Hockeystick pencilfish Breeding Guide

Breeding Hockeystick Pencilfish (Nannostomus eques) is a challenging endeavor that requires precise attention to water conditions and tank setup to induce spawning. While these fish are occasionally bred by advanced hobbyists, they are not commonly bred in captivity on a large scale.

Creating a Breeding Environment

To encourage breeding, set up a separate breeding tank with soft, acidic water, mimicking the conditions they thrive in naturally. The pH should be between 5.5 and 6.5, and the temperature should be maintained at the higher end of their comfort range, around 26°C to 28°C. Subdued lighting and densely planted areas with fine-leaved plants such as Java moss or spawning mops can provide the right environment for egg deposition.

Preparation and Spawning

Priming the breeders for spawning involves conditioning them with a rich diet focused on live foods. Gradually increase their intake of high-protein foods such as live daphnia, bloodworms, and brine shrimp. The combination of increased nutrition and ideal water parameters should stimulate spawning behavior. When ready to spawn, the male and female will engage in courtship displays. The female may release her eggs among the plants or substrates, which the male will fertilize.

Post-Spawning Care

Once spawning has occurred, remove the adult pencilfish from the breeding tank to prevent them from eating the eggs. The eggs will generally hatch within 24 to 36 hours, depending on the water temperature. Fry are very small and require infusoria or specially prepared fry food at the start. As they grow, baby brine shrimp and finely powdered flakes can be introduced into their diet.

Care of the Fry

Raising the fry requires maintaining pristine water conditions, as they are particularly sensitive to changes in water quality. Regular but gentle water changes are crucial to prevent any accumulation of harmful substances. Gradually increase the tank's brightness as the fry grow, and ensure that plant cover is maintained to provide a sense of security.

Breeding Hockeystick Pencilfish is a rewarding challenge for aquarists familiar with their care needs and willing to invest the time and effort into creating the right breeding conditions. Observing the fruition of color and activity into a new generation is a fulfilling experience, providing an opportunity to witness the fascinating life cycle of this distinctive species.
