The new hidden fish are numbers 37 and up in the list below. There are also two new 2,000 pearl fish and a new IAP (that costs a hundred fucking dollars). MOST OF THE HIDDEN FISH UNLOCKS HAVE CHANGED SLIGHTLY, PLEASE READ THE UPDATED INFORMATION!! Thank you u/Kurevin for all the unlocks~!

Abyssrium Pole is live! All hidden fish are found!

Overall, the game is very similar to Abyssrium. You start off with 5,000 vitality and 5 pearls. Use vitality to buy fish and level up your Iceberg, use skills to boost your vitality earnings, rinse and repeat.

1. Harp Seal (Day 2) - although the menu pops up on day 1, you won't actually unlock this 'til day 2

2. Arctic Hare (Day 5)

3. Snow Petrel (Day 9)

4. Arctic Wolf (Day 15)

Not technically an attendance reward, but completing the 9-step tutorial unlocks the Brown Bunny.

Check your "Mailbox" (like the Abyssrium inbox) when it has a red dot on it for rewards!

Level up your Iceberg and your skills. The Iceberg generates per-tap vitality. You get a bonus every 25, 50, 100 etc. Iceberg levels (just like in the Freshwater tank). You can also watch an ad for vitality, buy Blessing of Snow and Vigorous Plankton (DON'T - you get them for free from the Treasure Chest and a few minute trial every day for watching an ad!), and buy instant vitality with pearls (waste of pearls). The Iceberg maxes at 70k levels.

Skills are basically the same as in Abyssrium. Skills now max at level 100.

• Bird Chorus - unlock at Iceberg Level 100 - Auto-Tap 15x/sec and double vitality for 180 seconds at level 1 (this is your "Volcanic Eruption")

• Whales Blessing - unlock at Iceberg Level 300 - Vitality Production x1000 at level 1 (this is your "Delicious Food")

• Moon's Song - unlock at Iceberg Level 500 - Doubles Vitality production for 60 seconds at level 1 (this is, perhaps obviously, your "Song of the Moon")

Also basically the same as in Abyssrium. Artifacts max at level 10.

• Singing Clam Coral - Unlocks at Iceberg Level 600 - permanent auto-taps - 11400 times per minute at max level 10

• Shining Grape Coral - Unlocks at Iceberg Level 800 - permanent vitality boost - 2000% at max level 10

• Resurrection Tower Coral - Unlocks at Iceberg Level 1000 - reduce skill cooldown - by 55% at max level 10

Works exactly like the Coral tab in Abyssrium. Unlock various corals, which generate passive (per-second) vitality as you level up. Corals max at 100k levels.

Normal fish unlocks are listed in game. You get a ~3% bonus for each fish created. Fish now have "types" and "subtypes", e.g. mammal, land-sea, etc. You can see a fish's type and other info by looking at it in Manage Fish.

Hidden fish work slightly differently than in Abyssrium. The game will tell you the unlock for 1 hidden fish at a time. You can "change target" every 24 hours by watching an ad, which will tell you the unlock for a different hidden fish. You also can "change target" by unlocking your current "target" fish. The order in which the game "targets" fish is somewhat random. You can unlock hidden fish even if they aren't your current "target". Hidden Fish don't appear in the Manage Fish list until you unlock them.

In the shop tab, you can buy IAPs, buy creatures with pearls, and receive free in-game currency.

A bird will periodically fly by and drop a treasure chest. Open it by watching an ad. This works just like the Mystery Chest in Abyssrium. The rewards are vitality, pearls, or a trial of Blessing of Snow. Don't waste pearls on Blessing of Snow for the unlocks, because you can get it for free from the chest.

There is improved UI for interacting with the various fish. Clicking on a fish in "Manage Fish" gives you information about the fish's category, sub-category, rarity, and movement type. It also shows the fish's unlock condition and allows you to interact with the fish by deploying or storing it. It also tracks your number of photos of the fish and how many times you've tapped vitality of that fish (useful for tracking unlock progress!) And, you can drag and drop fish to mass-deploy them in the tank!!

You can sort fish by type, e.g. birds, mammals, etc. by clicking on the icon that looks like 4 boxes.

You can also purchase additional tanks in this menu (max of 5), which allows you to create various ecosystems. You can deploy fish on a per-tank basis, which allows you to have custom sets of fish. But, a single fish can only be in 1 tank at a time.

Works exactly like Abyssrium, but you can take "couple photos" with 2 or more animals in it. This is required for some unlocks. To take a couples photo, focus on one animal and wait until it walks/swims/flies close to the other animal, then snap the picture while both are in the viewfinder. If you're successful, you'll get a message in the top left of the screen that the couples photo was taken. The camera also tells you what fish you are looking at (top left corner) when you focus on it.

I can't get the Narwhal! The Longfin Tuna is never close enough to the King Penguin!

Clear out your tank. Fill your tank with as many Longfin Tuna as you can afford. A minimum of 10 of them, more if you can afford them. Create a single King Penguin and stalk him with the camera. Once he dives, take pictures like crazy. If you have enough tuna density, you should get this pretty quickly and your biggest time suck will just be waiting for the penguin to dive.

My game is in Korean! Help!

Navigate through the tutorial by clicking wherever the arrows tell you to click until you reach the main screen. Click on the "Settings" menu (the gear in the top right corner) and click the 3rd full-length button to change your language to one you recognize.

My ads won't work!

Hard close the game and restart it. If this doesn't work, try clearing your phone's cache or resetting your Advertising ID (in your phone's settings).

I can't upgrade corals/icebergs!

Hard close the game and restart.

I didn't get the Harp Seal!

The new day resets 24-ish hours from when you downloaded the game. Just be patient, and you'll get the Harp Seal on your 2nd day of play.

I can't focus on the birds for photos!

Yeah, these are a pain and there's no real trick. My suggestion is to store everything in your tank (Go to Manage Fish -> Reset Tank) and then deploy only the bird you want to take a picture of. Long-press on its icon and then drag it into the deployed fish box to put it back in the tank. Then, there's only one thing other than the Iceberg to focus on in the tank. You can also try tapping on the icon that looks like a compass rose/crosshair in the top right of the screen and locking your screen on a higher-up focus, apparently this helps some people target the birds a bit easier. You can also try just creating a new bird; that automatically locks the camera on whatever animal you just created.

Couples photos are taking forever!

Store everything in your tank (Manage Fish -> Reset Tank) and deploy only the two creatures you need for the photo. They should deploy into the tank near each other, and you can follow one around with the camera until both are within the viewfinder. Alternately, you can make a bunch of Creature #1, store everything in your tank, and then deploy just all of your Creature #1 into the tank. As soon as you do this, go to the fish tab and create a new Creature #2. The new fish should spawn into the tank right where the other critters were deployed and you should be able to get a couple's photo in a few seconds. The couples photos do require the fish to be pretty close to each other and on roughly the same "plane" of depth on the screen. Once you've taken a photo, you can pan around while the screen is frozen to try to set up a better shot for your next attempt.

I have 444442 pearls!

This is just a display bug and might mean you have a crummy internet connection. You don't actually have hundreds of thousands of pearls, sorry to disappoint.

I'm stuck at a wall at F (G, M, O, etc.)!

The "trick" for Pole is similar to the Freshwater Tank in Abyssrium. Because fish aren't worth much in terms of bonuses, your real star of the show is the Iceberg (and the corals in the early levels, especially if you're a more passive player). The basic sequence is Cast Skills -> Buy Iceberg Levels -> Buy Coral Levels -> Cast Skills again. Only buy fish when they're fairly cheap if you're stuck. The free Vitality ad in the Iceberg tab is also fairly useful, especially in early game, so take advantage of that. If you watch the vitality ad while Moon's Song is active, it multiplies your vitality earnings by your Moon's Song multiplier. The "Blessing of Snow" and "Vigorous Plankton" boost is useful but not something you should waste pearls on; you can get it for free by watching an ad for 3 minutes per day or as a reward from the Treasure Chest. Here is a great post by u/JapeCity about how to overcome the vitality walls

I can't unlock the Walrus!

Update your game! The Walrus used to require 13 Sea-Surface type fish; however, only 12 of those are unlockable in the game prior to getting to the Walrus. Unfortunately, this meant the Walrus (and the Humpback Whale, which depends on the Walrus), were unavailable, but this is patched as of Jan 14th 2020.

What counts as a Sea Type / Land-Sea Type / Sea Surface Type?

Each creature lists its Type under its entry in the Manage Fish section. A helpful user created a chart of which creature is which type which you can find by clicking here!

How can I get pearls?

The fastest way to get pearls in the early game is definitely by completing Achievements, though these do eventually max. Your fastest achievements are gonna be your coral level achievements (make sure you level up even your cheap/ineffective corals and you'll get tons of pearls!) and your taking/sharing photo achievements, which can be spammed by taking photos of any old thing and clicking "share" then backing out before a draft has been completed. If you have the Midas Tap skill you can easily spam the "tap x times" achievements, too, by just leaving a stylus on the screen (or a lime or water bottle!), or you can "trap" it on the screen by activating it and then watching an ad without releasing your tap. Put out some Greenland Sharks/Porbeagles with Midas Tap on screen to max the "tap fish bubbles" achievement quickly (they swim below the coralite). You can also get free 20 pearls per 8 hours in the Shop tab by watching an ad - the time between these ads reduces as you level up your Resurrection Tower Coral. And of course open the Treasure Chest as soon as it's dropped, for a 1/3 chance of 10 pearls. (And you can buy them, if you have money. It's more cost effective to buy the fish packages than the pearl-only packages.)

What should I spend pearls on?

Your first pearls should go to leveling up your Whale's Song and Bird's Chorus skill to Level 5, as these are required for an unlock. You can intersperse this with buying levels of the Resurrection Tower Coral, which is the most useful artifact. The Resurrection Tower Coral decreases your skill cooldown (including the time between ad watches to refresh skills) and the time between Free Pearl ads, so it substantially increases your pearl earnings. You'll want to max it out. Then, you'll want to consider saving up your pearls for the 2,000 pearl fish. You need the Blue Arctic Fox for a late-game unlock, so that's your best choice. Finally, dump the rest of your pearls into levels of Moon's Song and Whale's Blessing (they cap at 100 levels), as they're the most effective vitality earners. You can also consider buying and leveling the other two artifacts, but only do that if you like them aesthetically - they grow twice as you level them up and look very pretty, but don't otherwise do much for your gameplay.

I got the Blue Whale - what's this white box in the corner of my screen?

It's a default placeholder for whatever the next "normal" fish will be. The text in Korean says "Next Fish Here".
