The Bubbulator is an upgrade from The Fish Emporium for the Virtual Tank. Of the four upgrades that must be purchased in order, the Bubbulator is the first in line.


By providing more oxygen for the fish, up to 20 fish can be housed in the tank up from the original capacity of 10. Players have the option to hide it from view in the Tank menu but its capacity-increasing effects will remain. By pressing the "B" key on the keyboard, players can cause the Bubbulator to visually function and produce bubbles.


  • The Bubbulator is based on a bottle-like aerator in real world.
