This species is native to a tropical environment. The maximum recorded length of the Oryzias mekongensis as an unsexed male is about 3 centimeters or about 1.18 inches. The upper and lower edge of their caudal fin is known to be with bright orange margins. it is known to occupy shallow, permanent standing water of ditches, canals, and ponds. This species is mainly found in water that has a lot of growth of submerged aquatic plants with divided leaves. When it comes to their diet, they are known to feed on plankton. The Oryzias mekongensis is only caught with fine-meshed nets or when larger nets pull out large amounts of plants, which allows the fishes to get trapped in them. This species of fish is not used in the markets for consumption. This species is also not considered to be an annual breeder. Although it is possible, it is known to be very difficult to maintain this species in an aquarium. It is used for commercial use.[1] This species been recorded to have been collected mainly from clear water swamps that might possibly contain acidic water.[2] The major threats to this species' population rate would include habitat destruction and degradation that is primarily caused by urban development and also agriculture.
