nerfische

Nerfische is a fictional genus of small freshwater fish created for speculative biology and world-building. In the imagined ecosystem where it appears, nerfische are a common component of lake and slow-flowing river communities in the Nerida archipelago, and they are frequently encountered in field guides within that setting.

Morphology and habitat: Nerfische range from 4 to 6 cm in length. They have a laterally compressed body, silvery flanks, and fins that are often pale yellow. The species typically inhabit the limnetic zones of cool lakes and quiet streams, where emergent vegetation provides shelter and spawning sites.

Ecology and biology: They are omnivorous, feeding on plankton, algae, and small invertebrates. Schooling behavior is prominent, especially in juveniles, providing protection from predators. Reproduction is oviparous, with adhesive eggs laid on submerged vegetation in spring. Parental care is not recorded in standard in-world accounts.

Taxonomy and conservation: Nerfische is a fictional taxon and does not correspond to any real-world species. In-world literature sometimes divides it into several described species with regional variants. The conservation status within the fictional setting is generally stable, though habitat disturbance and invasive species are cited as potential threats in localized areas.
