouramis are by nature loose school fish, but most hobbyists like to keep them alone or in larger groups. Even then, many hobbyists have had a number of results from keeping groups of gourami instead of keeping them alone.
Some hobbyists have compared dwarf gouramis to betta for aggression. Different gourami species are sometimes just as aggressive and territorial to one another as they are to the other community fish in the aquarium. Most hobbyists also have trouble preventing men from molesting women during the spawning season, even when the ratio is reasonable.
Others had no problem keeping a small or large mix of gourami in the tank. It should be noted that these fish tend to do better in larger tanks if they are planning to run a school.
Do gouramis like to have two?
Many aquarists keep these fish to themselves. It is believed that the males do better on their own, while the females appreciate company. If you are buying an already mated pair, there should be little or no problems. However, if you are planning to buy an independent man and woman, there is a good chance the man will become territorial and aggressive. In this case, it may be better to buy more women than men.
Powder blue gourami behavior
Aside from their aggression, powder blue gouramis are cautiously considered community fish. These fish like to stay in the upper and middle columns of water and are not overly active swimmers.
You will chase other fish and nibble on fins during spawning season if you have a particularly aggressive male.
Powder blue gourami diet
Powder blue gouramis are omnivores and easy to feed in the aquarium. In order for them to show their best colors, they must be fed a plant-based and animal diet once or twice a day.
Dwarf gouramis fish are best for high-protein fish flakes or pellets. These fish tend to stay at the top of the tank, so foods that float for a few seconds may be easier for your fish to eat. Otherwise, they may be fed various live, frozen, and freeze-dried foods such as bloodworm, brine shrimp, and mosquito larvae.
Since they are omnivores, they will also appreciate blanched vegetables like zucchini and lettuce as well as seaweed pellets / waffles every now and then. A healthy fish with a varied diet is sure to show its best possible color!
Blue gourami breeding powder
Dwarf gouramis are fascinating and relatively easy to breed in the aquarium hobby. Like Betta fish, powder blues form bubble nests to reproduce and spawn. Due to the aggression of the male, it is highly recommended to set up a separate breeding tank.
This breeding tank should be identical to the exhibition aquarium in terms of water quality and temperature. Plants are valued as males tend to use them to build the nest. The water flow should be minimal so as not to disturb the nest once the male has built it. A substrate is not needed, although either gravel or sand will work. If your couple shows no signs of spawning, try a series of water changes as you gradually increase the water temperature.
As soon as the conditions are right, the male begins to build the nest on the surface of the water and becomes very aggressive towards the female gourami. The fish interlock and breed under the bubbles so that the fertilized eggs can swim to the surface under the protection of the nest. The male catches anyone who cannot get up and places them in the nest.
After all eggs have been fertilized, the female should be brought back to the main display as the male will take care of the nest and can become aggressive. The eggs should hatch within 36 hours depending on the water temperature and the nest will break apart once they have hatched successfully. The male can then also be returned to the main display tank or remain with the brood for a few days.
The roasts are very small and must be fed with small foods such as baby brine shrimp. They can eventually be moved to larger foods as they grow. In some cases it is necessary to set up multiple storage containers as the brood tends to grow at different rates, which can lead to bullying. Remember that these fish can have up to 700 eggs at a time!
The powder blue is a very popular color variant of dwarf gourami species. Relatively easy to care for, they’re a popular choice for beginners looking for a colorful and hardy fish. However, individuals can be aggressive at times, which can limit the other types of fish you can get for your aquarium, including other gouramis.
When keeping a pair of these fish, watch for bubble nests on the surface of the water and changes in the man’s temperament. Have several tanks ready, as the brood can grow at different rates!
