Compatibility: Most hatchetfishs are peaceful fish that mix well with other species. Keep in shoals, as these fish are very nervous alone, and prone to jumping. Community tanks with small to medium sized community fish (other small community fish), planted aquaria. Good tank companions include Apistogrammad, Corydoras, Angelfish, tetras, Loricarids, small Doradids, and Killifish.
They tend to be a upper-level fish, often swimming directly below the surface of the water.
They can be sensitive to water conditions. Be careful on water changes.
Recommended in groups of 10 or more.
They can propel themselves out of the water and at least assist their flight by rapidly striking their pectoral fins to evade predators, albeit only for distances of a few meters and in a straight line.
Feed them food that sinks. These fish cannot eat from the middle or bottom of the tank.
