Gasteropelecus sternicla is an ideal fish for the planted aquarium due to its schooling behavior and peaceful nature. Not only does this species require a hooded aquarium to prevent jumping, but also a healthy population of six or more individuals to thrive. Furthermore, excellent water quality is essential to ensure that this fish stays healthy and lives a long, happy life. To get the most out of this species, be sure to provide plenty of hiding places, such as driftwood and rocks. Additionally, include a few floating plants to create a natural looking environment.
The Silver Hatchet’s breeding habits have yet to be fully documented, however, it is speculated that they breed in soft water and a low pH. Furthermore, research has indicated that providing them with a healthy diet consisting of fresh mosquito larvae and fruit flies can be beneficial in triggering spawning. In addition, eggs have been observed on floating plants in the wild, further suggesting that this species may deposit eggs in such locations. With further research, more insight can be gained into the breeding habits of this fish. By understanding the needs of this species, the Silver Hatchet can be successfully bred in captivity.
The Silver 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.
