[b][i]An incremental game with relaxing gameplay. Breed fish, decorate, and customize your aquarium. Offline progression is supported.[/i][/b] Gameplay: https://youtu.be/JMGVKJ5VxNs In this game, you breed fish and keep them happy. Their joy are an in-game currency, which you can use to buy fish eggs, food, backgrounds, boosters, plants, and aquarium decorations. You can also purchase small containers for breeding fish, upgrade, and unlock new aquariums. Each fish has its own preferences for water temperature, salt content, and lighting levels. You don't need to keep the game open or minimized in the background. Your fish continue to enjoy themselves, generating in-game currency, even if you've turned off the game and are offline.

This game is really cute although I got immediately overwhelmed with the amount of text on the page when i was trying to figure things out. I love the fish designs i cant wait to see how this game develops and changes over time.
My breeding aquarium. Pretty straight forward idler where you amass fish to the point of tank destruction, sell them, and use the money to keep doing that. I recommend this game if you like fish and breeding fish like a puppy mill.
So far I have been having a lot of fun playing My Joyful Aquarium. I really enjoy that you get to decorate your aquarium and that you don't have to worry about cleaning it. I love that I can breed the fish and add different combinations to my tanks. I also really like that you can run this in the background while working or doing other tasks. It is really relaxing watching all of the fish swim around the tank. I definitely recommend giving this game a try.
You can breed some really pretty fish in this game, though I was initially confused, thinking it's a puzzle-breeding game like Fish Tycoon, but actually it's an idle game where you try to create a particularly pretty tank of fish and decorations, which ideally you would display on a tv or spare screen while doing other stuff.
it's cute and fun.. the index is confusing and wonky
