Characteristics of Blue Gourami

A Blue gourami is a great addition to a freshwater tank that is 30 gallons or more.  These hardy fish are semi-aggressive so only one male should be kept per tank because the males will likely fight with each other.  The females are slightly larger than the males and tend to be more peaceful.  Trichopterus is the scientific name for this fish and comes from the Greek work trichias which means hairy and the Greek word pteron which means wing.  This is in reference to their long hair-like pelvic fins.


The Blue Gourami has an elongated and somewhat compressed body shape.  They are a beautiful blue color with rounded fins.  They can sometimes have a patterned coloration.  One interesting fact about these fish is that their blue coloration can lighten and darken depending on their mood.  These fish will also have two dark spots on their body.  Gourami may reach up to six inches in length.


The Blue Gourami is a labyrinth fish just like Siamese Fighting fish which means that it has a labyrinth organ that allows it to breathe atmospheric oxygen.


These fish are not picky eaters at all.  They will eat flake food, frozen food, veggies, or even live food.   This means that you will want to make sure that you are not keeping a gourami with small fish that are bite-size.

Water Conditions

Gourami do not appreciate a strong current in a tank.  The water temperature should be between 77 and 86 degrees Fahrenheit.  This water temperature should preferably be close to the temperature of the room as the labyrinth organ may potentially be damaged otherwise.  These fish prefer a pH between 6.0 and 8.8.


This fish will be more comfortable in a well planted aquarium as that is what their native habitat is like.


Blue Gouramis breed using a bubble nest.  The male will first make the bubble nest before mating with the female.  After the eggs have been fertilized, the female should be removed from the tank because the male may hurt her.  The male will take care of the eggs until they hatch.  After hatching, the male should be removed from the tank and the babies should be fed food specially designed for these fry.

Life Span

With proper care these fish should live between four and eight years in an aquarium.

These fish will add interest and beautiful color to your tank.
