Tanks & the safe nursery.

The active tank joins battles. Other tanks keep their residents safely outside that encounter, and inactive care is frozen. Tank upgrades add visible swimming terrain, resident capacity and reef structure spaces. An individual fish card chooses its home. The nursery safely holds extra residents and recovers hunger-collapsed fish during active aquarium time. A full active tank needs a swap before another individual can join or become the pilot.
