Gasteropelecus levis
Silver Hatchetfish
Gasteropelecus levis, known for its unique body shape, is an active, surface-dwelling species. Its compressed, silver body, paired with wing-like pectoral fins, gives it the appearance of a miniature flying saucer. Observing them in a dimly lit tank with floating plants, which mimic their natural habitat, unveils their true elegance and behavior.
**Behavior & Compatibility:**
- Peaceful but somewhat timid, they thrive best in a school of 6 or more, reducing stress and promoting natural behaviors.
- Co-inhabitants should be of similar temperament and size to avoid any undue stress.
**Diet:**
- Predominantly insectivorous, they appreciate a varied diet including high-quality flakes, frozen foods like daphnia, and the occasional live insect or larvae.
**Tank Conditions:**
- Ensure a tightly sealed lid as these fish are proficient jumpers.
- Provide ample swimming space at the water surface and use floating vegetation to offer shelter.
**Breeding:**
- Breeding in aquarium conditions is rare but achievable given optimal conditions—soft acidic water and maintaining group dynamics.
- Mating pairs typically exhibit egg scattering amidst plants.
**Challenges:**
- Being sensitive, these fish require established, stable water conditions.
- Regular monitoring and maintenance of water parameters, including TDS and pH, are crucial for their well-being.
