Bladderfish: Unique outer membrane has potential as a natural water filter. Health: 30 HP. Behavior: Passive.
Troubleshooting
- ! Can I tame or feed Bladderfish?
Cause: Sub1 had limited tameable species (only Cuddlefish was a true pet). Bladderfish was passive — interaction depended on game mechanics.
- Sub1 baseline: most non-aggressive fish were edible (Survival Knife harvest) and could be raised in Alien Containment.
- Sub2 multiplayer co-op may introduce new interaction mechanics — TBD at launch.
- For breeding: Bladderfish eggs (if available) hatch in Alien Containment with optimal lighting.
- ! Where exactly does Bladderfish spawn?
Cause: Sub2 (Ariadne Arm) is a new planet — exact biome layouts ship May 14, 2026.
- Sub1 reference biomes: TBD.
- Sub2 likely places Bladderfish in equivalent ecological niches.
- Confirmed spawn data updates within 24h of Early Access launch.
