Search Fish and Compare Their Details
Search by fish name or alias, then narrow the results by rarity or collection. Open More details for an entry’s additional attributes and conditions, including net requirements, displayed odds, variants and individual income examples.
Keep rarity, collection and mutation separate when comparing entries. A Shiny fish retains its species identity, while Kraken Boss identifies a collection group. For income choices, compare the specific fish’s placement value and its conditions rather than treating an example value as a fixed rate for the whole species.
Rarity Order and Collection Categories
The standard fish rarity order is:
Common → Uncommon → Rare → Epic → Legendary → Mythic → Apex → Demigod → Historic → Monarch → Forbidden → Cosmic → Divine → Abyssal → Empyrean → Supreme → Zenith → Boundless → Eclipse → Genesis → Obsidian → Endless → Absolute → Ancient.
In the Index version with a 171-species counter and 24 standard rarity pages, Common, Uncommon, Rare and Epic each require five species. Endless, Absolute and Ancient also contain five each; the other standard pages contain eight each.
Krakens is a separate collection category, alongside Halloween and Exclusive in the Index with those tabs. Kraken names do not determine their standard rarity: Ink Kraken is Legendary, for example, while Elder Kraken belongs to Historic.
Find Missing Species and Meet Net Requirements
- Select INDEX on the left side of the screen. Choose a rarity category or scroll to its page.
- Find the named entries with question marks. These are species you still need to discover.
- Check the target’s net requirement. If a fish escapes and names a required net, use that requirement to plan your upgrade.
- Select THROW NET, aim with the mouse, then click the water or press C to throw. Let fish enter the net, then select REEL IN.
- Check your catch in Fish Cooler and return to INDEX for the updated species and page progress.
Choose the upgrade that opens your target
Hexbound Net unlocks Forbidden catches; Stardust Net unlocks Cosmic catches. These are useful progression goals when your missing species belong to those rarities. Use the net catalog for prices, purchase prerequisites and unlock requirements.
Specific fish requirements include:
| Target | Required net | Applicable condition |
|---|---|---|
| Striped Bass | Cotton Net | Species detail requirement |
| Abyssal Angler King | Mythril Net | Shiny individual’s escape requirement |
| Frilled Shark | Deepforge Net | Shiny individual’s escape requirement |
| Stormshell Archelon | Celestial Net | Gold individual’s escape requirement |
| Jörmungandr | Ancient Net | Individual’s escape requirement |
| Supernova Puffer | Stardust Net | Individual’s escape requirement |
| Celestial Hippocampus | Halo Net | Shiny individual’s catch requirement |
| Loosejaw Wraith | Hadal Net | Shiny individual’s escape requirement |
| Aurora Seadragon | Aurora Net | Individual’s catch requirement |
| Skyglass Jelly | Aurora Net | Individual’s escape requirement |
| Scepter Swordfish | Imperial Net | Shiny individual’s catch requirement |
| Möbius Eel | Infinity Net | Individual’s catch requirement |
| Fractal Manta | Infinity Net | Individual’s escape requirement |
| Umbra Ray | Umbra Net | Individual’s escape requirement |
Early catches can cross a displayed rarity limit: Prismfin Dragonfish and Frostcrown Seahorse have been caught with Chainlink Net while its interface showed an Epic limit, and Moonveil Jellyfish has been caught in a Common-limit setup. Use an explicit requirement for a fish that escapes when deciding which net to buy.
Choose a method for the gap you want to fill
- Missing species within a rarity: Index Compass lasts 10 minutes and can sometimes change an already-discovered fish into an uncollected species of the same rarity. It is useful when repeated catches are filling entries you already own.
- A target rarity: Deep Current lets you spend charge to call an eligible rarity into your next net. You still need the required net. See Deep Current costs and capture steps.
- A weekly limited fish: Weekly Lure doubles its catch chance for 15 minutes when a weekly limited fish is available. See Pearl Shop tools for tool use.
- More discovery opportunities: Helpers can discover new species. Fisherman can bring in Jaguar Tigershark and Bone Pike; Spear Gun can discover Lantern Eel. Sunfang Shark can return collectible fish such as Nebula Koi and Prismfin Dragonfish.
Claim Page Rewards and First-Rarity Bonuses
Discover every species on a rarity page to unlock its permanent Page Reward. You do not need every mutation of each species to complete that page.
- Open INDEX.
- Select the pending Page Rewards banner to jump to an unclaimed page, or scroll to the completed page.
- Select CLAIM +2% · +1% MUT. The button changes to a check mark with the page’s bonuses.
Each claimed page adds +2% money and +1% mutation chance permanently. Five claimed pages therefore display +10% money and +5% mutation chance.
Three reward types can advance your account:
| Reward | Trigger | Benefit |
|---|---|---|
| Permanent Page Reward | Complete a rarity page and claim it in INDEX | +2% money and +1% mutation chance per page |
| Page-completion reward | Discover the final required species on a page | Can award cash and a timed boost |
| First-rarity reward | Catch your first fish of a rarity | Can trigger a FIRST [RARITY] FISH cash bonus; first Mythic also unlocks a showcase slot |
Page-completion cash depends on progression. For example, Epic completion has awarded $8.18M or $60.81M in different progression states, with 10 minutes of x2 Luck in both cases. These cash amounts are separate from the permanent bonus you claim in INDEX.
A first Mythic catch opens another place to display a fish for income. See showcase placement and fish choices to put that slot to use.
Species Mastery and Individual Fish Values
Open a species in INDEX to inspect its discovered mutations, mastery progress and next Journal reward. Nets, Deep Current, Fisherman and Spear Gun catches count toward mastery. Fused fish do not.
For Striped Bass at Bronze, 17/50, reaching the displayed Silver target requires 33 more qualifying catches. Silver awards a silver stamp in the Journal. That 50-catch target applies to this Striped Bass mastery step.
Compare individual fish for income
Two fish of the same species can have different sizes, mutations and income values. For example, a Stormshell Archelon individual at size 1.05 and 5,811.9 lb had an income reading of $47.13M/s, while another at size 0.97 and 4,517.4 lb had $39.84M/s. Species rarity alone does not select the better individual.
Compare placement income when choosing a fish for a showcase. Catch-result income and placement or showcase income are different readings and can include different boosts. One Prismfin Dragonfish catch displayed $1,512/s, while its later showcase value was $7,560/s; those readings are not a universal conversion formula.
Likewise, an entry’s displayed “1 in” odds should not be treated as your current setup’s independent chance on every catch. Keep the listed odds separate from your active equipment and boosts.
Use the mutation guide to compare mutation effects, the fusion guide to turn duplicates into variants, and the Cooler guide to manage and equip individual fish.
Kraken Collectibles and Boss Encounters
Megalodon is a Demigod collectible fish; Elder Kraken is a Historic collectible fish. Both can be net catches. Megalodon has Normal, Shiny, Gold and Crystal forms, and Elder Kraken can also be Shiny. These fish are distinct from The Megalodon and The Kraken boss encounters.
The separate Kraken Boss collection is marked “limited, beat the Kraken” and has 19 slots in the 171-species Index version. Use the directory’s collection filter to find Kraken entries, including Ink Kraken, Rosequartz Kraken, Bloodfang Kraken and the later named forms.
Ink Kraken can be awarded after defeating The Kraken and is sent to Cooler. A victory does not guarantee a Kraken fish. Once obtained, Ink Kraken can be placed in a showcase for income.
Follow the Kraken boss guide for net placement, participation and reward collection. Use Fish Cooler to manage the collectible afterward.
