Harpoon a Fish Beginner Guide: First Catch, Pets, and Deeper Dives

A practical Harpoon a Fish beginner guide covering your first catch, reel timing, aquarium pets, Mukbang table weight, and smarter early spending.

Why the First Dive Decides Everything

Most new players lose their opening fish for one reason: they stop reeling too early. This Harpoon a Fish beginner guide exists to break that habit before it becomes permanent, because the first ten minutes teach the exact loop the rest of the game is built on. Treat this Harpoon a Fish beginner guide as a checklist rather than a lore dump — one clean catch, one pet in the aquarium, one deeper dive — and you will understand more than most players do after an hour of frantic clicking.

The game splits aiming and catching into two separate skills. A harpoon that connects only starts the attempt. The fish is not yours until the reel prompt finishes, and that single distinction is where most early frustration comes from.

Stage	What you do	What it actually means
Aim	Line up the marked target	You have chosen a fish
Fire	Click to launch the harpoon	The attempt has begun, not ended
Reel	Follow the timed prompt to completion	The catch is landed
Return	Surface and bank the result	Progress is recorded

If you take one thing from this Harpoon a Fish beginner guide, make it the third row. Hitting the target is a start signal, not a trophy.

Finish the Marked Catch Before Chasing a Monster

The tutorial gives you an arrow and a specific fish. Follow both. Swim out, aim at the highlighted target, fire using the demonstrated PC controls, and then put all your attention on the reel prompt until the catch is confirmed. Only after that should you start thinking about what you want to hunt next.

New players love to skip ahead to the biggest silhouette on screen. That adds a collection goal on top of an input sequence you have not learned yet, and it usually ends with an empty bag and a vague sense that the game feels clunky. It is not clunky — it is two systems, and you skipped one.

Small catches are not wasted catches. Community reports consistently describe early shrimp-style grabs as a perfectly respectable first result, because the real reward is muscle memory: where the harpoon travels, how the hit registers, and what a successful reel looks like on screen.

Opening target	Should you take it?	Why
The marked tutorial fish	Yes, first	Teaches the full fire-then-reel sequence
A small nearby catch	Yes, fine	Same lesson, low pressure
A mid-sized fish	Later	Adds difficulty before the basics are automatic
The largest visible creature	Not yet	Turns a tutorial into a challenge run

A simple rule for your first three catches

Land three catches in a row without abandoning a reel. If you can do that, you have earned the right to experiment. If you cannot, stay on the marked targets a little longer — the game is not going anywhere.

Bring the Catch Back Into the Island Loop

The dive is only half the session. On PC, the tutorial uses Space to return to the surface, and the game then pushes you back into island tasks rather than letting you idle in the water. Follow those arrows.

The first island stop is the aquarium. Caught fish can become aquarium pets, and the developer explicitly ties the aquarium to growing your new catch. That reframes every fish you pull out of the water: it is not just a number in a bag, it is a candidate pet with a growth path attached.

The next stop is a Mukbang table purchase and an eating interaction. Buy the table when the task appears, sit down, and complete the eating step. This is not filler content — it introduces the second progression axis in the game.

Task	Action	Useful result
First catch	Aim, fire, and time the reel	A landed fish instead of a near miss
First pet	Return to the island and place the catch in the aquarium	A pet you can grow
Deeper reach	Buy the Mukbang table and complete the eating step	Character-weight progression

Why weight matters more than you think

Weight affects how deep your character can sink. A heavier character reaches water that a lighter one simply cannot. That means the fish available to you change as your character develops, independent of how good your aim is.

This is the part of the game that catches people off guard. They grind accuracy, get very good at hitting targets, and then wonder why the good fish are always out of reach. Accuracy and depth are different problems with different solutions.

Progress type	What improves it	What it unlocks
Accuracy	Practice with the fire-then-reel sequence	Fewer escaped catches
Reach	Eating and weight progression	New depths and new species
Collection	Aquarium placement and growth	Pets and long-term goals
Loadout	Equipment slots for harpoons you own	More tools available per dive

Give Your First Earnings One Job

Opening money is tempting to spend on whatever button looks most exciting. Resist that. In player experience, the cleanest early purchase is the one the tutorial is actively asking for, because finishing the guided loop unlocks systems that make every later purchase more useful.

The Mukbang table is a good example. It looks like a cosmetic side purchase until you realize it is the gateway to eating, weight, and depth. Equipment slots work the same way later — they let you field more of the harpoons you already own, which quietly multiplies the value of everything in your inventory.

Community reports also mention a code list and Playtime Rewards available while you are on the island. These reward XP, potions, and — in the creator code reward — Ruby Keys. Keep those names straight in your head:

Reward type	Where it fits	Beginner caution
XP	General leveling progress	Do not confuse it with money
Potions	Consumable items in your inventory	Check the menu before assuming a use
Ruby Keys	Key-type currency tied to locked content	Do not assume every crate is now openable

A reward only helps when you know which menu consumes it. Claiming something and immediately forgetting where it went is the most common early mistake reported by new players.

Choose a Second-Session Goal You Can Actually Finish

Once you have landed a catch and placed a pet, pick exactly one reason for your next dive. Not five. One.

Good candidates include the fish a bait recipe is asking for, a missing entry in your index, or any catch from water your character can now reach after gaining weight. A specific target turns a wandering dive into a productive one, and it gives you a clear stopping point so you do not burn out in a single sitting.

Goal type	Best for	Why it works
Bait recipe fish	Players who like crafting	Gives the catch an immediate use
Missing index entry	Completionists	Small, measurable progress each dive
Newly reachable depth	Players who just gained weight	Tests your new range while it is fresh
Aquarium pet upgrade	Players who enjoy the pet loop	Turns a fish into a long-term project

Notice what is missing from that table: "catch everything." Vague goals are why players bounce between objectives, feel busy, and end the session with nothing to show for it.

Mistakes worth avoiding in week one

Firing and then releasing the reel prompt early — the single biggest cause of lost fish.
Chasing a large creature before the marked tutorial catch is complete.
Skipping the Mukbang table task and then wondering why deeper water is unreachable.
Spending opening money on optional items while a guided task sits unfinished.
Hoarding rewards without checking which menu uses them.

If you want to verify platform availability or check for an official store listing before you commit, a quick search for Harpoon a Fish on Steam is a reasonable starting point, though the game's own tutorial remains the only source that matters for controls.

The Beginner Loop in One Screen

Here is the whole opening compressed. Read it once, then go play.

Minute	Focus	Success looks like
1	Follow the arrow into the water	You are aimed at the marked fish
2	Fire, then reel to completion	A confirmed catch, not a hit
3	Surface and return to the island	You are back in the task loop
4	Place the catch in the aquarium	A pet exists in your collection
5	Buy the Mukbang table and eat	Weight progression begins
6+	Pick one specific next target	A dive with a purpose

That is the entire Harpoon a Fish beginner guide in table form. Everything after this point is refinement: better aim, deeper water, more harpoons in your slots, and a collection that grows one deliberate catch at a time.

FAQ

How long should my first session in Harpoon a Fish last?

Long enough to finish the guided tasks and place your first pet. Do not measure it in minutes — measure it in completed steps. If the aquarium task and the Mukbang table task are both done, you can stop with a clean save state and a clear next goal.

Why do my harpoons keep missing even when I aim well?

In most cases the shot is landing and the reel is failing. Following this Harpoon a Fish beginner guide's core rule — fire starts the attempt, reeling finishes it — fixes the majority of "misses" that are actually abandoned catches.

Can my first catch really become a pet?

Yes. Returning to the island and placing your catch in the aquarium is one of the earliest guided tasks, and the aquarium is specifically designed around growing your new catch. Even a modest shrimp-style first catch is worth placing.

Why can't I reach deeper water yet?

Depth is tied to character weight, and weight is tied to the eating progression introduced by the Mukbang table. Improve your reach by completing that task line, not by swimming harder at the same depth. Once your character develops, the fish you can reach changes with it.
