Oxygen Tanks are one of the many additions of the Northern Expedition update inFisch, and you’ll have to find this specific item if you want to travel all the locations of the new island.
If you have a boat in your collection, reaching the Northern Expedition Island is pretty easy. You’ll travel to a portal and reach the Northern Summit, which is accessible to everyone. However, you’ll need Oxygen Tanks in order to travel to the more advanced areas. If you don’t have them, your oxygen percentage will consistently drop, and you’ll be unable to make any kind of progress.

In Fisch, there are four types of Oxygen Tanks that you can find and unlock.

How to use Oxygen Tanks in Fisch
The Oxygen Tanks work the same way as your Diving Gear. Once you’ve purchased a tank, you can equip it from your inventory. Since you’ll have to use it frequently in Northern Summit, make sure to place your tank in the taskbar. That way, you won’t need to open the inventory every time you run out of oxygen.
If you’ve just reached theNorthern Summit, you won’t need an Oxygen Tank. However, you’ll need one if you want to access the more advanced locations of the island. Make sure to pay attention to your health while traveling, and equip the tank when required.
