You've been there. It’s 3:00 AM. You’re pacing the beach in your pajamas, clutching a golden rod, staring at the pixelated waves of the ocean. You see a shadow. Is it a Coelacanth? Or is it just another Sea Bass? Honestly, the Sea Bass is the "metal fatigue" of the Nintendo 3DS era. It’s everywhere, it’s annoying, and it’s the reason most people give up on their museum collection. But completing the Blathers exhibit isn't just about luck; it's about understanding the internal clock of a game that's now over a decade old. Even in 2026, players are returning to their towns to find weeds, tired villagers, and an empty fish tank.
The animal crossing new leaf fish guide most people use is basically a static list of months. That's fine, but it doesn't tell you the "why" or the "how." It doesn't tell you that the weather isn't just a visual effect—it’s a mechanical gatekeeper. If you aren't paying attention to the barometer in your town, you're going to waste hours catching Horse Mackerel while the rare stuff stays hidden.
The Rain, The Snow, and the Coelacanth Problem
Let’s talk about the big one. The Coelacanth. It’s the crown jewel. In New Leaf, this thing is a absolute diva. It only shows up when it’s raining or snowing. Period. If the sun is out, don’t even bother looking. You’ll find it in the ocean, and it has the largest possible shadow size.
Wait.
Check the shadow carefully. If it’s huge but has a fin? That’s a shark. If it’s huge and doesn't have a fin, it could be a Tuna, an Oarfish, or our elusive "living fossil." The Coelacanth is available all year round, which is a blessing and a curse. It means you don't have to wait for July, but it means you're at the mercy of the RNG weather patterns.
Pro tip: if it's not raining in your town, try visiting a friend's town or going to the Island. However, keep in mind that the Tortimer Island has its own set of rules. The Island is basically a permanent summer. Great for sharks, terrible for Coelacanths. You won't find one there. You need that mainland gloom.
The River Giants: Stringfish and Dorado
Rivers are tricky because the geography of your town matters. Most players forget to check the "Waterfall" or the "River Mouth." The animal crossing new leaf fish guide experience changes completely depending on where you stand.
The Stringfish is a winter nightmare. It only appears from December to February, specifically between 4:00 PM and 9:00 AM. It hangs out at the top of the waterfall. I’ve seen people spend three real-world days fishing the straight parts of the river wondering why they can't find it. You have to climb those cliffs. On the flip side, the Dorado is a summer beast. It’s bright gold, looks amazing in a tank, and only shows up during the day (4:00 AM to 9:00 PM) from June to September.
Tortimer Island: The Bells Are in the Shadows
If you’re playing New Leaf to pay off Tom Nook—and let’s be real, we all are—the mainland is a waste of time. You need the Island. But the Island is a high-stakes environment.

Sharks are the meta here.
The Whale Shark, Saw Shark, Hammerhead, and the Great White.
They all have fins.
See a fin? Heart rate goes up.
But here is what most guides won't tell you: the spawn rate is tied to the number of actors on the screen. If you see a bunch of tiny shadows (Whitespots or Sea Butterflies), scare them away. Run near them. Throw your line and pull it back. You need to clear the "slots" so the game is forced to roll for a rare spawn. It’s a bit of a grind, but it’s the only way to fill a basket with 100,000 Bells worth of fins in twenty minutes.
Don't forget the Whale Shark is technically a "huge" shadow with a fin, but it's much calmer to catch than the Great White. The vibration on the 3DS is a bit of a tell, though it's subtle. You have to react to the sound, not the visual. The "plop" is faster for rare fish. If you rely on your eyes, you're already too late. Close your eyes. Listen for the splash. It sounds weird, but it works.
Small Fish, Big Pride
It’s easy to obsess over the sharks, but what about the Nibble Fish? Or the Neon Tetra? These are "tiny" shadows. The Nibble Fish is a weird one because it's only available from May to September, and only during the late afternoon. It's not worth much, but Blathers will give you a whole speech about how they eat dead skin off feet.
Then there’s the King Salmon. This guy only shows up in September. And only at the River Mouth. That’s the spot where the river meets the ocean. If you’re standing anywhere else, you’re just catching Bass. It’s a tiny window of opportunity, and if you miss that month, you’re waiting a whole year or engaging in the dark art of Time Travel.
The Ethical Dilemma of Time Travel
Speaking of Time Travel, let's be honest. Most of us have done it. You miss the Petaltail Dragonfly (not a fish, I know, but the principle applies) or the Char, and you just... nudge the clock back.

In New Leaf, the consequences for time travel are mostly related to turnips and weeds. But if you're trying to use an animal crossing new leaf fish guide to "speedrun" the museum, you lose the magic. There’s something special about waiting for that rainy June morning to finally hook a Gar. If you jump through time, the seasons lose their flavor. But hey, if you have a job and a life, no one is judging you for setting the clock to 8:00 PM so you can actually catch some evening fish.
Understanding Shadow Sizes (The Visual Cheat Sheet)
Shadows aren't just "small" or "large." There are actually six distinct sizes, plus the finned variety and the "long" shadows like Eels.
- Tiny: Think Goldfish or Popeyed Goldfish. Usually found in the river.
- Small: Crucian Carp or Piranhas.
- Medium: Yellow Perch. The most boring size.
- Large: Black Bass. The bane of your existence.
- Very Large: Barbel Steeds and Carp.
- Huge: This is where the money is. Stringfish, Tuna, Napoleonfish.
The "Long" shadows are unique to Eels and Ribbon Eels. Ribbon Eels are at the Island and they look like thin snakes in the water. They’re worth a decent amount, but they’re tricky to hook because their "hit box" feels a bit narrower.
The Pond: A Forgotten Ecosystem
Don't ignore the ponds. Those tiny circles of water that seem useless? They hold the Koi and the Crawfish. The Koi is a year-round catch and sells for 4,000 Bells. For a beginner, that's a massive boost. The Frog is also pond-only. If you're wondering why your museum is empty despite hours at the river, check the ponds.
Advanced Tactics for the Golden Rod
Once you catch every fish in the game, you get the Golden Rod. It makes the "catch window" longer. Basically, the fish stays on the hook longer before snapping the line. But getting there is the hard part.
The hardest fish to catch isn't the shark. It's the Petaltail Dragonfly (again, bug, but bear with me) or the more elusive seasonal river fish like the Saddled Bichir. The Bichir is only out from 9:00 PM to 4:00 AM in the summer. It’s a "Large" shadow. Most people overlook it because they're busy looking for sharks at the beach.
Semantic Seasonality
- Spring (March - May): Focus on the Loach and the Cherry Salmon.
- Summer (June - August): This is shark season. Also, the Arowana and Arapaima appear in the river. These are huge money makers.
- Autumn (September - November): The Salmon run happens in September. Mitten Crabs appear in the river later on.
- Winter (December - February): It’s Stringfish or bust. Also, look for the Oarfish in the ocean.
Common Mistakes and Misconceptions
One major myth is that holding the "B" button makes fish bite faster. It doesn't. It just makes you run, which scares the fish away. Stop running. Walk.
Another mistake is fishing during the "wrong" hour of a transition. If a fish is available until 4:00 PM, and you start fishing at 3:59 PM, the game might have already swapped the spawn table. Give yourself a buffer.
Also, the "Big Fish Island" is a real thing. If you take a boat trip to the Island, there is a very rare chance you'll land on an island where only large and huge shadows spawn. If you hit this, do not leave until your basket is overflowing. It's a gold mine.
Final Checklist for the Completionist
To truly master the animal crossing new leaf fish guide requirements, you need more than a list. You need a routine.
- Check the weather. Rain means Coelacanth hunt.
- Walk the River Mouth. Don't let the King Salmon escape in September.
- Clean the Island. Scare off the small fries to force the sharks to appear.
- Listen, don't look. The sound of the bite is more reliable than the animation.
- Donate first. Never sell a fish to Re-Tail unless you've checked with Blathers. There is nothing worse than realizing you sold a 15,000 Bell fish that you needed for the collection.
The beauty of New Leaf is the slow burn. It’s a game meant to be played over a year, not a weekend. Each fish you catch is a stamp of time. That Tuna you caught on a cold January night? It’s a memory. That Giant Trevally that took forty tries at the pier? That’s a badge of honor.
Keep your rod ready and your ears open. The museum won't fill itself, and those Sea Bass aren't going to catch themselves (though we all wish they would just disappear).
Next Steps for Your Town:
Start by checking your current month's availability. If it's currently Summer, prioritize the River Mouth and the evening sharks. If it's Winter, focus your energy on the waterfall at night for the Stringfish. Always keep a spare rod in your mail slots or drawers so you don't get caught without one when a rare shadow appears. After you've cleared the water, head over to the Bug Guide to start working on those seasonal beetles, as many of them share the same peak hours as the rare fish.
