I made an aquarium for the terminal, written in Python (needs termcolor module to run). It was a project I wrote to help me learn OOP.

It randomly generates a unique aquarium ecosystem every time you run it.

It adjusts to your terminal window size, so you can run it fullscreen or just have a tiny little aquarium off to the side to keep you company while you work!

Try it out, and let me know what you think :)
