Alien Containment (Subnautica)

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 Alien Containments.

Despite huge, Alterra-led advancements in stellar technology, exploring new worlds still has its challenges. Alien lifeforms are one of them. The alien containment facility is designed to mimic the natural environment outside the habitat, and facilitate scientific research.

Units must be installed in multipurpose room modules, and may be connected between rooms stacked in a column
A hatch must be installed in order to access the containment unit
Flora and fauna may be kept alive indefinitely, provided a steady food and power supply
The containment unit provides a perfect environment in which to study alien feeding and breeding behaviors
Environmental controls may fail if the unit is overpopulated
Never tap the glass: you don't know what will tap back, or how hard
