Description: The Spotted hatchetfish has a convex body. The ventral fins are very small and the back is fairly straight. The wing-like pectoral fins are transparent and often measure up to one-half the fish's overall body length. The coloration is silver and the back is olive brown.Small black spots cover the body. Since the species is a schooling fish five or more should be kept in a tank. Females are plumper during spawning season.

When the animals are fed well the aquarium should be darkened. The water should be soft and acid. The eggs are laid between the roots of floating plants and fertilized.  The eggs fall to the bottom. After spawning the parents should be removed.  After 30 hours the eggs hatch and after 5 days the young fishes are swimming free.  You should feed them very fine infusoria. After 7 days you can give them Artemia-nauplii.
