Steal A Fish is a base-building tycoon and PvP robbery game on Roblox created by the group MY FISH FRIEND. Players collect fish that swim down a central river conveyor, bring them to a private riverside house to generate passive income, and defend their collection against rival players who can infiltrate bases and steal fish.
Progress in the game relies on upgrading your income per second, defending your property with force fields and defensive tools, and completing structured rebirths to unlock base expansions, speed upgrades, and higher-tier weapons.
Basic Controls and Base Navigation
Navigating the map and managing your base uses standard Roblox controls alongside dedicated interface buttons.
- W, A, S, D: Move your character.
- Spacebar: Jump.
- E: Interact with river fish to buy them, or interact with rival fish to steal.
- Number keys 1–0: Equip unlocked weapons and slap tools.
- Left Mouse Button: Use equipped tool or weapon.
The on-screen interface provides three essential management buttons:
- House: Instantly teleports your character directly in front of your base entrance.
- Rebirth: Opens the progression menu displaying active cash and specific fish requirements for your next rebirth rank.
- Index: Displays your fish collection log across all 13 rarities, tracking which regular and event creatures you have owned.
Inside your base, fish occupy designated display pads. Each creature generates cash automatically every second, which accumulates on green claim buttons on the floor. Stepping over these buttons claims your earnings.
River Spawns, Conveyor Mechanics, and Mutations
All standard fish emerge from a tunnel and swim down the river toward an exit boat at the opposite end of the map. If a fish reaches the boat before a player purchases it, the creature despawns.
Whenever you purchase a fish with in-game cash or Robux, it begins walking toward your house to fill an empty display slot. Players can purchase server-wide boosts directly at the riverbank:
- 2x Fish Speed: Costs $100,000 in-game cash to accelerate how fast fish travel down the river.
- 2x Fish Spawn: Costs $500,000 in-game cash (or 49 Robux) to halve the spawn interval between fish.
Guaranteed spawn timers appear in the interface to announce rare arrivals, including countdowns for guaranteed Mythic, Cosmic, and Deep rarity spawns.
Fish Mutation Rates
Fish spawning from the tunnel have a chance to roll special mutations. These visual variants adjust value and theft properties:
| Mutation | Spawn Chance | Special Effect / Property |
|---|---|---|
| Unstealable | 7.5% | Prevents rival players from picking up or stealing the fish from your base |
| Gold | 5.0% | Multiplies the fish's income rate while retaining standard purchase costs |
| Void | 2.5% | Provides a dark aura aesthetic and elevated tier value |
| Magma | 0.5% | Red-hot visual mutation with increased payout |
| Dead | 0.2% | The rarest river mutation, giving the fish a skeletal aesthetic and boosted earnings |
Base Defense and PvP Stealing Mechanics
Every player's base starts with an open gateway vulnerable to raids. At the back of the house sits a force field button. Pressing this button deploys a blue shield that completely blocks rival players from entering your base.
By default, the free force field lasts 60 seconds before dropping, requiring manual reactivation once the cooldown resets. Players can also purchase an extended 24-hour force field for Robux to protect their collection during prolonged sessions.
How Stealing Works
- Infiltrate an Unprotected Base: When another player's force field expires or drops, you can walk inside and press E on any fish that does not possess the Unstealable mutation.
- Carry Weight Slowdown: Picking up a stolen fish significantly reduces your movement speed, making you easy to catch if the owner pursues you.
- Delivery: You must manually carry the fish back into your own base. Once it reaches your display floor, the fish transfers ownership and generates income for you.
- Base Interception: Owners can slap or shoot thieves to knock them back, forcing them to drop the stolen fish before they escape.
Defensive Tools and Weapon Shop
The tool shop on the map sells slap gloves and ranged weapons to repel invaders. Higher-tier weapons unlock as you reach specific rebirth tiers:
- Silver Slap: Costs $500. Increases knockback distance compared to the basic slap.
- Golden Slap: Unlocked through early rebirths; inflicts a heavier knockback hit.
- Diamond Slap: Costs $100,000,000. Launches opponents backward across large distances.
- Flintlock: Basic projectile firearm that shoots and pushes back incoming raiders.
- Blunderbuss: Heavy-hitting ranged firearm with high knockback, balanced by a long reload time.
- Freeze Gun: Costs $1,000,000,000 (unlocked around Rebirth 5); temporarily freezes targets in place.
- Ice / Freeze Slap: Freezes players on contact to shut down escaping thieves instantly.
- RPG: Explosive weapon purchasable in the shop that sends targets flying with area-of-effect blasts.
- Taser: Costs $500,000,000,000; incapacitates and shocks approaching targets.
Rebirth Requirements and Progression
Rebirthing is the primary method for scaling your base income, unlocking additional floors, expanding fish capacity, and speeding up your character. When you perform a rebirth, the game consumes only the specific fish requested and the designated cash fee; all other fish in your base remain in your possession.
| Rebirth Tier | Cash Required | Fish Sacrificed | Key Unlocks and Stat Bonuses |
|---|---|---|---|
| Rebirth 1 | $500 | 1 Turtle | +Money multiplier, +10s Force Field duration, higher offline income rate, Pistol/Flintlock access |
| Rebirth 2 | ~$1,200–$2,000 | 1 Crab, 1 Tralalero | +Walk speed, +10s Force Field duration, increased offline limit |
| Rebirth 3 | $25,000 | 1 Blobfish, Clownfish | Base Floor 2 unlock, additional fish display slots, +Money multiplier |
| Rebirth 4 | Cash scaling | 1 Nuke Fish, 1 Saw Shark | +1 Fish Slot, +Walk Speed, Diamond Strike / Golden Punch, +10s Force Field |
| Rebirth 5 | $15,000,000 | 2 Whales, 1 Megalodon | Freeze Gun and Ice Slap access, expanded upper-floor slots |
| Rebirth 6+ | $250,000,000+ | Bananini, Goldfish, Kraken, Loch Ness | Advanced tool access (Taser/Cape tiers), multi-million multiplier scaling |
Fish Rarities and Income Scaling
Steal A Fish features 13 distinct rarity tiers: Common, Uncommon, Rare, Epic, Legendary, Mythic, Cosmic, Deep, Abyss, Limited (Robux), Event, Admin, and Secret.
While standard fish pay a fixed dollar amount per second, special Limited, Secret, and select Event units scale dynamically as a percentage of your best-owned fish. When you acquire a new high-earning unit, all percentage-based fish immediately adjust their output to match the new benchmark.
| Fish Name | Rarity Tier | Purchase Price | Base Income per Second |
|---|---|---|---|
| Sea Star | Common | $100 | $5/s |

Endgame Feature: Unlocking the Fish Vault
The Fish Vault is a dedicated storage room located on the top floor of the base. It operates as a secure safety deposit box where rare catches can be stored without risk of theft from other players.
Vault Rules
- No Active Earnings: Fish placed inside the vault do not generate money per second. It is designed to preserve duplicate high-tier units, trade stock, or creatures reserved for upcoming rebirths.
- Friends Allowed Toggle: You can toggle a privacy setting that permits friends on your server to walk in and inspect your vault display.
Unlock and Upgrade Costs
Unlocking the vault requires completing an advanced endgame rebirth with steep resource demands:
- Initial Vault Unlock: Requires 150 Quadrillion cash, 1 Baby Deep Eater, 2 Zholthagru, and 1 Sacabambaspis. Unlocks the room with initial base slots.
- Vault Upgrade (+2 Slots): Requires performing another rebirth tier costing 2.75 Quintillion cash, 3 Star Striders, 1 Aurora Whale, 1 Cthulhu, and 1 Hungry Deer. Players can also purchase a +2 Vault Slots pass for 199 Robux.
Because these creatures have strict spawn windows, players typically target Admin Abuse events—where rapid multi-event rotations dramatically increase high-tier spawn rates—to collect the required event fish.
Frequently Asked Questions
Do you lose all your fish when you rebirth in Steal A Fish?
No. Rebirthing only consumes the specific fish listed as requirements on your Rebirth menu. Any other fish on your base pads remain in your house and continue generating money.
How do you prevent people from stealing your most expensive fish?
Maintain your force field by tapping the button at the back of your base whenever it goes off cooldown, or buy the 24-hour shield. Alternatively, obtain fish with the Unstealable mutation (7.5% spawn rate), which cannot be picked up by invaders even if your gateway is open.
Why do some Secret and Limited fish not show a flat cash per second number?
Creatures like the Demogorgon Worm, Hungry Tung, and Hungry Deer use scaling percentages rather than static values. They calculate their money per second by taking a percentage (such as 120% or 150%) of the highest fixed-income fish currently generating cash in your base.
What should you do if an upper floor collection pad fails to register cash?
If upper floor pads become unresponsive, sell lower-tier clutter taking up base space or step directly across the pad center. If money fails to register completely, rejoin the server; purchased fish remain saved to your profile data.
