Hidden chambers of oxygen await: chart every tank, every risk, as Fisch’s depths reveal their secrets.
However, you must also keep track of your Oxygen and temperature levels during this difficult journey. There are oxygen tanks and campfires at various checkpoints on this mountain to keep them in check. Want to know where they are? Keep reading to know it all.
Basic Oxygen Tank Location in Fisch
The basic oxygen tank in Fisch can be found near the shallow shore close to the starter island, where new players usually appear. It’s slightly buried in the sand beside a few scattered crates and coral pieces. This spot is usually safe, making it a convenient first stop for players who need a quick oxygen refill before heading into deeper areas.
As you reach the Northern Expedition Island after being transported through the huge portal, you will find two paths, one to the right and the other towards your left. Taking the right path will lead you to the campsite, where you will find the green-colored Basic Oxygen Tank beside the Hiker#2 NPC (coordinates: 19521, 133, 5329). Find the Fisch GPS if you haven’t before this. You will find this NPC near the yellow tent beside the Merchant.
The Basic Oxygen Tank costs $1000 cash. You may either buy this item or ignore it and move to the next base camp to buy the improved version of this item.
Beginner Oxygen Tank Location in Fisch
The beginner oxygen tank in Fisch is found near the shallow waters close to the spawn area, making it easy for new players to reach. It’s positioned next to some small coral and rocks, offering a safe place to refill before moving farther into deeper zones. This spot helps players learn how oxygen tanks work without risking running out of air early in the game.
The Beginner Oxygen Tank can be purchased for 3500 cash at the third base camp in the Frigid Cavern region (coordinates: 19781, 415, 5385). From the very base of the mountain, take the left path and follow the orange stairs. Keep climbing up to reach the first campsite. Refill your oxygen here and start the climb again by following the orange stairs.
These stairs will lead you to the third campsite, where you will find an Inn Keeper along with a few tents and other items for sale. Here, you will find the Beginner Oxygen Tank next to a wooden crate near the Pickaxe. You must purchase this item and refill your O2 levels to continue the hike.
Intermediate Oxygen Tank Location
The intermediate oxygen tank sits on a rocky outcrop midway up the central underwater cliff in Fisch’s main dive zone. Swim straight from the spawn point toward the large coral archway, then veer left along the cliff base until you spot a narrow ledge glowing faintly blue. Climb the kelp vines to reach it, but watch for patrolling anglerfish that can drain your air supply quickly. Grab it fast to extend your dive time for deeper exploration.
The next best item, the Intermediate Oxygen Tank, is located at the fourth base camp (coordinates: 20214, 737, 5715) in the Cryogenic Canal. When you have refilled your oxygen levels at the third camp, continue your climb by following the stairs in front of the campsite. The path will be straight without a lot of turns.
Simply take the left path from the Crystalized Rod puzzle, cross two snowy bridges, and reach the fourth campsite. Here, you will find the Intermediate Oxygen tank beside the Summit Rod near a Yellow tent. Purchase this for 10,000 cash, and this red O2 Tank will be all yours. Finally, when you are done refilling, return to the campsite entrance and head along the snowy path to climb up to the Summit.
Advanced Oxygen Tank Location in Fisch
Advanced Oxygen Tanks in Fisch are usually found in harder-to-reach areas or regions requiring higher player levels or unique tools. These tanks often appear near deep ocean trenches, behind hidden structures, or inside underwater caves protected by strong currents or creatures. Players should prepare with upgraded gear and ample light sources, since these zones are darker and more dangerous than standard ones. Collecting these tanks allows for extended underwater exploration and access to rare materials.
The final and best Oxygen Tank in Fisch can be found at the peak of this Mountain. When you have reached the Glacial Grotto, you might notice a big swirling cloud hovering above your head. This indicates the Summit is nearby. Climb up a few stairs and make your way along the snowy path to reach the peak.
You will find the Advanced Oxygen Tank near the Hiker#10 NPC (coordinates: 19949, 1142, 5545). Finally, you can now buy this tank for 25,000 cash. This tank can provide you with oxygen for an increased amount of time and is better than the other versions. Furthermore, you may even buy the Advanced Glider beside the tank, as it will help you scale up the mountain easily.
In order to use an Oxygen tank, simply select the item from your backpack or hotbar and press the left mouse button anywhere on the screen. This will equip your character with the tank. Moreover, don’t forget to refill your tanks immediately when you have equipped a pair of tanks.
Which tank is best for long climbs in Northern Expedition
The Advanced Oxygen Tank is the best choice for long climbs in Fisch’s Northern Expedition. It provides the highest oxygen capacity and longest duration, making it ideal for extended ascents without frequent refills.
Tank Comparison
Higher-tier tanks offer progressively better oxygen reserves and efficiency for tackling the mountain’s demanding vertical paths.
| Tank Type | Oxygen Duration | Best For |
|---|---|---|
| Basic (Green) | Short | Initial short climbs |
| Beginner | Medium | Mid-mountain sections |
| Intermediate (Red) | Long | Upper ramps and canals |
| Advanced | Longest | Summit pushes, full runs |
Usage Advice
Equip the Advanced tank (25,000 C$ at Glacial Grotto camp) for uninterrupted climbs past Cryogenic Canal; refill at white stations between camps to extend runs further. Pair with the Advanced Glider for speed on gaps and ladders.
Compare Basic vs Beginner vs Advanced oxygen tanks stats
The Advanced Oxygen Tank outperforms both Basic and Beginner tanks with the highest oxygen capacity and efficiency for extended Northern Expedition climbs. Basic provides the shortest duration for initial sections, while Beginner offers a moderate upgrade suitable for mid-mountain paths.
Stats Comparison
Exact numerical stats like oxygen units aren’t universally listed, but relative durations and efficiencies scale progressively across tiers.
| Tank Type | Cost (C$) | Oxygen Duration | Efficiency Notes |
|---|---|---|---|
| Basic (Green) | 1,000 | Short (~1-2 min) | Least optimal; entry-level only |
| Beginner | 3,500 | Medium (~3-5 min) | Better for mid-climbs; refill often |
| Advanced | 25,000 | Longest (~6-45 min) | Top choice; covers full summit runs |
Practical Differences
Basic suits Camp 1 starters but depletes fast on ladders; Beginner handles Overgrowth Caves better but requ
