    Diet & Nutrition: In the wild, Silver Hatchets are carnivores feeding on micro invertebrates and zooplankton at the surface. A diet made up of various high quality protein based flake foods or floating pellet foods is ideal, in addition to offering bug bites and frozen foods such as bloodworms, brine shrimp and daphnia.

    Breeding & Spawning:  Egg layers, however, there is very little information available on breeding and at this time, there are no dependable resources detailing their breeding behavior.

    Gender: These fish can be relatively difficult to sex, but the females are noticeably rounder than the males, especially when they are laden with eggs.
