✨ Key Features
📊 Pros & Cons
✅ Pros
- Turns your Alien Containment into a menagerie of normally uncatchable creatures—Reapers and Warpers included.
- Mini-sized leviathans are adorable and make for great screenshots.
- Peaceful AI means no surprise attacks while you're admiring your collection.
⚠️ Cons
- Only 39 endorsements—small community, so troubleshooting help might be scarce.
- Last updated June 2026—could break with future game patches.
For Subnautica players who've maxed out the standard aquarium and want to show off rare, dangerous creatures safely. Skip if you prefer vanilla gameplay or don't care about cosmetic creature displays.
💡 Beginner Tips
- Make sure you have an Alien Containment built and powered before placing creatures.
- If you're using other mods, load Universal Aquarium after them to avoid conflicts.
- Use the in-game screenshot mode to capture your mini leviathans in action.
