Why is it called a three spot Gourami?
Why is a blue gourami, or three-spot gourami, called a 3 spot gourami when it only has two spots? Well, yes, the three spot Gourami does only have two dots on its body, but then the eye is considered the third spot.
The three-spot Gourami derives its name from the dots along its midsection, which if you include the eye, gives the appearance of 3 spots. Some species have elaborate stripes and patterning, but the 3-spots can clearly be seen underneath.
Three-spot gourami, Trichopodus trichopterus, can be found mainly in the River Mekong basin in southern China, Vietnam, Laos, Cambodia, Thailand, Myanmar and Malaysia, and also in parts of northern Indonesia.
