Most players who skip the fish it pet list end up burning hours hatching Commons, since Brown Dog-class hatches sit near a 55% rate and stack only +1 to +5% luck, while the real gains live in the sub-0.2% Secret tier that holds pets like Secret Megalodon and Forgotten Hydras. This breakdown covers every pet from the Tabby Cat quest through the late-game Leviathan, Hydra, and Cat Set drops, the exact luck numbers that move your rod, and which companions are worth rerolling for versus skipping.
What the Fish It Pet List Actually Covers
Pets in Fish It are hatched companions that follow your rod, grant passive buffs, and turn the odds in your favor when hunting the rarer fish in the seven seas. The current Fish It pet list includes more than twenty released companions spanning common hatch odds through the limited Secret tier, with new additions arriving in roughly every monthly patch according to community patch notes. The official Fish It Roblox page confirms that a recent update alone added six pets hatched from the standard Pet Egg, so the roster keeps expanding well beyond what older tier list guides show.
Every pet falls into one of five rarity bands: Common, Uncommon, Rare, Epic, and Legendary, with a sixth Secret band used for event-locked or code-exclusive companions. Rarity dictates not only how often a companion hatches but also the strength of its passive bonuses, which is why players chasing the Forgotten Hydras or the Secret Megalodon spend days rerolling eggs for high-rarity hatchlings. According to the official Fish It game page, the game now advertises over 1,000,000 possible fish variations, and stacking the right pet abilities is the cleanest way to push your luck stat past the soft caps on the late-game islands.
Understanding the pet list matters because each tier multiplies your coin gain, fishing speed, mutation chance, and luck in different ratios. Picking a hatcher without comparing rarity-to-bonus ratios is the most common mistake new Fish It anglers make on the road to unlocking the best rods, and that single decision is what separates a casual day-one roster from a top-1% collection within a season.
Pet Rarity Tiers and Hatch Odds in Fish It
The pet rarity system works on a hidden weight table that the server rolls every time you open a Pet Egg. Higher tiers carry exponentially lower weights, so the same egg can hand you a throwaway Common duck on one open and a Legendary companion on the next. The table below breaks down the current five-tier breakdown, the approximate hatch rate, and the kind of passive ability you can expect at each band.
| Rarity Tier | Approx. Hatch Rate | Ability Strength | Example Companions |
|---|---|---|---|
| Common | ~55% | +1 to +5% luck | Brown Dog, Orange Tabby Cat |
| Uncommon | ~25% | +5 to +10% luck, small coin boost | Grey Cat, Yellow Bird |
| Rare | ~12% | +10 to +18% luck, mutation rate up | Blue Tang, Turtle |
| Epic | ~6% | +18 to +28% luck, faster cast | Orca, Phoenix |
| Legendary | ~1.8% | +28% to +40% luck, sell multiplier, XP boost | Leviathan, Hydra |
| Secret | <0.2% | Unique stacking buff, often event-locked | Shadow Serpent, 8-Bit Cat |
These percentages are community estimates drawn from player-reported egg-opening logs on the Fish Atelier group, not hard numbers printed in the UI. The group, which has roughly 3.77 million members according to its verified Roblox page, is the most reliable place to cross-check current hatch odds after each patch because the developers post event windows and code drops there in real time.
How Rarity Affects Your Fishing Session
A Legendary pet does not simply hand you more fish; it shifts the underlying probability curve. A +35% luck bonus from a top-tier hydra is applied multiplicatively against your rod's base luck, the island's ambient luck, and any active luck potion, which means the effective gain compounds dramatically at the higher end. That is why Epic and Legendary companions are non-negotiable for any player chasing Secret fish on the Arcadia limited island or the Withering Core expansion zones.
The Tabby Cat, Orange Cat, and How the Pet Quest Unlocks Them
The Tabby Cat is the mascot companion most new players meet first, and the Fish It pet quest chain that unlocks it is a soft tutorial for the entire pet system. Orange and Grey tabby variants both come from the same questline, so the choice at the end of the chain determines which color you keep.
The unlock flow runs like this:
-
Step 1: Reach Player Level 5 by catching any combination of fish on the starter island. Leveling up unlocks the quest NPC Mochi the Catkeeper, who appears near the spawn dock.
-
Step 2: Catch 10 Common fish in a single session to trigger the quest prompt. The NPC rewards you with one free Pet Egg and 250 Coins.
-
Step 3: Open the egg on the spot. Each guaranteed first-egg hatch is at least Uncommon, so the chain reliably hands you either a Grey Cat or an Orange Tabby.
-
Step 4: Return to Mochi, who buffs whichever cat you hatched with a small permanent luck bonus and unlocks the Cat Family sub-quests, which then chain into the rarer feline pets later.
Players who want the orange variant specifically should reroll the egg through the Pet Reroll potion obtained from codes. The orange coat carries a slightly higher coin-gain bonus than the grey, while the grey leans into mutation chance, so the choice is not purely cosmetic once you factor in pet abilities. Community testing reported on YouTube walkthroughs such as the noob-to-master progression video shows that rerolling into the orange variant early is the most efficient way to start scaling coin income before unlocking the better farming islands.
Why the Tabby Matters Even for Veterans
Even experienced Fish It players keep at least one Tabby Cat in their active pet slot because the coin-gain passive stacks with other companions. Two cats in your party give you the Double Cat hidden set bonus, which adds an extra 4% sell multiplier on top of the individual passive. That bonus is the cheapest way to push coin income past the 100,000-per-catch threshold without grinding for a Legendary hydra.
Pet Abilities, Buffs, and Which Stats Actually Matter
Pet abilities in Fish It fall into seven core passive categories, and the most valuable companions stack two or three of these at once. When you read a pet card in the menu, the description lists a primary buff, a secondary effect, and a hidden tertiary that activates only above certain thresholds. The table below lists every ability type and the pet archetypes that typically carry it.
| Ability Type | Effect | Best Pet Archetype | Stackable |
|---|---|---|---|
| Luck Boost | +1 to +40% catch rarity odds | Cats, Birds, Phoenix | Yes |
| Coin Boost | +2 to +25% sell value | Orca, Turtle, Orange Tabby | Yes |
| Mutation Rate | +1 to +12% mutation chance on catch | Hydra, Phoenix, Tang | Yes |
| Cast Speed | Reduces mini-game duration by 5 to 30% | Orca, Yellow Bird | Yes |
| XP Boost | +3 to +20% player XP per catch | Dog, Turtle, Cat | Yes |
| Sell Multiplier | Flat multiplier added to final sale | Orca, Legendary pets | Limited |
| Event Buff | Doubles catch rate during events | Limited pets, Secret tier | Event-locked |
Pet rarity matters, but ability type matters more for the specific grind you are running. If you are farming Coins to upgrade your rod, coin-boost and sell-multiplier pets are the better long-term pick, even at Uncommon tier. If you are hunting the Forgotten Hydras or the new 8-Bit mutation, mutation rate and luck boost are non-negotiable. A full breakdown of how each pet ability interacts with specific fish hunts is covered in the Fish It mutation tier list guide, which lays out the side-by-side stat math in more depth.
Hidden Set Bonuses and Stacking Rules
Fish It rewards players who collect pet families rather than just rarities. Completing a family of three (for example, all three cats, all three birds) unlocks a hidden set bonus that stacks with the individual passives. The stacking rules cap at three set bonuses at once, so chasing every set is a long-term project, but the Leviathan Set, the Hydra Set, and the Cat Set are the three most common endgame loadouts for serious Fish It players.
How to Hatch, Reroll, and Equip Pets Efficiently
Hatching pets is straightforward but expensive if you do not manage your coin flow. Each Pet Egg costs 25,000 Coins at the in-game pet shop, and rerolls cost another 15,000 Coins per attempt plus a Pet Reroll Potion obtained from limited codes. The beginner-to-advanced tips video embedded in the tips and tricks walkthrough walks through the same reroll math most high-level players use, and the math shows that saving eggs for double-xp weekends is the cheapest way to fill out your roster.
| Hatch Source | Cost | Best Use Case | Notes |
|---|---|---|---|
| Pet Egg (shop) | 25,000 Coins | Bulk farming, filler pets | Always Common–Rare odds |
| Premium Pet Egg | 50,000 Coins | Targeting Uncommon+ rolls | Higher Legendary chance |
| Quest Reward Egg | Free | First Tabby unlock, low reroll cost | Guaranteed Uncommon+ |
| Event Egg | 5,000–10,000 Coins | Time-limited Secret-tier rolls | Only during event windows |
| Code Reward Egg | Free (code only) | Free reroll material | See codes page for active list |
Equip your pets from the Pet Menu by clicking the paw icon in the top-left of the HUD. The menu shows your current party of up to three pets, their passives, and the active set bonuses. Equipping a higher-rarity pet overwrites the slot, but you keep the old pet in your inventory for set-completion purposes, so never sell a duplicate just because you found a better one. A full equip-and-buff walkthrough is in the Fish It pet equip guide, which explains slot priority, party swaps, and the exact UI flow for newer players.
Pet Hatching Mistakes That Burn Through Coins
Three mistakes drain coins faster than anything else in the pet loop. The first is rerolling on a low-coin account; you should always hold at least 100,000 Coins in reserve before touching the reroll screen because the pity system caps at the 20th attempt, and most players hit their best pet between rolls 12 and 18. The second mistake is selling Common pets early; even a Common Brown Dog adds a small XP boost that compounds across thousands of catches. The third is ignoring event windows: during limited-time Arcadia or 8-Bit events, the egg pool shifts, and you can hatch Secret-tier pets at normal-rarity odds if you time your pulls correctly.
Late-Game Pets Worth Chasing and the Ones to Skip
The current pet meta favors three archetypes: cats for coin gain, hydras for luck and mutation, and birds for cast speed. Anything outside these three is mostly a collection project, not a power upgrade, so if you are short on coins, ignore the cosmetic-heavy pets and focus your rerolls on the ones that move the numbers.
| Pet Name | Rarity | Primary Buff | Late-Game Verdict |
|---|---|---|---|
| Orange Tabby Cat | Common | +5% coin gain | Keep one always, do not reroll |
| Grey Cat | Uncommon | +8% mutation chance | Solid mid-game pet |
| Blue Tang | Rare | +12% luck | Pre-Legendary bridge pet |
| Orca | Epic | +20% cast speed, +10% sell | Top-tier farming pet |
| Phoenix | Epic | +25% mutation, +12% luck | Must-have for Hydra hunts |
| Leviathan | Legendary | +35% luck, sell multiplier | Endgame anchor pet |
| Hydra | Legendary | +30% luck, mutation, XP | Best all-rounder |
| 8-Bit Cat | Secret | Doubles mutation odds | Limited event, chase only during window |
| Shadow Serpent | Secret | +40% luck on night maps | Code-locked, check active codes |
For a deeper dive on how these pets fit into the broader mythic and legendary fish hunt loop, the rare fish tier list guide pairs cleanly with this article because the pet passives described above are what make the rare fish hunts actually solvable in a reasonable time window.
How the Pet Roster Ties Into the Pet Egg Economy
Pet Eggs remain the only practical way to fill out the late-game roster because quests, codes, and event drops only cover the early tiers. The current Pet Egg economy, confirmed in the official store description on Roblox, added six new pets in the latest patch alone, so the gap between a starter roster and a complete collection is wider than older guides show. If you want the full pet-by-pet breakdown with every hatch method, the Fish It all pets guide goes into per-companion detail and is the best next read once you have the rarity and ability framework down.
Frequently Asked Questions
How do I get the Tabby Cat in Fish It?
The Tabby Cat is unlocked by reaching Player Level 5, talking to the catkeeper NPC Mochi at the starter dock, and completing the 10-fish catch quest. The reward egg you receive guarantees either the Orange Tabby or the Grey Cat on first hatch, and rerolling with a Pet Reroll Potion lets you swap between the two variants at any time.
What is the rarest pet in the Fish It pet list?
The Legendary Hydra and the Leviathan sit at the top of the standard pet list at roughly 1.8% hatch odds each, while the Shadow Serpent and the 8-Bit Cat are the rarest Secret-tier companions because they only appear during limited events or through exclusive code drops, with community-reported odds below 0.2%.
Do pet abilities stack if I equip more than one pet?
Yes, up to three active pet passives stack additively for most buffs and multiplicatively for luck and sell multiplier. Set bonuses from full pet families also stack on top, with a hard cap of three set bonuses active at once to keep the math from breaking late-game balance.
Can I sell pets I do not want?
Yes, every pet in your inventory can be sold for a small coin return based on rarity, but selling Common and Uncommon pets is generally a long-term loss because their XP and coin passives add up over thousands of catches. Most experienced players only sell duplicate Legendaries they no longer need for set completion.
How often does Fish It add new pets to the list?
Based on community patch tracking and Fish Atelier group posts, new pets arrive in roughly every major update, which has been running at a one-to-two-month cadence through 2026. The most recent update added six pets from a single Pet Egg, so the roster is expanding faster than the older tier list guides show.
