Fishy.py has a database with more than 16,000 fishes, thanks to https://www.fishbase.org/! All of them have unique images and names. When you fish, one is randomly selected from the database. However, in the future [v2], when you have a higher level you have a higher probability of catching more rare and uncommon fish! In terms of technicality, Fishy.py is made with the discord.py API, which is a wrapper for the Discord API. Fishy.py also using sqlite3 for the database.
