Overview

Fish Tank Tycoon is a relaxed fishing game where you catch fish, fill your tank, and let your collection earn money for you. The more you upgrade your rod and bait, the rarer the fish you can pull in.

How the game works

Summary

In short Everything in the game flows from one simple loop: fish, tank, money, upgrade.

You start with a basic rod and some starter bait. Catching fish and placing them in your tank is how money gets generated — the fish do the work for you. That money then goes back into better gear, which opens up rarer catches.

Fishing rod　the tool you use to catch fish; upgrading it increases your fishing power
Bait　determines which fish are attracted; better bait pulls in rarer species
Fish tank　where caught fish live and produce money for you
Money　the resource you spend on all upgrades

Getting started

Step

In short The first thing to do is run the basic loop a few times so you understand where your money is coming from.

When you first load in, your rod and bait are already ready to use.

Pick up your rod cast it and catch whatever fish are available with your starter gear
Place fish in the tank a fish earns money only after it is inside the tank
Watch the money accumulate understanding how your income grows helps you plan your next purchase

Rod and bait upgrades

Tips

In short Both rod and bait can be upgraded with earned money.

Your rod and bait serve different purposes. Spend a bit of time with your current setup first to see what it can catch, then decide which upgrade makes the most sense.

Tips worth knowing

A better rod increases your fishing power
Better bait attracts rarer fish
If you feel stuck, go back to fishing with your current gear and let the money build up before upgrading

Growing your collection

Tips

Rarer fish require stronger gear.

Tips worth knowing

Repeat fishing sessions with your current gear to stockpile money between upgrades
After any upgrade, cast a few times to discover what new fish are now within reach
The whole game can be played without spending real money — time and the earn-upgrade cycle are all you need

Common questions

FAQ

Do I need to spend real money to make progress?

No. The full earn-upgrade cycle works without any real-money purchases. Catching fish, placing them in your tank, and reinvesting the money is the intended way to advance.
