Why aquarium matters
It gives fishing a long-term reason to matter. Catching more species and rarer fish improves display goals and passive rewards.

Player tips
- Display rarer fish when passive essence matters more than decoration.
- Feed the aquarium before long sessions so mood does not reduce generation.
- Use species milestones as a collection roadmap before paying essence alternatives.
