Hatchet

Hatchet fish are a popular choice for aquarium enthusiasts, known for their unique shape and peaceful demeanor. These fish can grow up to 5-7 centimeters in length and prefer temperatures between 24-28 degrees Celsius.

Hatchet fish are omnivores and can eat a variety of foods, including flakes, pellets, and live or frozen foods like brine shrimp or bloodworms. They also have a unique feeding behavior where they jump up to the water's surface to catch insects or other prey, so providing some floating food is recommended.

These fish are a great addition to a community tank, but they prefer to be kept in groups of 6 or more to feel secure. Hatchet fish are known for their shy nature, so it's important to provide plenty of hiding places with plants and decorations to make them feel comfortable. Overall, these fish are a fascinating and peaceful addition to any aquarium.
