Focus Fish Tank

Stay focused or your fish will suffer. A virtual fish tank that reacts to your browsing habits.

--- Your fish are watching. Don't let them down. Focus Fish Tank is a productivity Chrome extension that turns your browsing habits into a living aquarium. Stay on task and your fish grow, thrive, and glow with health. Get distracted and they fade, sicken, and eventually die. It's the accountability buddy you never knew you needed. --- 🐟 A Tank That Reacts to You Your focus score rises every few seconds you spend on productive sites — and drops the moment you drift to social media, streaming, or anything on your blocklist. The entire tank reflects your state: clear water and shimmering light rays when you're focused, murky green water and creeping mold when you're not. --- 🪙 Earn Coins. Build Your World. Every moment of focus earns coins. Spend them in the in-popup shop: - 7 unique fish species — Classic, Tetra, Puffer, Angelfish, Tang, seahorse, and the rare Dragonfish - 5 decorations — Sea Kelp, Fan Coral, Branch Coral, Anemone, and a gilded Treasure Chest - 7 tank backgrounds — Open Ocean, Twilight Zone, Kelp Forest, Coral Reef, The Abyss, Golden Reef, and Bioluminescent Every fish you buy arrives as a tiny fry and grows through juvenile to adult as your tank stays healthy. --- ⚙ Fully Customizable - Set your own distracting sites blocklist - Configure work hours so your score only tracks when you're actually meant to be working - Rearrange decorations by dragging them around the tank - Choose from 5 UI color themes — Ocean, Midnight, Coral, Forest, or Classic - Claim a daily coin bonus every day at midnight --- 🐠 Your Fish Have Lives Fish aren't just decorations. They have HP, grow over time, react to tank health with expressions and color, and can be released back to the ocean from the Settings page. Fish that don't survive are remembered in the Graveyard. --- Privacy: Focus Fish Tank works entirely on-device. No data ever leaves your browser. No accounts, no servers, no tracking. ---
