Alien Containment

Aquariums provide an ideal opportunity to study alien fauna up close. Select carefully which lifeforms you bring onboard - they may also be studying you.

― PDA, Dialogue

The Alien Containment is a large, cylindrical aquarium which can be filled with Fauna that has been caught or hatched by the player. It is built using the Habitat Builder inside the Multipurpose Room. The blueprint can be retrieved via a data box.

Building

In order to get inside of, or put fish into the Alien Containment, the player must build a Hatch on one of the sides. The player can then enter the Alien Containment 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 into one bigger tank. 

Uses

If the player leaves 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. Edible Fauna, such as the Peeper, will reproduce approximately twice a day once mature. Once the Alien Containment reaches a population of ten fish, the reproductive process will stop. If more fish are added after the maximum is reached, some will die and float to the top of the container. Multiple Alien Containments stacked on top of each other will increase the amount by ten each.

Eggs can be placed inside the Alien Containment. This can be done by simply dropping the Eggs inside the Alien Containment. Eggs will take about three to five in-game days (sometimes less) in order to hatch. When hatched, the fauna within the eggs will create smaller versions of said fauna, and will grow inside the Alien Containment. Non-edible Fauna can be bred this way to be used as fuel for the Bioreactor. Keep in mind that egg-laying fish will keep laying eggs (so long as there are two or more) and hatching them until the population cap is reached, as stated above.

Flora can be placed inside the Alien Containment, via a Planter UI with sixteen slots that appears when hovering above the soil. This can be used as an alternative to the Exterior Growbed for farming aquatic resources. Tiger Plants will attack certain fish if planted in the Alien Containment, potentially killing the fish and damaging the base. Creepvines will not grow to their full height without stacking Alien Containments.

Aggressive Fauna hatched inside the Alien Containment will have a Passive attitude towards the Player when they enter the Alien Containment, and if they are released into the wild. They will not attack other fauna inside the Alien Containment, but will do so if released into the wild, even other fish hatched inside the Alien Containment. Once released into the wild, Aggressive Fauna will also attack small player vehicles, regardless of whether the player is in them or not, although they lose interest much faster than their wild counterparts.

The Cyclops' sonar does not recognize Aggressive Fauna in an Alien Containment as non-hostile and will thus mark any species that can threaten the vessel, like Ampeels and Crabsquids, as nearby threats.

Data Bank Entry

Despite huge, Alterra-led advancements in stellar technology, exploring new worlds still has its challenges, and alien lifeforms are one of them. That's why we built the alien containment unit. The unit is designed primarily to breed larger or more dangerous species. Technical Provisions: - Units must be installed in multipurpose room modules - Units may be connected between rooms stacked in a column - A hatch must be installed in order to access the unit - The base of the unit is a planter, allowing sea flora to be grown from seed Breeding Tips: - Provided sufficient time and living space, organisms of the same species should mate and reproduce - Eggs inside the unit will hatch over time - Organisms raised from birth in captivity often exhibit unusually passive behavior Warnings: - Environmental controls may fail if the unit is overpopulated - Infections may be transmitted faster between specimens in artificial environments - Never tap the glass: you don't know what will tap back, or how hard

• The former name for the Alien Containment was the Large Aquarium, and before that, the Water Park.
