Introduction to Blue Gourami

Blue Gouramis are a popular species of freshwater fish that are known for their stunning appearance and ease of care. These fish are native to Southeast Asia and are prized for their brilliant blue coloration.

In this article, we will discuss everything you need to know about Blue Gourami care, including their appearance, lifespan, tank size requirements, water parameters, feeding, behavior, and breeding.

Species Summary

Blue Gouramis, also known as Three-Spot Gouramis, are part of the Osphronemidae family and originate from Southeast Asia. They are a peaceful species that are known for their calm and gentle demeanor.

Blue Gouramis have a labyrinth organ that allows them to breathe air directly from the surface of the water, allowing them to survive in oxygen-poor environments.


As their name suggests, Blue Gouramis are characterized by their striking blue coloration. Males are typically more vibrantly colored than females and have a brighter blue on their bodies.

They also have distinctive three black spots across their bodies. Females tend to have a more subdued blue color, and their spots are less prominent.

Both males and females have long, flowing fins that add to their overall elegance.


With proper care, Blue Gouramis can live for up to five years in the wild. In captivity, they can live for up to seven years.

However, their lifespan can vary depending on factors such as water quality, diet, and tank size.

Average Blue Gourami Size

Blue Gouramis can grow up to six inches in length. Females tend to be slightly smaller than males, growing up to four inches in length.

Care Guidelines

Tank Size

When keeping Blue Gouramis, consider that they require adequate space to swim and have ample room for proper filtration. It’s recommended that you keep at least one Blue Gourami in a 20-gallon tank, with an additional ten gallons per additional fish.

This allows the fish to have enough space to grow and establish territories.

Water Parameters

Blue Gouramis require freshwater conditions with a pH range between 6.0 and 8.0 and a water hardness level between 5-20 dGH. Ensure that you maintain a consistent water temperature between 75-82F.

What to Put in Their Tank

When decorating their tanks, consider incorporating hiding spots such as plants and caves for them to retreat to when feeling stressed. Providing an environment with plenty of natural cover will help to reduce stress levels in Blue Gouramis.

Live plants, such as java moss and hornwort, can help to maintain water quality and oxygenation in the tank and will enhance the appearance of their habitat.

Potential Diseases

Blue Gouramis are relatively hardy fish but are susceptible to a few common illnesses that affect freshwater fish. These include bacterial infections, fungal infections, and parasitic infections.

Keep an eye out for symptoms such as lethargy, loss of appetite, and abnormal swimming behavior. If you suspect that your fish may be ill, seek professional advice immediately.

Food & Diet

Blue Gouramis are omnivores and require a diverse diet to maintain their health. They are known to eat a range of foods, including flakes, pellets, frozen, and live foods.

Providing a varied diet will prevent deficiencies and ensure their nutritional needs are met. Feed them twice a day, only giving them what they can consume within a few minutes.

Behavior & Temperament

Blue Gouramis are peaceful and generally get along with other fish. They can be kept with a variety of other freshwater fish, including tetras, rasboras, and dwarf cichlids.

However, it’s important to ensure they have enough space and hiding places to reduce aggression levels. They have a calm and gentle demeanor and are a great choice for beginner aquarists.

Blue Gourami Tank Mates

When choosing tank mates, consider the fish’s compatibility with Blue Gouramis. Avoid keeping them with aggressive or fin-nipping species.

Good tank mates for Blue Gouramis include other peaceful fish such as Corydoras, Danios, and Guppies. It’s essential to provide adequate space and hiding spots for all the fish in the aquarium to reduce aggression levels.


Blue Gouramis are relatively easy to breed. To encourage breeding, raise the water temperature to around 82F and provide plenty of hiding spots and plants for the female to hide and lay her eggs.

The male will build a bubble nest, and once the female has laid her eggs, he will fertilize them and proceed to protect the nest. Once the fry has hatched, ensure that you provide them with plenty of small foods such as crushed flakes and brine shrimp.

In conclusion, Blue Gouramis are a stunning species of freshwater fish that are easy to care for and make an excellent addition to any aquarium. By providing them with adequate space, water quality, and a varied diet, you can ensure that they live a happy and healthy life.
