A slow aquarium that keeps growing while you are away. Feed the fish, watch them grow, breed colours you have never seen, and fill the field guide. The fish swim on their own; the light grows on its own.
About A Tank of Light
A Tank of Light is a free browser-based idle aquarium game from alphaBETA DEV (GameStrategists). No download and no in-app purchases; it runs on desktop and mobile. Close the tab and the fish keep swimming — when you come back they have gathered some glimmer for you.
How to play
- Feed: tap the water, feed the fish and watch them grow.
- Breed: pair fish to produce colours you have not seen before.
- Field guide: record every fish you meet, raise or breed.
- Idle: leave for a while and return to glimmer and hatched eggs.
