The Fish Vault is one of the biggest features added with the Vault Update in Steal a Fish.
It isn’t just a storage room, it’s a whole new system that changes how you manage your rarest catches.
But unlocking it isn’t as simple as clicking a button. You’ll need money, rare fish, and some serious grinding.
Here’s everything you need to know about unlocking, upgrading, and using the Fish Vault effectively.
What is the Fish Vault in Steal a Fish?
The Fish Vault is a secure storage room that sits on the top floor of your base. Think of it like a safe deposit box for your most valuable catches.
Once unlocked, you can place rare or event-exclusive fish inside, keeping them safe for:
-
Future rebirths (so you don’t accidentally lose key fish)
-
Trading (keep high-value fish ready for deals)
-
Flexing (friends can visit your vault if you enable the “friends allowed” feature)
Important: Fish stored in the vault do not generate money. They’re locked away until you take them out, so you’ll need to decide carefully which ones go inside.
How to Unlock the Fish Vault
Unlocking the Vault requires completing a specific rebirth level, and the requirements are steep.
Here’s the full checklist:
- 150Qa (150 Quadrillion) Money
- 1x Baby Deep Eater
- 2x Zholthagru
- 1x Sacabambaspis
Pro Tip: Start collecting these fish early, even before you have the money saved. Rare fish like Zholthagru and Sacabambaspis can take hours to spawn, so having them ready prevents delays when you finally hit 150Qa.
Best chances to catch them? Admin Abuse events. These events massively increase rare fish spawns, so don’t miss them.
Once you complete the rebirth with the above requirements, the Vault unlocks and becomes accessible inside your base.

How to Upgrade Fish Vault Slots
The Vault doesn’t give you unlimited storage at first. You’ll quickly notice how few slots you get, especially if you’re hoarding rare event fish. Luckily, upgrades exist, but they’re even tougher to unlock.
Vault Upgrade Requirements:
- 2.75Qi (2.75 Quintillion) Money
- 3x Star Striders
- 1x Aurorawhale
- 1x Cthulhu
- 1x Hungry Deer
The money jump alone is massive, and the fish list is no joke. Star Striders are rare, while Aurorawhale and Cthulhu are among the toughest to find. Plan ahead and grind during boosted spawn events.
Each upgrade gives you +2 extra vault slots, letting you store more rare catches safely.
Best Ways to Use the Fish Vault
Since fish in the Vault stop generating money, you’ll want to be strategic:
-
Keep money-makers outside. Don’t store your highest-income fish if you’re still grinding cash.
-
Store duplicates of rare fish. If you have multiple Zholthagru or Cthulhu, the Vault is perfect for keeping spares.
-
Save rebirth requirements. Place fish you’ll need later so you don’t accidentally sell or sacrifice them.
-
Flex your collection. Enable the “friends allowed” option and let your buddies check out your rarest catches.
Tips to Unlock Faster
-
Grind early: Start saving money and collecting rare fish long before you hit 150Qa.
-
Use Admin Abuse wisely: These events make farming rare fish significantly easier.
-
Balance progress: Don’t lock away too many high-value earners. You’ll still need income for the next rebirth.
-
Upgrade smartly: Only go for upgrades when your economy is stable, don’t cripple your progress by rushing.
Final Thoughts
The Fish Vault is more than just storage, it’s a long-term strategy tool in Steal a Fish. Unlocking it takes a grind of 150Qa and rare fish farming, but once you have it, you’ll finally have a safe place to stash event-exclusive catches and prep for future rebirths.
The key is planning ahead: collect the required fish early, use Admin Abuse events, and don’t sacrifice your income flow just to fill the Vault. With smart management, the Fish Vault will become one of the most powerful tools in your journey to becoming the ultimate fish hoarder.
