Cultivation

  Arrange an aquarium with lots of vegetation, a few roots and somewhere open space for swimming, water depth 20-40 cm. They can be accompanied by live-bearing animals, carcinids, razors and catfish that occupy the lower part of the aquarium, the fish of its area are: Oryzias nigrimas,   Oryzias nebulosus,  Mugilogobius sarasinorum, ... Always have a group of fish, one male and several females. Males are quite impatient and aggressive with each other. With a large enough aquarium and many hiding places and strong planting, we can have more males, other fish are in principle safe from attacks by territorial males. The fish have an elongated life, squeezed from the side. The upper jaw is slightly shorter than the lower, where it has a fleshy appendage.  Males have red with black bordered fins. Very similar  are species (Nomorhamphus brembachi and Nomorhamphus liemi) that differ mainly in color  (species are in different basic color shades of silver, blue, green and yellow, red fins have a black edge). The aquarium should be well covered because they like to jump out of the water.
