The Marble Hatchet is an active species of fish native to South American rivers. It is a member of the Gasteropelecidae family and prefers a heavily planted aquarium. To ensure the Marble Hatchet’s health and safety, the aquarium should contain a few floating plants beneath which they can hide, and an aquarium hood to prevent them from jumping out of the water. In order for the Marble Hatchet to thrive, it is recommended to keep a school of six or more individuals, and to maintain excellent water quality. Furthermore, regular water changes and proper filtration are essential for maintaining a healthy aquarium.

The Marble Hatchet is a species that thrives in soft water, with a low pH of about 6.0. To encourage breeding, a diet of fresh mosquito larvae and fruit flies should be provided. Spawning and egg depositing will occur within 36 hours. To ensure successful fry development, hatching fry should be provided with a high quality live food, such as brine shrimp. Furthermore, to achieve optimal growth and health, maintaining consistent water parameters is highly recommended. Additionally, regular water changes are necessary for a healthy environment.

The Marble Hatchet is a carnivore and will eat floating foods such as freeze-dried bloodworms and tubifex, high quality flake food, mosquito larvae, small flies, and some other meaty live or frozen foods.
