Aquarium (Subnautica)
The Aquarium is an in-development Placeable Item that can be placed inside the Cyclops or inside a Seabase module using a Builder. It currently does not function but it is presumed to be able to hold small Life Forms in the future. Due to its size the only seabase module that it can be constructed in is the Room and the Observatory.
