Description: An elongated species with a fan-shaped caudal fin. The color depends entirely on the population. Two variants are most often seen; a green and a golden type. The green variant has a base colour of green with overlaying red spots and stripes. The lower parts are blue and the belly is white.  The fins are green with red markings and have a green edging. Females are reddish-brown. The golden race has an shiny olive-brown back, and green-gold to blue-gold flanks. The front part of the body is marked with dark red spots, while the rear part has several dark red, transverse stripes. The fins of this morph are green-gold in color and red splotches mark them. Females are brown-gold.

The males are more brightly coloured than females, and males are also being larger. Breeding is possible in a small tank: at least two gallons of water per pair. Add a tank bottom of thick peat since the fish bury their eggs. After spawning press excess moisture from peat and keep it in plastic bags for 4 to 6 weeks at temperatures between 18 and 20 °C. Do not let the peat dry. Be sure to air out the bag periodically. Add soft water to hatch the fry. Feed them with small live food such as Artemia nauplii.
