About Build Your Aquarium
Build Your Aquarium is a management game with a fishing loop attached. You dive to catch fish, bring them back to stock your tanks, and serve customers who come to see them — then reinvest the takings into deeper diving, bigger tanks and rarer species.
The two halves feed each other: better equipment reaches deeper water, deeper water holds rarer fish, and rarer fish bring more customers. It's an idle game with an unusually pleasant theme.

- Reinvest immediately rather than saving up.
Build Your Aquarium — questions
How do you get rare fish?
Upgrade your diving equipment to reach deeper water. Depth is what gates the rarer species, and those are what bring in the higher-paying customers.
Is it an idle game?
Largely — production continues while you manage other parts of the aquarium, and the loop is built around reinvestment.
Does it work on a phone?
Yes — slide and tap. Nothing to install.
