Deep Fishing Fish Rarity: First-Catch Milestones

Quick answer

Catch your first Legendary, Mythical or Secret fish to earn its corresponding First Legendary, First Mythical or First Secret badge. Upgrade Strength to throw farther and reach new waters with rarer fish. Keeping a fish is a collection choice; the milestone condition is the first catch.

• Choose Legendary, Mythical or Secret as a first-catch goal.
• In-water labels also include 'uncommon', 'rare' and 'epic'.
• Mutations modify a catch rather than adding a rarity tier. Sale examples below are specific boosted-run values, not fixed prices.

Common: the baseline economy

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 continued fishing. Sell Commons to fund upgrades; keep a wanted variant if you are collecting it. Do not build a museum of Commons while the Strength bar is empty.

Legendary and Mythical

Legendary fish are a mid-game coin engine: they sell better than Commons, show up more often than Mythical or Secret, and fund the next Strength buys.

A Mythical hunt gives you a collection goal while you 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. Both Legendary and Mythical labels appear on catches.

Keeping a Secret catch

If you want to keep a Secret, pause Auto Sell and check the catch's label before selling it.

Mutations are a modifier, not a rarity tier

Mutations modify a catch that was already made; they do not replace its rarity. A mutated Common is still not a Secret. First Mutation is a separate trophy. Holding a mutated Common is a collection choice, not a badge prerequisite. For sale value, a mutated Legendary is a coin spike, and a mutated Mythical or Secret is screenshot-before-selling inventory. For example, a squid mutated during a boosted run sold for 4.6 million. The mutation list and acquisition methods are separate topics from these first-catch goals.

First-catch badges and milestone stats

Choose a milestone below and catch the corresponding fish. These milestones depend on catching the fish, not retaining it. Catch-count badges (50 / 250 / 1,000 / 10K / 50K / 100K / 250K / 500K) count catches regardless of rank, so sell unwanted catches to fund upgrades and keep the variants you want to collect.

Choosing what to sell or keep

Tips

Common

Sell for upgrade funds, or keep a wanted variant for your collection.

Legendary

Sell unwanted extras to fund Strength instead of freezing a full inventory because they look important.

Mythical

Read labels during multi-fish hauls so you can choose which valuable catches to sell or keep.

Secret

Choose whether to keep it for your collection.

Any tier

Use Auto Sell for volume grinding, or turn it off when you want to inspect and keep particular catches.

How rarity affects sell value

Sell unwanted catches to fund upgrades. The examples below illustrate individual catches rather than a fixed per-tier price table.

An admin-boosted run included an 11k Legendary fish, a blacktip shark at 9 million and an orca at 6 million, with the shark and orca labeled Secret. Those are illustrative magnitudes under luck boosts and event conditions — not fixed prices.

Reach new waters with Strength

Spend coins on Strength to throw farther, then cast into the newly reachable waters containing rarer fish. Sell unwanted catches to fund the next upgrade. This gives you a concrete progression action while pursuing the first-catch milestones.

Reading in-water labels

Use the catch's displayed label when deciding what you have caught:

Mistakes to avoid

Problem

Treating the three first-catch goals as every in-water label

Fix

'Uncommon', 'rare' and 'epic' also appear during line steering and catches. Read the displayed label to identify the catch.

Problem

Using species names alone to identify rarity

Fix

Fish you may encounter include blue tang, carp, seahorse, starfish, clownfish ('Nemo'), puffer fish, squid, manta ray, tiger shark, great white shark, blacktip shark, orca, barracuda and swordfish. Check the individual catch's label; this species list is not a fish-per-tier table.
