FabricClient and serverMIT LicenseOpen source1.20 – 1.20.1

What it does

Both mobs spawn in Nether biomes, including biomes added by other mods. Their only item is a spawn egg, and the mod adds nothing else to the world, so a player can keep playing an existing save without changes. Mob icons are included for Xaero's Minimap. The mod runs on client and server, and Fabric API is required; Sinytra Connector is optional. It is released under the MIT License and is open source, with Fabric files for 1.20 – 1.20.1, latest 1.1.0 for 1.20.1 from 2026-01-07.

What the author says

BetterNether is a great mod, but one of its best features is its two ambient mobs: the firefly and the hydrogen jellyfish. Those two mobs and their spawn eggs are the only thing the mod features, so you can continue playing in your world without the rest of the BetterNether stuff if you don't want it there.
