Farm a Fish, made by Tetra Games, is an idle fishing game where you place bait, catch fish, mutate them for higher value, and sell them for coins. This guide walks you through starting out, making the most of AFK time, and growing your pond as far as possible.
In shortThe core loop is simple: place bait, collect fish, sell them, and reinvest your coins into better gear.
Everything begins with placing bait in your pond and waiting for fish to arrive. Once you have fish, selling them gives you coins, and those coins let you buy better bait and equipment from the shop.

In shortThe game keeps catching fish and hatching pets while you are away, so logging in regularly to collect is one of the easiest ways to progress.
Farm a Fish is built around the Catch and Hatch system, which runs even when you are not playing. Fish pile up and pets hatch in the background, so every time you log back in there is something to collect.
Tips worth knowing
Log in regularly to collect the fish and coins that have built up while you were gone
Keep pets hatching in the background to push your pond's output higher over time
