Characteristics of the rare stream fish
The Mát fish usually forages at night, starting when it gets dark, following the herd. They eat insects on the water surface, algae stuck to rocks, or red worms (used as bait by the locals). The lower jaw of the Mát fish is very hard and sharp, so when eating, the fish just needs to swim close to the rocks under the flowing water, flapping strongly, causing small white marks on the stream rocks.

The Mát fish grows quickly and appears more during the dry season from April to June. The male Mát fish has a slender body, a black back, a hunched belly, and when mature, it will have rough spots on the upper lip and the anal fin, which can be seen with the naked eye.
The female Mát fish during the breeding season is larger than the males, with red scales; a larger belly, a thinner and softer abdomen; has small sharp spikes on the upper lip but they are very small and hard to observe. The Mát fish is agile and clever during the day, making it difficult to catch, so people usually go fishing at night with a fish hunting gun.
The Mát fish is a rare and valuable specialty fish (with a price ranging from 120,000 to 150,000 VND/kg for a 200g fish). The fish meat is white, fragrant, non-fishy, healthy and rich in nutrients, the fish bones are very hard and few, and the fat is delicious, which is favored by many people.
