# Aquarium

### Aquarium Configuration

The aquarium can be placed and used by players to **store fish** and **increase their weight over time**.

#### How It Works

* **`max_fish`** – Maximum number of fish that can be placed in the aquarium.
* **`base_growth`** – Amount of weight a fish gains per minute. For example, `1` means the fish gains +1kg every minute while in the aquarium.
* **`notification`** – Messages displayed to the player:
  * `PLACE` – When an aquarium is placed.
  * `BREAK` – When an aquarium is broken.
  * `BAD` – When the aquarium contains fish and cannot be broken.
* **`aquarium_item`** – The item representing the aquarium that can be placed in the world. [LiteItem](/paw-studio-docs/overview/liteitem.md)
* **`water_material`** – Materials used to simulate water inside the aquarium. Multiple materials can be combined for color effects.
* **`gui`** – Default GUI when opening the aquarium
