The Powder Blue Dwarf Gourami is an attractive color-morph of the Dwarf GouramiTrichogaster lalius. It is one of the more "solid" colored varieties. It has a beautiful iridescent "powdery" blue coloring overall with very diminished vertical red striping. It was developed by breeders selectively pairing specimens for the desirable blue coloration and strengthening it over several generations. This resulting gorgeous fish makes an outstanding show specimen for the aquarium.
This variety is sometimes called by other common names like Coral Blue Dwarf Gourami and Blue Dwarf Gourami. Other than its coloration however, this variety is the same in in all other manners as its predecessors. These fish stay fairly small with the males reaching only about 3 inches (7.5 cm) in length. The females are a bit smaller at around 2 1/3 inches (6 cm).
This fish is a Labyrinth fish, so are distinguished from other types of fish by their ability to breathe atmospheric oxygen. They have gills like all fish, but they also have an additional respiratory organ called the "labyrinth organ". This is an adaptation that gives these types of fish the ability to breath oxygen by gulping air at the surface of the water. It has been found that the size of this organ is individual to each fish, depending on the environment it is adapted to. Labyrinth fish that are adapted to oxygen depleted or highly polluted waters will have a more extensive organ than those living in good quality water that is plentiful and well oxygenated.
Another labyrinth fish characteristic is that of being a bubble nest builder. In an aquarium with an active male, you can see a cluster of bubbles on the top of the water. Once the female lays the eggs, the male will pick them up in his mouth and put them in his bubble nest and will continue to guard the eggs until they hatch.
This fish is quite hardy and makes an excellent choice for the beginning aquarist as long as it's housed in a properly set up tank with regular maintenance. It is undemanding and fairly easy to breed as well. With its small size a single fish could be kept in a smaller aquarium of at least 5 gallons, but a 10 gallon tank will suit it much better. The tank needs lots of plant cover for nest building, but also to provide plenty of places to hide. A larger aquarium allows for a better planted arrangement and the water will be more stable, and there will be room for some companions as well.
These fish are usually peaceful and will be fine in a community tank. But they are little timid, especially if housed with fish that pester them. Fish that are very active, large or aggressive will cause them to withdraw. On the other hand fish that are gaudily colored, like guppies and bettas, as well as other dwarf gouramis, will bring out a territorial aggression in them. The best tankmates are other species of small, peaceful fish.
The Powder Blue Dwarf Gourami is just one of a number of beautiful varieties that have been developed from the Dwarf Gourami. Some of the other popular varieties include the Neon Blue Dwarf Gourami, also known as the Rainbow Gourami, and the Flame Dwarf Gourami, also known as the Fire Red or "Blood" Red Dwarf Gourami.
The Dwarf Gourami Trichogaster lalius (previously known as Colisa lalia) was described by Hamilton in 1822. It was originally found in South Asia from Pakistan, India, and Bangladesh. At one time it was believed to occur in Nepal and Myanmar as well, but that is now thought to be as a result of misidentification. However it has now been widely distributed outside of its native range with feral populations found in Singapore, the United States, and in Colombia.
The Powder Blue Dwarf Gourami is a captive bred color morph developed from the Dwarf Gourami. This variety was developed by breeders over several generations, by selectively pairing specimens for the desirable blue coloration. Other common names they are known by include Coral Blue Dwarf Gourami and Blue Dwarf Gourami.
In nature the Dwarf Gouramis are found in slow-moving streams, rivulets, rice fields, irrigation channels and other agricultural lands. They primarily occur in areas with thick vegetation. They are omnivorous and feed on small invertebrates, algae, and other aufwuchs.
Scientific Name: Trichogaster lalius
Social Grouping: Groups - In nature this species lives communally with other peaceful species.
IUCN Red List: NE - Not Evaluated or not listed - There are no wild populations of this color morph.
The Dwarf Gouramis have a somewhat compressed, oval shaped body and the fins are rounded and relatively large. The ventral fins are threadlike and carry touch-sensitive cells that are extremely perceptive. They have a labyrinth organ, a part of the fish which allows it to absorb atmospheric oxygen directly into the bloodstream. They have an average lifespan of 4 years, but can live up to 7 years with proper care.
The Powder Blue Dwarf Gourami is a captive bred color variety developed from the Dwarf Gourami. The males will normally reach about 3 inches (7.5 cm) in length, with the females being slightly smaller at around 2 1/3 inches (6 cm). Their coloring is very pretty 'powdery' almost iridescent blue overall with very subdued vertical red striping on the body and fins.
Size of fish - inches: 3.5 inches (8.79 cm) - In the aquarium these fish are normally smaller, with the males reaching about 3" (7.5 cm) and females about 2.4" (6 cm).
Lifespan: 4 years - The average lifespan is 4 years, but with proper care they could live as much as 7 years.
Fish Keeping Difficulty
This is a hardy fish and makes a good choice for the beginner. They are fairly undemanding as long the tank is properly set-up and maintained. They readily accept all sorts of aquarium foods and are fairly easy to breed. They are prone to disease if the water quality is not kept up, so their tank does need regular maintenance. The location of the tank is important too. These fish get nervous and will get stressed it their tank is in areas that are loud, or where there's a lot of traffic around the tank.
Aquarium Hardiness: Very Hardy
Aquarist Experience Level: Beginner
Foods and Feeding
The Powder Blue Dwarf Gourami is an omnivore and will generally eat all kinds of live, fresh, and flake foods. To keep a good balance give them a quality flake or pellet food as the base to the diet. Supplement this with live foods such as white worms, blood worms, brine shrimp, or any other suitable substitute. Vegetable tablets can be offered as well. Generally feed once or twice a day.
Diet Type: Omnivore
Flake Food: Yes
Tablet Pellet: Yes
Live foods (fishes, shrimps, worms): Some of Diet
Vegetable Food: Some of Diet
Meaty Food: Some of Diet
Feeding Frequency: Daily - Generally feed once or twice a day.
The Dwarf Gouramis are hardy fish. Although the labyrinth organ allows the fish to survive in oxygen depleted water, it is a common misconception that this makes water changes unnecessary. This is hardly the case as these fish will suffer the same tissue damage from built up toxins as any other fish. Regular water changes are a must with 25% weekly being recommended.
Water Changes: Weekly - Weekly water changes of 25% are recommended.
The Powder Blue Dwarf Gourami will swim in all parts of the tank, but particularly likes the middle and top portions of the aquarium. These are small fish and a single specimen could be kept in a smaller aquarium of at least 5 gallons. However a 10 gallon tank is recommended as it will suit it much better. There's plenty of space for plants and the water will be more stable, and there will be room for some tankmates as well. It is desirable to keep the tank in a room with a temperature as close as possible to the tank water, or risk damaging the labyrinth organ. The tank should have an efficient filtration system but should not to create too much of a current. Air stones are also recommended for these fish as they prefer well oxygenated waters.
Dwarf Gouramis will show their colors best on a dark substrate. They enjoy an aquarium that gets a good amount of light, but the tank should be decorated in a manner that provides plenty of hiding places for this shy fish to feel safe and secure. If the tank is too sparsely decorated tank they will become shy and withdrawn. These fish appreciate dense vegetation with some floating plants to give some cover. However they will regularly breath air at the surface so its important to have some areas unencumbered with plants. The tank needs to be located in a quiet area as these fish are easily scared by loud noises.
Minimum Tank Size: 10 gal (38 L) - A single fish will need at least a 5 gallon tank, but a larger 10 gallon aquarium is recommended.
Suitable for Nano Tank: Yes
Substrate Type: Any
Lighting Needs: Moderate - normal lighting
Temperature: 72.0 to 82.0° F (22.2 to 27.8° C) - The ideal water temperature is 77° F (25° C). Keeping the surrounding room temperature consistent with the water temperature will help avoid trauma to the labyrinth organ.
Breeding Temperature: 80.0° F - Optimal breeding temperatures are between 80 - 84° F (26 - 29° C).
Range ph: 6.0-8.0
Hardness Range: 5 - 18 dGH
Water Movement: Weak
Water Region: All - These fish will swim in all areas, but particularly in the middle and top portions of the aquarium
Powder Blue Dwarf Gouramis are a good community fish that can be kept with other peaceful fish. Large, active, or aggressive fish can easily intimidate them.They can be timid and may hide when first introduced to an aquarium. It may take some time for them to become comfortable and behave normally.
Although this fish is often sold as pairs, the male may become belligerent to the female. Sometimes a pair can be kept together, but watch for male bullying of the female and provide plenty of hiding places.. Two males, similar to bettas will fight, especially in smaller aquariums. Unless the aquarium is very large and well planted it's best not to keep a mix of Gourami species together or to keep this fish with other anabantoids including Bettas. These types of fish will bring out the aggressive side of this gourami. Avoid housing them with fin nippers and brightly colored species like guppies.
In larger aquariums they can be kept with some of the other gouramis or even some peaceful cichlids. But these companions need to be selected carefully. This gourami simply doesn't do well with tankmates that are too large, too active, or aggressive. It's never a good idea to house these fish with those that are protective of their fry. Protective fish have been known to bully these fish which can eventually cause death.
Temperament: Peaceful - Breeding males can be quite belligerent.
Same species - conspecifics: Sometimes - It is generally not a good idea to keep Dwarf Gouramis together unless breeding or in a very large tank that is heavily planted.
Peaceful fish (): Safe - They do well with other small peaceful fish.
Semi-Aggressive (): Threat
Aggressive (): Threat
Large Semi-Aggressive (): Threat
Large Aggressive, Predatory (): Threat
Slow Swimmers & Eaters (): Monitor - Gouramis can be quick at feeding time. Make sure any fish that are not so quick get fed if you are keeping them with gouramis.
Shrimps, Crabs, Snails: Safe - not aggressive
Sex: Sexual differences
The male is much more colorful and has a pointed dorsal pennant, they also generally have a smaller belly than the female. The female has much less color and her dorsal is rounded or curved.
Breeding / Reproduction
Breeding the Powder Blue Dwarf Gourami is not too difficult, but the behavior of the males can be somewhat unpredictable. It is best to provide a breeding tank, either a 10 or 20 gallons works fine, and keep the water level low at about 6 - 8" (15 - 20 cm). Normal water parameters are fine but raise the temperature to between 80 - 84° F (26 - 29° C). Add a small gently air-powered sponge filter or some peat filtration. They need several fine leaved plants, like Hornwort or Milfoil, along with some floating plants like Ricca for comfort. Sometimes during the courtship and after building the nest, a male may consider females to be rivals and bully them. So the plants are essential for the female to have places for retreat.
A male and one or more females need be well conditioned with small offerings of live and frozen foods several times a day. When well fed, females should begin filling out with eggs, appearing very plump. Add one or more females to the breeding tank several days before the male, preferably in the dark, and continue feeding conditioning foods. Then add the male. Like most fish in this family, male Dwarf Gouramis are bubble nest builders. In an aquarium you will see a cluster of bubbles on the top of the water.
Once the nest had been built the male will begin a courtship display, usually in the afternoon or evening. He will flare up his dorsal fin and begin swimming around a female trying to draw her underneath his nest. If the female is willing she will begin circling with the male. To spawn she will touch the male with her mouth, either on the back or on the tail. The male then embraces the female, ultimately turning her on her back and the female will release about 5 dozen clear eggs. Once the female lays the eggs the male will immediately fertilize them. The eggs are lighter than water and float to the top. The male will pick any not in the nest in his mouth, and put them in his bubble nest. The pair will then spawn again until anywhere from 300 to 800 eggs are produced. If there are other females, the male may spawn with them all.
After spawning remove the females, as the male will become totally intolerant. He will continue to tend the next and guard the eggs until they hatch. The eggs will hatch in about 12 - 36 hours, depending on the temperature, but will stay in the bubble nest and continue developing. They will be free swimming and leaving the nest in about 3 days. At this time the male should also be removed as he may eat the young. Free swimming fry can be fed infusoria or a liquid fry food until they are large enough to eat baby brine shrimp. Separate rearing tanks will be needed as the fry vary in size, and bullying is common in these small environments. See the description of breeding techniques in: Breeding Freshwater Fish: Anabantoids. Also see Fish Food for Fry for information about types of foods for raising the young.
Ease of Breeding: Moderate
Powder Blue Dwarf Gouramis are very hardy so disease is not usually a problem in a well maintained aquarium. Some diseases they are prone to are bacterial infections, constipation and Hole in the Head if good water quality, nutrition, and maintenance is not provided. With any additions to a tank such as new fish, plants, substrates, and decorations there is a risk of introducing disease. It's advisable to properly clean or quarantine anything that you want add to an established tank prior to introduction, so as not to upset the balance.
These fish are very resilient but knowing the signs of illness, and catching and treating them early makes a huge difference. An outbreak of disease can often be limited to just one or a few fishes if you deal with it at an early stage. The best way to proactively prevent disease is to give your fish the proper environment and a well balanced diet. The closer to their natural habitat the less stress the fish will have, making them healthier and happy. A stressed fish will is more likely to acquire disease. For information about freshwater fish diseases and illnesses, see Aquarium Fish Diseases and Treatments.
The Powder Blue Dwarf Gourami is readily available both in stores and online. The males are moderately expensive, with females (or purchasing by the pair) usually being a little less.
Lori - 2011-08-29 I have had 5 Powder Blue Gouramis and they looked good, but they start to get thin and then die. They are eating, don't show signs of disease, then they get listless and die with in days. I have a healthy 55 gallon tank, lots of plants and hiding places. I have Angels, Parrots, Kissing Gouramis, Tetras and Barbs. They all seem to get along, with some spats, but nothing constant. Any suggestions?
Harry - 2012-01-23 How big is your angel? I have gourami and angel mixed tank and to begin with it was a struggle angels at time can be very aggressive Especially when fully grown!!
daryl - 2012-02-16 I have the same problem and the same size tank. My other dwarf Gouramis do great just the powder blues are having a problem.. Wonder what is going on no signs of disease.
ben - 2013-07-14 Hello we got a powder blue dwarf gourami a week ago and everything was fine until earlier today it seems to be having problems staying a float... side fins and tail fin was going like 90 miles an hour and it was barely moving and looked like it was breathing hard or having trouble breathing. And it looks like its tail fin is deformed or something like its tail fin and under belly fin are all in one... we have a red dwarf gourami for a month or more now and it's just fine and looks normal.
Linda - 2014-07-28 I had to stop buying the dwarf gouramis, especially the powder blue ones, which I love. I was told that there is a specific disease that the dwarf gouramis get with some regularity and there was nothing to do about it. They have a weakness for it and when they developed the dwarfs of some of these, they would most often end up with it. A local pet store chain told me she hadn't heard that, but she wasn't well trained either. I decided to wait until someone figured out how to breed these fish without this disease shortening their life. Sorry I am no help except to say, about everyone that has them has told me the same thing although I haven't checked lately to see if these has been any progress.
Frank Delany - 2014-10-26 Sounds like Intestinal Parscites.....see disease chart for remedy
victor - 2014-10-16 Hi I have a blue dwarf gourami which was introduced in my aquarium where i had 2 clown loaches and a sword tail, black tail. i have noticed that the sword tail nips at him when i've put him in and since then is just hiding on the bottom of the tank. Later i've introduced another red gourami ,but his behaviour is still the same,he's not coming up for feeding is just eating plants.Is there anything i can do to help him to become more sociable? please help me
Clarice Brough - 2014-10-17 Having plenty of plants and hiding places can help.
shay - 2014-08-15 I have a powder blue gourami, I'm guessing it a boy since most walmarts don't sell females. I've got him in a ten gallon tank with three barbs, he's very peaceful, eats all the time and likes to swim all over the tank. I do have one barb that likes to nip at his fins every so often which leads to him trying to hide, but not a lot. My issue is on the bottom of his belly and the tip of the fin under his belly he has turned dark blue. I seen it before and it faded back to his normal silver/blue color but this time its been all day. He is still acting the same and eating the same I'm just worried it might not be normal.... What do I do please someone help me out. I've got it heated to 78_80. Got A little air stone filter. Lots of plants and hiding places I might feed him a bit but he's always looking for it on the bottom so I just feed him so he doesn't have to eat nasty stuff ....... I also did just change the tank water this morning cuz it was nasty
Clarice Brough - 2014-08-17 It sounds like you're taking good care of him and he's eating,, so I wouldn't start worrying yet. He could have some stress due to the barbs. It is best to keep barbs in groups of 7-8 so they spend their time nipping each other, and leave the other tankmates alone:)
