Introduction to Powder Blue gourami
Powder blue gourami fish is a coloured variant of Dwarf gourami. Therefore we can call as Blue dwarf gourami as well. This fish has a nice light blue coloured body.
Some fish have a completely blue-coloured body, and some fish may have patterns on the body.
Breeders developed this powder blue gourami to create beautiful fish for aquariums. It’s a shy fish. As they are peaceful can keep at the community tank with the right tankmates.
A special characteristic feature regarding this fish is the presence of an organ call labyrinth.
Because of the labyrinth, fish can facilitate breathing under the lower oxygen levels by taking the gulp of oxygen directly from air by coming to the surface.
These fish prefer shady environments very much.
So you can provide dense aquarium planting. Aquarists say powder blue gouramis are well suites for a beginner fishkeeper.
It’s a great addition to the tropical fish water tanks. Under this article will give you a full care guide about powder blue gourami keeping. Continue reading!

Origin and Distribution
Powder blue guramis is a developed variety from dwarf gourami under captive breeding. Therefore dwarf gourami is from South East Asia, including Pakistan, Bangladesh, Malaysia, Korea, Japan, and china countries.
This can especially be found on slow moving water streams such as irrigational streams, paddy fields, and other agricultural irrigations, creeks, etc.
It is also distributed among the USA, Colombia as well.
Due to a misunderstanding, earlier aquarists thought blue gouramis are originated from Nepal and Myanmar. But later, it was corrected. Another common name used to identify this fish is coral blue dwarf gourami.
Powder Blue Dwarf Gourami Appearance
By the name, it gives clues about the body colour. It is a light blue colour fish. I told you earlier some have markings on the body. They are light orange vertical stripes similar to the neon dwarf gourami.
Typically fish have a compressed which is oval. When looking at the fins, they are large and rounded. Except for the ventral fins, it is pointed and contains very sensitive cells.
The most important characteristic feature is the presence of a labyrinth organ. It is located in the head just behind the eyes. So fish is well adapted to the low oxygenated environment.
Males have brighter colours and a small abdomen compare to females.
You also can see sensory appendages just similar to barbel in pond loaches as well.
How big do powder blue dwarf gouramis get?
It can grow up to about 2-4 inches. So average size is about 3.5 inches( 8.7cm) in captivity.
This depends on how you care for the fish; quality feeding enrich with a high protein diet is important.
Note: Females are smaller than males; they grow up to about 2.4 inches.
How long do powder blue gouramis live?
Powder blue gourami has a lifespan of 4 to 7 years. Therefore the average lifespan is about 5years. If your care is good, it will live up to about 7 years.
Aquarium care and tank setup
Giving good care can prevent lots of diseases and uncomfortable factors. Most of the fishkeepers get confused, thinking fish can live well in the low oxygenated tank.
Yes, it is true, but similar to other fish changing water is needed.
Otherwise toxic chemicals such as ammonia, nitrate harm the fish and cause stress. So it is recommended to change 20-25% of water weekly.
When it comes to the aquarium, set up fish more likely to have a shady environment. So selecting a darker substrate is a good option. You can use dark gravel or soft sand.
When decorating the tank, use more live aquarium plants because it’s a shy fish. Experts say it is better to dense aquarium tanks with 50% of aquarium plants.
In addition to that, driftwood, bogwood, airstones, rock caves are okay to go with.
Since they do not need much lighting can use floating plants like hornwort at the surface to filter out the light.
These fish naturally live in slow moving water, making sure the tank has a moderate water current. So filtration operating at a moderate level will okay.
Note: These powder blue gouramis are nest builders, not breeds by laying eggs called egg scatters or egg depositors. So live aquarium plants play an important role in breeding and provide lots of hiding places.
Optimum powder blue gourami temperature is between 72-82 Deg F(22.2-27.8 Deg C). The breeding temperature is slightly higher than the normal temperature. It is around 84 F.
Sudden changes in water temperature can stress the blue gouramis. Be aware of that!
The optimum pH level is around 6-7. Therefore slightly acidic water is preferred. Water hardness should be between 5-18 dGH.
Dissolved Oxygen level
These fish are well adapted to the low oxygen environment because they can take a gulp of oxygen from the surface. So oxygen is directly absorbed into the blood.
The main reason is these fish can’t get enough O2 only with the gills. You can keep air stones and aerators to increase the oxygen level within the tank.
The minimum tank size for blue dwarf gourami is between 15-20 gallons. If you have an idea to add more gourami to the same tank, each additional fish need extra 5-10 gallons of water.
Gender identification of blue dwarf gourami is important when it comes to breeding. There we need to select the best breeding pair.
We can differentiate by looking at the size. Males are smaller than powder blue gourami females. Also, females have short curved dorsal fin, whereas males dorsal fin is pointed.
Another character is the belly or abdomen. Females have a large abdomen compare to males, and it is rounded.
When it comes to body colour, males are with brighter colours, and faded colours are found at the females.
Breeding powder gourami is easy. You can give a separate breeder tank for breeding.
Slightly increasing the water temperature induces the breeding process. Another important practice is keeping the water level low. You can keep the water level at 6-8 inches.
The main reason for this is the Blue dwarf gourami are nest builders.
It creates a bubble nest on the water surface. It is made up of plant debris and saliva. Having a dense aquarium planting facilitates the nest-building process.
You can use plants such as milfoil, hornwort, ricca, etc.
Before adding male fish, it is advisable to add one or more females. You also need to condition the females before breeding with a quality diet.
You can add males, and it will start to chase the females in the morning or evening. She will produce about 5 dozen eggs at the beginning.
Note: Male, after chasing, get the female to attract to the nest.
Aquarists say males will fertilize the eggs as soon as it releases from the female body. Then pair spawn until produces about 300-800 eggs.
Male powder dwarf gourami also collects any eggs that are not present within the nest and adds them to the nest.
Now it is better to remove the female gourami. Otherwise, the male can become intolerant.
It needs to keep male fish until eggs get to hatch. Eggs will hatch around 2-3 days. Now you can remove the male fish as well. Otherwise, accidentally can eat by the adult male blue dwarf gourami.
Once little babies start swimming around 4-5 days, you can feed them with microorganisms, infusoria, and other fry food.
Powder Blue Gourami Tankmates
As they are peaceful can keep in the community tank. But never keep two males in the same tank. They can be territorial and possibility of fighting each other.
Best tankmates are as follows,
- Harlequin Rasbora
- Dwarf rasbora
- some of the other tetras
- Cory Dora catfish, Rainbowfish
- gold barb
- Cherry barb etc.
But never keep with fin nippers such as Kuhli loach, Tiger barb, Bloodfin tetra, Bettas, Guppies, Clown barbs, Angelfish etc. So go with nonfin nipping bottom dwellers. I hope you get the point!
What does Powder blue gourami eat?
They can feed a wide variety of food because blue dwarf gouramis are omnivores. Giving a good quality protein rich diet can help to condition the fish at breeding.
You can give live frozen and freeze dried food, including Daphnia, Blackworms, white worms, mosquito larvae, Mysis shrimp, Brine shrimp, Bloodworms, omega/freshwater flakes, Algae wafers, etc.
I am feeding blanched vegetables such as lettuce, spinach, cabbage help to maintain body colouration as well.
Experts in this hobby say feeding twice a day is effective.
- Diet – Omnivore
- Feeding- Twice a day
As I told earlier shows peaceful behaviour, so easily kept in the community tank.
How many Gourami should be kept together?
They are not shoaling fish—most of the time, Powder blue gourami sold as pairs. Never keep two males together. It shows aggressive behaviour.
Two females, along with one male, are okay to go with.
But be sure not to overcrowd. If it is, male fish can kill even non-gourami tankmates as well. If you observe a male, always bullying a female and chasing it can cause her stressed.
Therefore the high risk of getting various diseases. ( Be aware!).
Male can even live alone without a female fish, but females need one or more companions to live.
Common Possible diseases
These fish are hardy but can susceptible to various diseases if the water conditions are poor.
Even if not getting enough protein rich balanced diet, chances of getting diseases are higher. Let’s see!
Another major way of introducing pathogens such as viruses, bacteria, protozoans, and fungi is through aquarium decorations like driftwood, aquarium plants, and new fish, etc.
Before adding to the home tank, quarantine all the above mention things.
Major disease associated with Powder blue gourami is the Irido virus, a viral disease caused by a virus belonging to the Iridoviridae family.
It is a double stranded DNA containing the virus. According to aquarists, the main pathogen causing this virus is the Megalocytivirus. It affects mainly fish kidneys and spleen.
- Degrade of colour
- White pieces
- Not eating (reduced appetite)
- Lethargic behaviour
- Swelling of the spleen is some of them.
You can’t use antibiotics to cure as it is a virus disease—the best way to treat the disease by vaccination.
Note: Within the laboratory, the disease can diagonalize using a PCR Test.
These Blue gourami are a beautiful fantastic addition to the home aquaria. Even a beginner fishkeeper can easily care for.
Breeding also not that much difficult. I hope this article will help you get a clear idea about Powder Blue gourami keeping.
