🐟 Fish live on your desktop!
Your desktop turns into a cozy aquarium where fish swim over your games, your work, or whatever you’re doing, bringing a gentle and playful vibe to your day.
Designed for idle play, Desktop Fishes lets you enjoy a relaxing aquarium experience at your own pace. Your fishes will thrive even when you're busy doing other things
Every fish starts as a tiny egg. You’ll see them wiggle, hatch, and slowly grow into adults — each stage is its own little moment to enjoy.
Give your fish some style with hats, glasses, and fun accessories, making each one feel unique and full of character.
Let your fish reproduce and pass down traits to their babies. Some inherit colors and patterns from their parents, while others show up with rare mutations. There are over 10,000 possible genetic combinations!
Your aquarium grows seaweed fast, and it’s up to you to cut it back! Luckily, your fish munch on the extra plants, helping you keep the tank clear and lively.
A strange but merchant with plenty of goods. Buy food, toys, and odd accessories that add charm (and weirdness) to your aquarium.
Expand your aquarium through a set of upgrades. Unlock perks, change the behaviour of your fish, and customize your experience however you want!
Choose how your aquarium lives on your desktop. Let the fish swim over your windows like an overlay, or place them behind everything as a living wallpaper.
Dive into the fun, explore endless fishy combinations, and bring your desktop to life with your own vibrant, swimming friends!
