Fish an Anime RNG Best Gem Upgrades: What to Buy and When

Quick answer

Spend Gems on extra platforms, additional research slots, and food improvements first; pick up Triple Hook and Auto Sell in the mid-to-late game, and leave Infinite Backpack for last because of its high price. All of these are permanent purchases from the Gem Store.

• Early: extra platforms, additional research slots, food improvements
• Mid to late: Triple Hook, Auto Sell
• Late: Infinite Backpack

Gem Store items and what they permanently do

The Gem Store is the gem-funded side of the shop: it holds permanent upgrades and game passes bought with Gems, rather than the cash used by the regular Upgrades shop. Several items also carry a Robux price as an alternative if you prefer to save Gems, and store footage shows players buying game passes directly with Gems.

Comparison

Comparison

Gem Store Item	What You Get
Auto Cash Collect	Collects plot income without manual pickups
Triple Hook	Multiple catches per cast
+1 Equip Characters	An extra plot slot for a placed character
Auto Sell	Clears junk catches automatically
Infinite Backpack	Removes the catch storage cap
VIP	Bundled account perks

Auto Cash Collect and Triple Hook stand out from this list: they remove the two most repetitive inputs in the loop, and Auto Cash Collect is the single purchase that turns a session of clicking into a base that runs itself.

Gem Store prices: Gems vs Robux

Prices below were reported on August 26, 2026 — recheck the store after every update. The same report's headline advice: prioritize the automation and platform upgrades first, since they compound your income over time.

Data table

Data table

Upgrade	Gem Cost	Robux Cost
Auto Sell	120K	240
Triple Hook	40K	1,000
Infinite Backpack	1,750K	—
Platform 1	1,000	—
Platform 2	32,000	—
Second Researcher	240	—
Third Researcher	640	—
2x Food	640	—
4x Luck	—	1,400
2x Luck	—	280
2x Potion Time	—	40
VIP	—	120
Auto Collect	—	40

Rows with a dash under Gem cost were listed as Robux-only, so treat their purchase currency as unconfirmed until you check in game. Two mismatches matter when planning: VIP is listed at 120 Robux with no Gem price, yet store footage shows VIP being bought with Gems; and "Auto Collect" is listed at 40 Robux while Auto Cash Collect is described as a gem-funded purchase. Confirm the item name and currency in your own store before saving Gems for either.

Recommended Gem spending order by stage

Gems are slow to earn, so the order you buy in matters more than which upgrade looks strongest in isolation. Early purchases should widen your income base; later ones should remove the manual work.

• Early: extra platforms, additional research slots, food improvements
• Mid to late: Triple Hook, Auto Sell
• Late: Infinite Backpack

Creator guidance gives the same shape: prioritize permanent upgrades that improve your progression. Triple Hook and Auto Sell become more useful for longer fishing sessions later, while Infinite Backpack is better saved for much later because of its high price.

The reasoning behind each tier: extra platforms come first because every added slot is a permanent increase to total income. Triple Hook multiplies what each cast returns, and Auto Sell removes the constant trips back to storage. Infinite Backpack is last only because it is expensive, not because it is weak — once you own it, storage stops being a constraint entirely.

Storage headroom also gates idle play: upgrade backpack space through rebirths and Gem purchases before you plan a long AFK stint. When storage fills, auto-fishing stops producing and the rest of the session is wasted.

Quick Fish and double offline earnings

Quick Fish is described as an early Gem purchase, and it pairs with Auto Fish to handle the fishing input for you once unlocked.

Offline earnings cap at 50% of active income. You can double them for 20K Gems (or a matching pass), and triple them with Robux when you rejoin — a straightforward Gem sink that raises everything you earn while away.

Gem Store items seen in late-game footage

A late-game playthrough shows Gem Store items beyond the tables above. These come from player footage, so their Gem prices are not confirmed — check the store in game before budgeting for them.

Tips

Second Researcher

Endorsed on the spot as worth buying. It also appears at 240 Gems in the August 26 price report above.

Cheaper level-ups

Level ups are 75% cheaper — the player buys it immediately and calls it that good. No confirmed Gem price.

Longer potion duration

Potions last longer; the player notes being out of Gems right after. No confirmed Gem price.

Faster catch time, extra backpack, one more equip

Faster catch time, another backpack, and one more character equip all appear in the same run. No confirmed Gem prices.

Increased ascended chance

"You can buy all of it with gems," per the footage. It was shown priced at "1.2 mil," but the units are not confirmed — do not budget as if that means 1.2 million Gems.

Luck nodes and potion-time passes: when they fit

In the broader upgrade priority list, Gem-shop luck nodes sit fourth — buy them after you stabilize rebirth loops, behind the base luck upgrades, offline earnings, and the next rod tier. Gem Store luck passes and 2x Potion Time are ranked on the gem shop page. Concentrate rather than spread: spreading Gems across five minor buffs loses to one permanent luck tier every time.

One caveat before you save for them: the price report above lists 2x Luck, 4x Luck, and 2x Potion Time as Robux-only, so confirm the purchase currency in game before setting Gems aside for them.

Every price and effect on this page was reported between late August and early September 2026. Recheck the Gem Store after the next update, and re-order your purchases if prices or mechanics change.
