The Aquarium is a room with an unusual rarity, which defines its spawn rate in the drafting pool. It has a low chance of appearing while drafting, especially in lower ranks. However, as you reach higher ranks during your run, the Aquarium is more likely to appear in your drafting plan. However, to draft the Aquarium, you’ll need to spend one gem. So, ensure you save one if you intend to add this room to your layout.
This room has certain permanent upgrades. If you have got the Aquarium when inserting the Upgrade Disk at the terminal, you can then choose between any of the following upgrades:
- Goldfish Aquarium – Earn 10 gold coins.
- Starfish Aquarium – Earn 1 star.
- Electric Eel Aquarium – Functions as a power source.

The Aquarium Room is a room of every colour, meaning it counts as all types of rooms. This can be incredibly useful if you are dealing with areas or puzzles that require specific room types to activate. Its multi-colour nature also allows you to benefit from all room color-related effects at once.
Additionally, the Electric Eel upgrade allows the Aquarium to power up electricity, much like the Boiler Room. Beyond its function, the room allows you to relax and calm your mind by watching different types of fish swimming inside the tanks.
