Your desktop icons remain visible and fully usable while colorful creatures move naturally through the aquarium.
Your desktop stays productive. Your aquarium stays alive.
🐠 A Cartoon Aquarium That Lives on Your Desktop
DeskAquarium isn't a video playing in a window.
It is a live animated aquarium wallpaper designed to run directly behind your Windows desktop icons.
Watch fish cruise across the screen. See schools form and change direction. Follow a turtle as it glides through the water. Watch jellyfish drift gently through the blue while crabs and shrimp explore the seabed.
The creatures move dynamically in real time, creating an aquarium that feels alive rather than a simple repeating animation.
And because DeskAquarium runs behind your desktop icons, you can continue using Windows normally.
- Open folders
- Launch applications
- Move files
- Browse the web
- Work or study
Your icons remain visible and clickable while the aquarium quietly comes to life behind them.
It's a wallpaper, an aquarium, and a little underwater world — all in one.

🌊 20 Living Sea Creatures
Meet a colorful collection of 20 hand-crafted cartoon sea creatures, each with its own appearance, movement style, and behavior.
Your aquarium can include:
- 🐠 Schooling fish
- 🐟 Angelfish
- 🐡 Bettas
- 🐠 Goldfish
- 🦈 Shark
- 🪽 Rays
- 🐢 Sea turtle
- 🪼 Jellyfish
- 🐴 Seahorses
- 🐙 Octopus
- 🦀 Crabs
- 🦐 Cleaner shrimp
- 🐚 Hermit crabs
- And other colorful underwater residents
Different creatures move in different ways, giving your aquarium a lively mixture of motion and personality.
They don't simply cross the screen. They behave like residents of a living cartoon aquarium.
🐟 They Swim. They School. They Behave.
The aquarium uses real-time movement instead of simply replaying a fixed animation.
Natural Schooling
Schooling fish can:
- Maintain natural separation
- Align their movement
- Stay together as a group
- Spread apart
- Regroup
- Change direction together
A school can continuously change formation as it travels through the aquarium.
Individual Movement
Not every creature follows the same behavior.
Individual animals can cruise, wander, glide, drift, or explore independently.
Natural Fish Animation
Fish use smooth body movement to make their swimming feel more organic.
- S-shaped body motion
- Smooth body bending while turning
- Animated fins
- Natural direction changes
- Individual movement patterns
- Group schooling behavior
The result is a cartoon aquarium with natural-looking movement and constantly changing activity.
🎨 A Beautiful Cartoon Underwater World
DeskAquarium combines a colorful cartoon art style with detailed animation and underwater atmosphere.
The creatures feature:
- Smooth body gradients
- Subtle back shading
- Glossy highlights
- Gradient fins
- Clean outlines
- Detailed gill lines
- Expressive eyes
- Pupils and catchlights
- Distinctive colors and patterns
The visual style is playful and colorful while remaining comfortable enough for everyday desktop use.
It's designed to make your desktop feel alive without overwhelming your workspace.
☀️ An Immersive Aquarium Environment
The aquarium isn't just a collection of animated fish.
The underwater environment also moves and changes around them.
Underwater Light
Soft volumetric light rays descend from the water surface, creating a sense of sunlight filtering through the water.
Depth Fog
Distant creatures gradually fade into the blue, creating greater depth and a more immersive underwater atmosphere.
Soft Shadows
Subtle shadows beneath the creatures help visually anchor them within the aquarium.
Living Environment
Animated seaweed, coral, starfish, sand, and bubbles add additional movement throughout the scene.
Together, these elements create a complete animated cartoon aquarium rather than a flat wallpaper.
🌴 Three Aquarium Themes
Choose the underwater atmosphere that matches your mood.
Tropical Aquarium
Bright blue water, colorful marine life, and a cheerful tropical atmosphere.
A lively choice for a colorful and energetic desktop.
Deep Sea Aquarium
Dark midnight blues and deeper underwater surroundings create a mysterious and relaxing atmosphere.
Perfect for a calm and immersive desktop.
Koi Pond
Soft green-blue water creates a peaceful environment inspired by a tranquil garden pond.
Perfect for a quiet and relaxing desktop.
Switch themes whenever you want a different aquarium atmosphere.

🖥️ Designed for the Windows Desktop
DeskAquarium is not a full-screen aquarium application.
It is designed specifically as a Windows desktop wallpaper.
The aquarium runs behind your desktop icons so your normal workflow remains intact.
- Desktop icons remain visible
- Files remain clickable
- Applications work normally
- No full-screen window
- No separate aquarium window
- No interruption to your workflow
You can work, study, browse, or simply relax while your aquarium continues swimming behind your icons.
Your Windows desktop remains fully usable — with a living aquarium underneath it.
🌊 More Than a Looping Video
A traditional video wallpaper simply plays a pre-recorded sequence.
DeskAquarium creates its animated aquarium environment in real time.
Fish can move independently. Schools can form and change direction. Different creatures use different movement patterns, while environmental elements continue to animate around them.
Because the creatures aren't simply following a fixed video sequence, the aquarium can feel different from one moment to the next.
Every glance at your desktop can reveal something new.
