Origins: Flying Fish

Flying Fish is an origin layer for the Origins mod, so it needs Origins and Pehkui to run. Its core concept is a fragile creature suited to water that can glide briefly above the surface. Oxygen is the key resource: a blue bar from 0 to 100 that refills while the player is submerged and drains by one point per second on land. At 0 the player takes drowning damage, and a warning appears at 20, accompanied by bubble particles and gasping sounds.

The origin's passive abilities include water breathing and night vision, both granted underwater as stacking status effects with hidden icons. Underwater, the player swims at double speed and can break blocks at normal mining speed. Partially submerged or wading, movement speed also doubles, and moving through water or sprinting on the surface leaves splash particles. Built-in elytra let the player glide without an elytra item, at a cost of one oxygen per second in flight.

The mod is server-side only, so only the server needs to run it. Flying Fish is released under the MIT License and is not open source. Files target 1.20.1 on Fabric and Forge, first published 2026-03-12 and last updated 2026-03-13.
