Ideal Marble Hatchet Fish Conditions


  • The Marble Hatchet Fish is one of the more unique species of colorful tropical freshwater fish because of its unusual shape. The belly of the fish has a round shape to the bottom with the fins situated at the top of the body. The pectoral fins are shaped upward and backward to give the impression of flying.


  • And speaking of flying, they always keep to the top part of the fish tank and can indeed jump fairly high and far out of the water considering their size, so a tank canopy is an absolute must if you want to keep a couple of these in your aquarium. Having plants in your tank that grow near the surface of the water will make them just that extra bit more happy.


  • They are ideal for a community aquarium setup and very peaceful. They tend to be a bit difficult to introduce to their new home but once settled in they are easy to care for. When I say difficult to introduce I don't mean that it can't be done. It is just a matter of taking some extra care when transporting and introducing them.
