Three-Spot Gourami
Trichopodus trichopterus · also called three-spot gouramis, blue gourami, gold gourami
Sweeping a pair of long, thread-like feelers through still, weedy water, a three-spot gourami carries a naming quirk few new aquarium keepers ever notice, since only two of its three namesake “spots” are actually spots at all.
Overview
The three-spot gourami, Trichopodus trichopterus, is a hardy, adaptable labyrinth fish native to still and slow-moving wetland habitat across mainland Southeast Asia and parts of the Indonesian archipelago. Its status as the wild ancestor of the popular blue and gold aquarium colour varieties, tolerance for a wide range of water conditions, and successful establishment well beyond its native range make it one of the most widely encountered gouramis in the world, whether in the wild, on a fish farm, or in a home aquarium.
A name built on a technicality
The three-spot gourami’s name comes from an eye counted as a spot: two genuine dark body spots plus the eye add up to three, a small naming quirk that has stuck across generations of aquarium keepers despite the visible spot count being only two.
Status
Least Concern, remaining widespread and abundant across suitable wetland habitat throughout Southeast Asia, with additional established populations well beyond its native range.
Three-Spot Gourami: common questions
Why is it called the three-spot gourami when it only has two spots?
This species has two dark spots along the side of its body which, together with its eye, are counted as a third spot, giving rise to the somewhat unusual logic behind a common name that has stuck despite only two spots being visible on the body itself.
What is the difference between a three-spot gourami and a blue gourami?
The blue gourami is simply a selectively bred colour variety of the three-spot gourami, developed through generations of captive breeding for aquarium use, along with other varieties such as the gold gourami, all originating from the same wild species.
Has the three-spot gourami spread beyond its native range?
Yes, this species has been introduced well beyond its native Southeast Asian range for aquaculture and the aquarium trade, and it has become locally established in several regions far from where it naturally occurs.
What does a three-spot gourami eat?
This species is an omnivore, feeding on small aquatic invertebrates, insect larvae, algae, and plant matter foraged throughout still or slow-moving water, a flexible diet that has helped it adapt readily to both wild habitats and captive aquarium conditions.
