The fastest way to get an aquarium in Fisch

You get an aquarium in Fisch by catching fish and placing them in a tank you craft or buy. The game does not hand you one at the start — you need to gather materials, craft a basic tank, and then stock it with fish you have caught yourself. Most players build their first aquarium within the first hour of play.

The simplest path is to craft a Basic Aquarium using wood and glass, then catch small fish like Guppies or Minnows to put inside. Once you have a tank placed in your world, you can add more fish to it, and the tank will display them visibly. The aquarium also generates a small amount of in-game currency over time based on the fish inside.

Key Takeaways

  • You craft a Basic Aquarium using 10 wood and 5 glass, which you can gather or buy from other players.
  • Once placed, the aquarium holds up to 10 fish and generates coins based on the rarity and type of fish stored inside.
  • Catching fish with a rod is faster than waiting for them to spawn naturally, and smaller fish are easier to catch when starting out.
  • Upgrading to larger tanks (Medium and Large Aquariums) costs more materials but holds more fish and generates more income.

Gathering materials for your first tank

To craft a Basic Aquarium, you need 10 wood and 5 glass. Wood comes from chopping trees with an axe — any tree in the world will drop wood when you hit it. Glass is made by smelting sand in a furnace, and sand is found on beaches or near water. If you do not have a furnace yet, you can craft one using 20 stone and 5 coal.

If gathering feels slow, you can also buy these materials from other players through the trading system. Check the marketplace to see current prices — sometimes it is faster to earn coins fishing and buy the materials than to gather them yourself. Once you have the materials, open your crafting menu and select Basic Aquarium.

Placing your aquarium and catching fish

After crafting, place the aquarium in your world by selecting it from your inventory and clicking where you want it. The tank will appear as a visible structure that other players can see. Now you need fish to put inside it.

Catch fish using a fishing rod by standing near water and casting your line. Small fish like Guppies, Minnows, and Goldfish are common and straightforward to catch. Rarer fish like Angelfish or Clownfish are harder to find but worth more coins when placed in the tank. Each fish you catch goes into your inventory, and you can then place it into the aquarium by interacting with the tank.

How much money your aquarium generates

An aquarium with fish inside generates coins automatically over time. The amount depends on how many fish are in the tank and their rarity. A Basic Aquarium with 10 common fish might generate 50 to 100 coins per hour, while the same tank filled with rare fish could generate 200 to 300 coins per hour.

The tank generates coins whether you are playing or offline, so it is a way to earn passive income. You collect the coins by interacting with the aquarium. If you want to earn more, you can upgrade to a Medium or Large Aquarium, which hold more fish and generate more total coins.

Upgrading to bigger tanks

A Medium Aquarium holds 20 fish and costs 20 wood and 10 glass to craft. A Large Aquarium holds 30 fish and costs 40 wood and 20 glass. The larger tanks generate more coins per hour because they hold more fish, but they also take longer to fill.

Most players craft a Basic Aquarium first, fill it with common fish, and then upgrade once they have gathered enough materials and caught rarer fish. There is no rush to upgrade — a full Basic Aquarium is profitable enough to fund your next tank.

Common mistakes to avoid

Do not place fish in the aquarium and then remove them when ready — you lose the coins they would have generated. Once a fish is in the tank, leave it there to earn money. Also, do not craft a tank and leave it empty; an empty aquarium generates nothing.

Another mistake is catching only common fish. While they are straightforward to catch, rare fish generate much more income per slot. Spend some time fishing in different areas to find rarer species, and prioritize those for your tank. Finally, do not forget to collect your coins regularly — they accumulate, but you have to manually claim them by interacting with the tank.

Where to find the best fish to catch

Different fish spawn in different water types. Freshwater areas near grass and trees have Guppies and Minnows. Saltwater areas near beaches have Clownfish and Angelfish. Deep water areas have rarer fish like Seahorses and Pufferfish. Explore different biomes to find the fish that work best for your tank.

Fish also spawn more frequently at certain times of day in Fisch, so if you are not catching much, try fishing at a different time. Some players keep multiple fishing rods and rotate between water types to maximize their catch rate.

Frequently Asked Questions

Can I have more than one aquarium?

Yes. You can craft and place multiple aquariums in your world. Many players have several tanks with different types of fish to maximize their total coin generation. Each tank generates coins independently.

What happens if I remove a fish from the aquarium?

The fish goes back into your inventory and stops generating coins. You can place it in a different tank or sell it to another player. Removing fish does not delete them — you just stop earning money from that slot until you put a new fish in.

Do I need a specific tool to catch fish?

You need a fishing rod. You can craft a Basic Fishing Rod using 5 wood and 2 string, or buy one from another player. Better rods make catching rarer fish easier, but any rod works for common fish.

How long does it take to fill an aquarium with rare fish?

It depends on how much you fish and how lucky you are. Common fish take minutes to catch, but rare fish can take hours. Most players mix common and rare fish in their tanks rather than waiting for all rare fish.

Can I sell my aquarium or move it to a different location?

You can remove an aquarium and place it elsewhere, but you cannot sell it to other players. The fish inside stay in the tank when you move it. If you want to get rid of a tank, you have to remove it and let it disappear from your inventory.
