Deep Fishing Fish Rarity Tier List: Common to Secret Order

Deep Fishing's rarity order runs Common, Legendary, Mythical, Secret. See what each tier means for sell value, first-catch badges, and progression — and why mutations are a modifier, not a tier.

Quick answer

Deep Fishing's published rarity ladder runs, bottom to top: Common, then Legendary, then Mythical, then Secret. Secret is the top of the published rarity names and has its own first-catch badge. Everything that is not Legendary, Mythical, or Secret counts as Common, and mutations are a modifier on whatever rank you already caught — not an extra rung on this ladder.

Legendary is the first named rank most players actually see; Mythical sits above it and under Secret.
Caveat: gameplay footage shows in-water labels such as 'uncommon', 'rare', and 'epic' that the published ladder does not list — the ladder folds everything below Legendary into Common.
Species-to-tier assignments and an official per-tier price table are not published; fish and sale examples in this guide come from gameplay footage, not fixed game data.

Common: the baseline economy

Common is the unnamed bulk of the ocean — anything that is not Legendary, Mythical, or Secret lands here. Commons pay for Strength and fill the 50 / 250 / 1,000 catch badges; they are the economy rather than a failure state, "paying the bills" for the whole ladder. The recommended treatment is to sell Commons unless a mutation is sitting on one and the First Mutation badge or a wanted variant is still missing. Do not build a museum of Commons while the Strength bar is empty.

Legendary and Mythical

Legendary is the first named rank most players actually see. The First Legendary badge marks the moment the rod has left the purely Common economy and proves that farther water works. After the badge, Legendary fish are the mid-game coin engine: they sell better than Commons, show up more often than Mythical or Secret, and fund the next Strength buys.

Mythical sits under Secret and above Legendary. First Mythical is a real badge, so the game treats the first one as a milestone rather than vendor trash — Mythical hunts are the main reason to keep pushing Strength instead of parking in a comfortable mid ring. A Mythical with a mutation is a collector piece; a Mythical without one is still a high sell. Gameplay footage shows both labels appearing on catches.

Secret: the top published rank

Secret is the top of the published rarity names and carries its own first-catch badge, which is marked rare for a reason. Because a Secret is a session event rather than another Common, pause Auto Sell when a silhouette or label looks wrong in a good way and confirm the rank before the inventory clears. Secret hunting is a late-loop activity: distance first, luck second — standing in the starter ring with a luck pass will not reliably farm one.

Current scarcity figures are inconsistent snapshots. The Roblox game-page statistics list First Secret at a 28.9% win rate with 47,686 awards, while a wiki page states only about 1.4 percent of players hold the badge. These may measure different bases or different snapshot dates, so do not merge or average them — check the badge's award count in-game or on the Roblox game page for the current figure.

Mutations are a modifier, not a rarity tier

Mutations are not a fourth named rarity above Secret and not a replacement for Legendary; they modify a catch that was already made. A mutated Common is still not a Secret. The First Mutation badge is a separate trophy from First Legendary, which is why a mutated Common can be worth holding while that badge is still missing. On higher ranks, a mutated Legendary is a coin spike, and a mutated Mythical or Secret is screenshot-before-selling inventory. Gameplay footage illustrates the modifier at work: a squid that got mutated mid-session sold for 4.6 million during a boosted run. The mutation list and acquisition methods are separate topics from this ladder.

First-catch badges and milestone stats

The first-catch badges map onto the rarity list one for one — First Legendary, First Mythical, First Secret, plus First Mutation — and they are rarity badges, not catch-count trophies. Catch-count badges (50 / 250 / 1,000 / 10K / 50K / 100K / 250K / 500K) do not care which rank fills the counter, so the mid-game plan is to keep the first of each headline rank and the first mutation for badges, and sell everything else as fuel.

What to do with a catch at each tier

Tips

Common

Sell; hold only if a mutation you still need is sitting on it.

Legendary

The first one is a badge. After that, sell the extras to fund Strength instead of freezing a full inventory because they look important.

Mythical

Keep the first for First Mythical. After the badge it is a high sell — slow down during busy multi-fish hauls and read the labels so Auto Sell or a sloppy dump does not mix it into a pile of Commons.

Secret

A session event — pause Auto Sell when the silhouette or label looks wrong in a good way and confirm the rank before the inventory clears.

Any tier

Never assume Auto Sell knows your badge goals — turn it off for first-catch and mutation hunts, back on for volume grinding.

How rarity affects sell value

The game does not publish an official per-tier price table, so value comparisons stay relative: Commons are the baseline economy; Legendary sell better than Commons, appear more often than Mythical or Secret, and fund the next Strength buys; a Mythical without a mutation is still a high sell; Secret and mutated headline catches are the spike inventory. The loop that ties value to rarity is that new waters hold rarer fish, and rarer fish sell for the coins that buy even more Strength.

Gameplay footage observed during an admin-boosted session shows the spread in practice: an 11k Legendary fish, and at the top of the run a blacktip shark at 9 million and an orca at 6 million identified as Secret catches. Those are illustrative magnitudes under luck boosts and event conditions — not fixed prices.

Rarity scales with distance, not luck

Close water is common water; far water is where Legendary, Mythical, Secret, and mutated fish live. Rarity scales with distance and location rather than with luck purchases, and the game's own description ties progression to reaching new waters with rarer fish. Strength, a coin upgrade, is what moves that gate: you will not reliably farm Secret fish by standing in the starter ring and buying a luck pass. Luck passes (Lucky, Super Lucky, Ultra Lucky — in that order of spend if you are buying luck at all) only help in water your Strength already reaches. Distance first, luck second.

In-water labels: footage vs. the published ladder

Gameplay footage shows more label words in the water than the published ladder enumerates. Keep the two straight:

Mistakes to avoid

Problem: Reading 'uncommon', 'rare', or 'epic' in-water labels as official rarity tiers
Fix: Those words appear during line steering and catches in gameplay footage, but the published ladder does not enumerate them — it folds everything below Legendary into Common. Treat them as footage observations, not ladder ranks, until the game itself lists them.

Problem: Assigning a fish species to a tier from a video sighting
Fix: Early footage names blue tang, carp, and seahorse while the player steers toward 'rares' instead of 'uncommons'; later footage shows starfish, clownfish ('Nemo'), puffer fish, squid, manta ray, tiger shark, great white shark, blacktip shark, orca, barracuda, and swordfish under 'legendary', 'epic', 'mythical', and 'secret' labels. Species-to-tier assignments are not published, so keep the fish names as footage sightings and use the in-water labels only as session cues.
