Linux Candy: Rusty Aquarium – monitoring by visualization

Last Updated on May 25, 2022

In Operation

Here’s a short video of Rusty Aquarium in action.

Floating around the aquarium are a crab (dubbed a happy rustacean), a clownfish (called Nemo), an angelfish, goldfish, seahorse, royal gramma (also known as the fairy basslet), butterflyfish, lionfish, turtle, a neontetra, yellow angelfish, and a zebrafish.

Of course, a crab is a crustacean not a fish.

The next video shows available the keyboard shortcuts (press H to bring them up).

As you can see, there aren’t many keyboard shortcuts. You can populate the aquarium with more/fewer fish. You can also list the different fish in this aquarium although it’s not complete.

There are actually lots of configuration options available which let you change many parameters. We can change the size, speed and bubbles of each fish/crab as well as its movement, collision aversion, speed, and much more. You’ll need to be willing to edit the text file assets/config.json.


Rusty Aquarium is a harmless but colorful graphical aquarium. For those that prefer ASCII aquarium, you may prefer ASCIIQuarium.

We’ve added Rusty Aquarium to our Linux Candy series, a compilation of articles covering interesting eye candy software. We only feature open source software in this series. The table at the bottom of this page offers access to all the programs in this compilation.
