A cozy idle game about fish. They dig, you hatch eggs, and your reef grows even while you are away.
Watch the trailer



Up to six of your fish dig through the sand mounds of your reef. Under them lie coins, eggs and old finds.
Mound by mound you go deeper: through 10+ zones, from the Sunlit Shallows down to the Abyss, past mini bosses and zone bosses.

Hatch your eggs in the Hatchery and meet a new fish. Many are Common, a few are Mythic, and now and then one comes out Shiny.
The exact odds are on the screen before you hatch. And every season has its own rare seasonal fish.




Fill your Fish-Dex, once with the normal fish and once with the Shinies.
Bond two fish of a kind to make one stronger, and put your favourites in the aquarium, where they swim through your reef.




In Explore a team of three follows the treasure map through eight areas, from the Sunny Shallows to the Ancient Ocean Temple. The fish fight on their own, you pick the team.
Each area has ten stages, and the last one is a boss. Every win brings coins, and every boss opens a new area.




In the Reef League your team of three takes on other teams. Every win brings rating, and with it you climb through six leagues, from Sandy up to Leviathan.
On the way up you collect eggs, shells and coins. And with every new season the climb begins again.




Set lighthouses, corals, old amphorae and treasure chests around your sand mounds. Many decorations bring a small bonus too.
Visit the reefs of your Steam friends and lend each other a fish.




Close the game and your fish keep digging for a while. When you come back, coins and eggs are waiting.
An upgrade tree with 277 nodes, daily and weekly goals and 69 achievements give you something to aim for. And with the Great Tide you start the dive again from the top, with pearls for lasting blessings.

FIH is free to play, and there is not a single ad in it.

Every fish and every Shiny can be had without paying anything.

You see the exact chances before you hatch an egg.
There is a shop for players who want to save time or support the game. Nothing in it is needed to get every fish.

FIH comes to Steam for Windows, free to play. The first egg is already waiting for you.
