Alien Containment (Subnautica)

File:Water Park.png

The Alien Containment is a large, circular aquarium which can be filled with Fauna caught by the player. It is built using the Habitat Builder inside rooms.

In order to get inside of or put fish into the Alien Containment, the player must build a Hatch on the side. The player can then enter the Alien Containments and release caught fish into it. Non-edible fish can be added through the use of their respective eggs. If two or more Multipurpose Rooms are stacked on top of each other, building Alien Containments inside each Room will cause the Containers to merge in one bigger tank. 

If you leave two creatures of the same species inside the Alien Containment for long enough, they will breed and another fish of the same species will spawn inside. Once the Alien Containment reaches a population of 10 fish, the reproductive process will stop. If more fish are added after the cap is reached, some will die and float to the top of the container.

Eggs can be placed inside the Alien Containment. Eggs will take about 3 to 5 in-game days in order to hatch. When hatched, the fauna within the eggs will create smaller versions of said fauna, and will grow inside the containment.

Flora can be placed inside the Alien Containment, via a Planter UI that appears when hovering above the soil. Creepvines will not grow to their full height without stacking aquariums.
