Fish Tycoon 2 challenges players to breed, nurture, and sell fish, discover rare and magical species, upgrade equipment and environments, and manage a storefront. This guide gives you clear strategies, tips, and optimizations to accelerate your progress in the game.
What Players Commonly Get Wrong (and How to Avoid It)
Before diving in, here are mistakes many players make that slow them down:
- Spending Gems to buy unnecessary stuffs.
- Investing too early in vanity upgrades (decorations, ornaments) rather than income-boosting ones.
- Hatching Uncommon and Rare Eggs.
- Letting tanks sit idle (not breeding or selling efficiently).
- Neglecting environment / food / tech research which unlocks rarer fish and more revenue.
- Pricing fish too low or too high, missing out on profits or having low turnover.
Core Strategies to Speed Up Progress
Here are steps and tactics that can significantly shorten the grind.
Yow will start your journey with 500 coin and 100 diamond. Using them properly will led you to success faster, otherwise you will ruin your career.
After breeding the common eggs we will have 7 common baby fish. Using INSTAGROW Raise them to Adulthood. Normally you will get your 1st Magical fish of Nutrition among them.
If you do not get any magical fish or incase my mistake you sold the fish you have to breed some fish to get it back. However our goal is to earn as much money possible and upgrade everything. But we have to upgrade everything in a systemic way. Follow the steps ton Grind Many coins in Fish Tycoon 2.
1. Prioritize Research & Upgrades That Scale Your Earnings
- Environment & Food Upgrades: Our main goal will be Environment Research leveling up.
You will find it on Supplies > Research
Level up only Environment Research. You will have one free upgrade and next level is 200 coin. Using 200 coin Upgrade it. It helps fish to survive. Do not spend money on Food & Advertisement. We will upgrade them Later.
2. Efficient Breeding — Use Known Combos & Charts
Main mechanism of this game it to breed fish, raise them and sell. So breed as many fish as you can, raise them and sell. You can earn money buy selling these fish. But be careful, do not breed any rare fish. Without upgrading Environment Research they all will be dead.
3. Use Magic Fish Strategically
Common fish sells at a cheaper price. Where a common fish sells for $4-$7 , A Magical fish sells for $50-$350. so Our main priority is to breed another Magical Fish of Nutrition. To get another try this following best breeding combos in Fish Tycoon 2.
Breed common fish until you get one CRIMSON TIGERFISH, If you do not get one sell some fishes and buy common eggs and find CANARY SHARK and SPINED BETA. After having them breed for your 2nd Magical Fish of Nutrition.
There are also some other combo to get this Magical Fish.
Magic fish of nutrition + Striped flash fish
Daffodil Beta + Spined Shark
Crimson Tigerfish + Royal Tigerfish
After having two Magical Fish of Nutrition sell every other fishes and breed Magical Fish only. Now in two tanks you can have 21 + 21 = 42 Fishes. Keep 14 fish for breading and sell the rest. Set the Magical Fish price to $50, In this way selling 28 fishes you can earn $1400 every time.
4. Task & Goals

5. Increase Baby Fish
From the shop buy PLANT OF FERTILITY, and it will double the baby Production.
More tank can hold more fish, results more money. Buy additional Tank and double your production.
6. Use Time & Game Speed to Your Advantage
- The game runs in real time — take advantage of idle periods (e.g. overnight) by setting up as much as possible beforehand (e.g. breeding, feeding, having tanks full).
- Repair the fountain and spend your time on Sell section. you will earn plenty of coin.
7. Optimal Pricing & Turnover
- When fish mature, price them carefully. If price is too high, they may sit unsold and block capacity; too low, you leave money on the table.
- Monitor demand: if many fish are selling too fast, raise the price upto 10%; if nothing’s selling, lower price.
- Sometimes it’s better to sell lower-earning fish to free capacity and resources for rarer, more profitable fish.
8. Manage Fish Health & Feeding
After grinding Magical fish of Nutrition hope you will have enough money. Using them upgrade your Environment research to Maximum Level. Now we can have rare fish on our tank, They won’t die anymore. Now we are ready to earn 7x more money.
9. Breeding the Ultimate Fish
GOLDEN GUPPY OF ISOLA is the final magical fish of this game. You can sell it for $350, which is far more than other fishes. After maxing Environment Research, we finally are able to have rare fishes in our tank. So now we will breed the GOLDEN GUPPY OF ISOLA. There are a lot of breeding combination for this fish.but so far the easiest one is CRIMSON GOLDSHARK + MAGIC FISH OF NUTRITION. Since we have MAGIC FISH OF NUTRITION, we will need a CRIMSON GOLDSHARK. Buy Uncommon eggs from the shop and breed them. After breeding some of the eggs we will have the CRIMSON GOLDSHARK. Now we are ready to breed the ultimate GOLDEN GUPPY OF ISOLA
Incase you are are unable to find CRIMSON GOLDSHARK here are some other combination to breed GOLDEN GUPPY OF ISOLA

Thurs you can make $100k coin everyday easily in legal way. Now you can upgrade rest of the reasearch , Buy another sales tank, Temperature regulator, Cleaning Snail, Plants and so on.
Advanced Tips & Shortcuts
Once you have basic strategies down, these can help you leap ahead.
- Plan Magic Fish acquisition order: Some magical fishes give you multiplier effects or reductions in costs which help make subsequent magic fish easier to get or use. Acquire those which grant economy or speed first (like Nutrition, Maturity) before ones that give more exotic effects.
- Maintain a balanced species catalog: Discovering new species sometimes unlocks bonuses, additional charts, or achieves collections. Having a wider set of fish helps with breeding combos and unlocking rarer lines.
- Limit time wasted: Don’t let tanks stall. Even if breeding isn’t perfect, having fish growing and being sold constantly is better than having idle capacity.
- Watch for game mechanics and hidden bonuses: Hidden combos, special plants, etc. Fandom wikis and community guides often contain breeding combinations, magic fish stats, tips for fish effect synergies.
Progressing faster in Fish Tycoon 2 is about balancing short-term profits (selling fish, earning income) with long-term growth (research, environment, unlocking rarer fish). Focus early on breeding profitable lines, smart upgrades, taking advantage of magic fishes, and efficient resource management.
If you follow these strategies, you’ll:
- discover more fish species sooner,
- generate more revenue faster,
- reduce downtime from sickness or idle tanks, and
- unlock the more advanced features much sooner.
