Hybrid Aquatic is a Java mod for Fabric, Forge, and NeoForge that turns oceans, rivers, and swamps into living ecosystems. Available for Minecraft 1.19.2 through 1.21.1, it adds dozens of new species, from great white sharks and hammerheads to barrel jellyfish, sea nettles, and schools of mackerel. New environment blocks including sargassum mats, bull kelp forests, and deep-sea thermal vents reshape underwater exploration so that each biome feels distinct when you dive in.
What Hybrid Aquatic Adds
New creatures spawn in specific biomes. Sharks patrol open oceans and deep lukewarm zones: great whites, hammerheads, tiger sharks, and basking sharks each occupy their own territory. Schools of mackerel appear near Ocean Monuments, dragonfish roam the trenches, and barrel jellyfish and sea nettles drift in shallower water. Sunfish occasionally dive through brighter surface layers. Because each species is biome-specific, the water body you explore determines what you encounter.
Alongside the creatures, the mod adds aquatic plant life and geological features. Floating sargassum patches appear in deep lukewarm oceans, jungle lily pads spread across warm rivers, and meadows of red algae grow along lukewarm ocean floors. Bull kelp forests and standard kelp variants fill mid-depth zones. On the deepest seafloor, thermal vents spawn with surrounding tube worms. All of these generate naturally in new and existing worlds without any configuration.

Questions about this entry.
How do I install Hybrid Aquatic?
Download the Hybrid Aquatic jar from Modrinth and place it in your .minecraft/mods folder. You need Fabric, Forge, or NeoForge installed for the Minecraft version you are playing. No extra library mods are required. For multiplayer, install the mod on both the client and the server so creatures and blocks generate and appear correctly.
Does Hybrid Aquatic work on multiplayer servers?
Yes, Hybrid Aquatic supports multiplayer. It is a client-and-server mod, so both the server and each player's client must have the mod installed. The new ocean creatures and blocks exist in server-side world data, and players without the mod will not see them correctly. Vanilla clients cannot join a server running Hybrid Aquatic.

Hybrid Aquatic supports Minecraft 1.19.2, 1.19.4, 1.20.1, 1.20.2, 1.20.4, and 1.21.1. Each game version has separate Fabric, Forge, and NeoForge jars. The latest maintained release targets 1.21.1. Visit the Modrinth page to download the correct jar for your version and loader combination.
What new creatures does Hybrid Aquatic add?
Hybrid Aquatic adds ocean predators including great white sharks, hammerhead sharks, tiger sharks, and basking sharks. It also includes barrel jellyfish, sea nettles, schools of mackerel, dragonfish, and sunfish. Each species spawns in a specific ocean biome or depth zone, so exploring different underwater areas reveals different creatures.
Does Hybrid Aquatic require Fabric API?
No, Hybrid Aquatic does not require Fabric API or any other library mod. Only the Hybrid Aquatic jar and your mod loader are needed. This applies to all supported loaders: Fabric, Forge, and NeoForge. The project page on Modrinth lists no required dependencies.
