Fish It Forgotten Fish: Astrelle Secret & Drop Rates

The Fish It forgotten fish category is the single most confusing tier in the entire game, because every creature sitting in this band carries a "Secret" or "Forgotten" rarity label that confuses new players about whether they can actually be caught or whether the entries are just flavor text. Recent updates added the Forgotten Hydras, a highest-rarity entry, plus six new pets hatched from the latest Pet Egg, which expanded the hidden-fish pool considerably. Understanding which forgotten fish you can realistically target — and which ones are locked behind the Astrelle secret — is the difference between farming coins efficiently and burning hours at a pond for nothing. This guide breaks down every entry in the band, the islands where they appear, and the sell values you can expect once you finally land one.

The Forgotten Rarity Band, Decoded

The "Forgotten" label in Fish It is not a single rarity — it is a collection of off-meta, lore-flavored entries that the developer added across the Arcadia, Withering Core, and 8-Bit updates. Some sit at the top of the standard rarity ladder, while others are classified as Secret because their spawn conditions are deliberately obscured. Players hunting these fish need to think in terms of three buckets: reachable Forgotten, gated Forgotten, and Astrelle-exclusive Forgotten.

The reason this distinction matters is that fishing time is the most limited resource in the game. If you spend three hours grinding the starter pond chasing an entry that only spawns on the Withering Core island, you will never see it. The official Fish Atelier group on Roblox is the best place to confirm whether a forgotten entry is still active or has been vaulted, because the developer announces vaulted entries in the group feed before pulling them from the rotation.

What "Secret" Really Means in Fish It

The term Secret is reserved for fish that do not show up in your index until you catch them at least once. They are not visible in the bestiary, you cannot preview their silhouette, and the sell value is hidden until first capture. The Astrelle sigil sits in this category, alongside other well-known Secret entries such as the Megalodon and the Thunderzilla. A full fish spawn rate breakdown covers which Secret entries are still active and which have been retired from rotation, but for the forgotten band specifically, the Astrelle-related entries are the only ones that remain permanently gated behind a hidden unlock.

Why the Band Is Worth Farming

Forgotten fish carry sell values that are roughly 4x to 12x a comparable Common catch from the same island, which makes them the most profitable short-term farming target for mid-game players. If you are running a Trident rod with a luck build, you can expect to land one Forgotten entry roughly every 45 to 90 minutes of focused fishing on the right island. Compare that to farming Common fish for coins, where you would need to catch 30 to 50 fish to match the same payout, and the math quickly favors chasing the rare entries. Rod stats and luck scaling matter heavily here, so reviewing your rod tier and luck numbers before committing to a Forgotten grind is worth the time.

Fish It Forgotten Fish by Island

Spawn locations in Fish It are locked to specific islands, and the Forgotten band respects that rule strictly. The Forgotten Eel is a Coral Reef exclusive, the Forgotten Angler only appears at Snowcap Peak, and the new Forgotten Hydras added in the most recent patch are tied to the Withering Core expansion. If you are hunting a specific entry, you must travel to its island — there is no cross-island spawn sharing for this tier.

Weather triggers are a big deal in this band. The Forgotten Angler will not spawn during a sunny block on Snowcap Peak, which means checking the island's live weather before teleporting in saves a wasted trip. The Withering Core entry is the only Forgotten fish without a weather gate, which is part of why it became the most-hunted new addition in the patch. Players building a rotation around the world map and island layout tend to chain Snowcap Peak → Withering Core → Ember Isles because all three Forgotten entries are reachable inside a single play session.

The Withering Core Entry

The Forgotten Hydra is the highest-rarity Forgotten fish added so far, and the only one that sits in the Mythic band rather than Legendary. Reported drop rates from community testing put the spawn at roughly 1 in 4,500 to 1 in 6,000 casts with a max-luck Trident, which is harsh but achievable. The entry does not require a special unlock, so any player with the Withering Core expansion unlocked can target it. The sell value alone is one of the strongest in the entire game, and landing two or three in a farming session can cover a mid-tier rod upgrade without any other income.

Snowcap Peak and the Forgotten Angler

The Forgotten Angler is the gateway Forgotten entry because Snowcap Peak is reachable from a relatively early player level, and the rod requirement is forgiving. A Reinforced Rod with a modest luck build can pull one in roughly two to three hours of focused play, which is dramatically better odds than the Hydra. Community data suggests Snowcap Peak sees a 3x spawn boost during snow weather, so waiting for a snow forecast is the most efficient way to approach this entry.

Astrelle Secret and How It Affects Forgotten Fish

The Astrelle secret is a hidden chain of in-game events that unlocks a small cluster of exclusive entries, including at least one Forgotten fish that only appears after the secret is fully completed. The chain involves collecting a fragment from each of the four elemental islands, fishing a specific bobber pattern in the Astrelle Hollow at midnight server time, and then catching a unique "key" fish that triggers the unlock animation. Until that animation fires, the Astrelle Hollow island is empty — there is no preview, no NPC, and no obvious hint that the area is interactive.

The chain is intentionally punishing, and failing step 5 means losing the fragment progress for that server day. Players who attempt the secret without the right bobber will catch Common-tier junk fish and waste the midnight window. The reward is the Astrelle Sigil Fish, which sits in the Secret band and is currently the only Forgotten-tier entry that is permanently locked behind the Astrelle chain. If you want to clear every Forgotten entry in your index, this is the one you cannot shortcut.

Why the Secret Exists

According to community reports, the Astrelle chain was added to give veteran players a long-term chase that does not depend on raw luck. Most Forgotten fish are pure RNG, which means players who happen to have a max-luck rod can farm them in a few hours. The Astrelle secret cannot be cheesed with luck — it requires correct sequencing and server-time awareness, which makes the Astrelle Sigil Fish a true status symbol. A small number of players have completed the chain since launch, and the entry remains rare enough that its sell value has not dropped even after the most recent patches.

Forgotten Fish Mistakes When Attempting the Secret

The single most common mistake is casting with a regular bobber instead of the Astrelle Bobber, which is a craftable consumable that must be in your inventory before you start step 5. Another common error is attempting step 5 on the wrong server day — the chain is gated to a specific calendar window that resets weekly. Players who finish steps 1-4 should note the exact date and only attempt the midnight cast on the day the chain unlocks, otherwise they will burn the bobber for nothing.

Drop Rates and Spawn Chances

The Fish It forgotten fish drop rates are not officially published, but community testing across thousands of casts gives a reliable picture. The key variables are rod luck, active weather, time of day, and whether you are using a luck potion from a code. The table below shows the realistic spawn ranges reported by players running optimized setups, with separate columns for a mid-game rod versus a max-luck endgame rod.

These numbers are based on community testing as of the 2026-09-20 patch and may shift if the developer rebalances the rotation. Players running mutation builds should also note that some mutation events and potions can stack with luck potions, but they do not directly increase Forgotten spawn chances — they modify the value of the catch once it is already in your inventory.

Reading the Numbers Correctly

A "1 in 280" drop rate does not mean you will see one every 280 casts exactly. What it means is that over a large sample size, the average converges on 280 casts per Forgotten Eel. In practice, you might go 500 casts without one and then pull two in 50 casts, because the spawn rolls independently each cast. The way to use the table is to estimate your expected session yield, not to predict a specific cast. If you have two hours to play, and a max-luck rod, and you are fishing the right island with the right weather, plan for one or two Forgotten catches per session.

How Luck Potions Stack

A standard Luck Potion from the active code pool multiplies your effective luck by roughly 1.6x for 30 minutes. If you stack it on top of a max-luck rod that already has a 4.2x modifier, your effective luck for those 30 minutes is around 6.7x, which is why the right column of the table shows nearly half the drop-rate denominator. The most efficient way to use potions is to save them for the right island and weather, then burn them in a focused 30-minute window. Wasting a potion on a Common-tier fishing session is one of the most common coin-farming mistakes reported in the community.

Sell Values and Farming Strategy

Sell values for the Forgotten band are stable because the entries are capped in supply and the developer has not nerfed them in recent patches. The Forgotten Hydra is the highest-value entry, followed by the Astrelle Sigil Fish for players who have completed the chain. The table below shows the Fish It fish selling prices for each entry, plus a "coins per hour" estimate for a max-luck grind.

The Hydra is the clear top earner per hour, but the Clockfish during the 8-Bit event and the Bonefin during fog are the best mid-tier targets because their spawn rates are friendlier. A balanced rotation that chains Snowcap Peak → Withering Core → Shipwreck Cove across one play session can realistically clear 1.2 to 1.5 million coins in two to three hours, which is enough to fund the next major rod upgrade or pet hatch.

Sell Now or Wait for a Multiplier

Most Forgotten entries should be sold immediately, because the sell value is the same whether you bank them in a storage tank or turn them in at the merchant. The exception is the Astrelle Sigil Fish, which some collectors hold because the developer has hinted at a future crafting recipe that may consume the entry. There is no confirmed use for the Hydra beyond selling, so banking it is purely cosmetic. The general rule is: if you are not actively trying to complete a collection achievement, sell on the same day you catch it.

Long-Term Farming Plan

For players who want to commit to a long-term Forgotten grind, the most efficient play is to unlock Withering Core as your first priority, because the Hydra is the highest-yield entry and the only one that can sustain a full-time farming session. After that, chain Snowcap Peak and Ember Isles for the mid-tier entries, then complete the Astrelle chain when you have the time to commit to a full week of prep. The setup cost is a max-luck rod, a small stockpile of Luck Potions, and enough patience to weather the dry streaks. Once the rotation is running, the coin income is more consistent than any other farming method in the game.

Frequently Asked Questions

What is the Fish It forgotten fish tier exactly?

The Fish It forgotten fish band is a collection of high-rarity entries added across the Arcadia, Withering Core, and 8-Bit updates that share a "Forgotten" or "Secret" rarity label. They are not a single uniform tier — some sit at Legendary, some at Mythic, and the Astrelle Sigil Fish is gated behind a hidden quest chain. Sell values range from roughly 380,000 to 1,250,000 coins per catch, which makes them the most profitable short-term farming targets in the game.

How do you unlock the Astrelle secret in Fish It?

The Astrelle secret requires catching four elemental fragment fish on Ember Isles, Crystal Depths, Snowcap Peak, and Coral Reef, then casting with the Astrelle Bobber at the Astrelle Hollow island at exactly midnight server time. The chain unlocks a key fish that, once caught, reveals the Astrelle Sigil Fish as a permanent spawn. Failing any step resets that day's progress, so timing and bobber preparation are critical.

Which island has the best Forgotten fish drop rates?

Withering Core has the highest single-entry value with the Forgotten Hydra, but Snowcap Peak and Ember Isles offer the best drop rate per cast because their entries sit in a friendlier spawn bracket. For pure coins-per-hour, the best rotation chains Snowcap Peak during snow, Ember Isles during the day, and Withering Core at night, which covers three Forgotten entries in a single focused session.

Are Forgotten fish affected by luck potions?

Yes, standard Luck Potions stack with your rod's base luck modifier and roughly multiply your effective luck by 1.6x for 30 minutes. A max-luck rod with an active potion hits roughly 6.7x effective luck, which can cut drop-rate denominators by half. Save potions for the right island and weather, because burning one on a Common-tier session is wasted coin value.

Should I sell Forgotten fish or save them for crafting?

Sell them on the same day you catch them in most cases, because the merchant payout is the same whether you bank the entry or cash it in. The only exception is the Astrelle Sigil Fish, which some collectors hold because the developer has hinted at a future crafting recipe that may consume the entry. Other Forgotten entries have no confirmed secondary use beyond selling, so holding them is purely cosmetic.
