Features:
- Expands the aquatic world with dozens of fish and aquatic creatures that naturally occur in suitable biomes – from the deep, cold ocean to rivers, swamps, and tropical coral reefs.
- The mod adds traps that you can place underwater and feed with Rotten Flesh to automatically catch fish while you do other things.
- The mod supports fish hatcheries – devices placed in shallow water to raise fish from buckets over time, creating an active aquatic breeding source.
- When fishing, you can find new loot such as pirate treasure, empty boxes, fish bones, or fossils in addition to normal items.
- Players can decorate the world with underwater-themed paintings (custom paintings) added by the mod
