My Fishing Brainrots Rebirth Guide (2026)
What is Rebirth?
Rebirth is how you break through plateaus in My Fishing Brainrots. It wipes your current progress but gives permanent bonuses that make future progression faster. It's the primary way to unlock upper floors for your base and increase your overall income potential.
Key Concept: Rebirth resets your cash and brainrots, but the permanent multipliers you gain make each new run faster than the last. Each rebirth cycle should take you further than the previous one.
What You Lose on Rebirth
- All your cash - Everything resets to zero
- All your brainrots - Your entire collection is wiped
- Your current upgrades - All level progress is lost
- Current floor progress - You start fresh on a new floor
What You Keep
- Fish Index progress - All fish you've collected remain logged
- Permanent multipliers - Fish Index bonuses stay active
- Rebirth bonuses - All previous rebirth multipliers stack
- Unlocked floors - New floors remain accessible
- Equipment upgrades - Global upgrades like Fishing Luck persist
Rebirth Requirements
Each rebirth needs specific requirements. Check the Rebirth button in-game to see exact requirements. Don't rebirth the moment you can - build up first.
Rebirth 1
Requirements: $100,000 cash and a specific Rare Pet
Rewards: Unlocks second floor, +10% money multiplier, extra fishing spots
Rebirth 2
Requirements: $1 Million and a higher-tier brainrot
Rewards: More fishing spots, additional 10% multiplier (total +20%)
Rebirth 3
Requirements: Higher cash and specific units
Rewards: +30% total multiplier, additional floor space, third floor
Rebirth 4+
Requirements: Increasing cash amounts (millions to trillions/quadrillions)
Rewards: Access to Mythic units, higher multipliers, more floors (up to 4th floor and beyond)
When to Rebirth
The golden rule: Rebirth when progress feels painfully slow.
Example: If you're earning 10k/minute and the next egg costs 500k, that's 50 minutes of waiting. After rebirth, your multipliers might cut that to 20 minutes. Worth it.
If you're stuck waiting hours for the next meaningful upgrade, it's time to rebirth.
Signs It's Time to Rebirth
- You've hit the rebirth requirements
- Progress has slowed to a crawl
- You've maxed out your current brainrots
- You've completed as much Fish Index as possible
- The next meaningful upgrade is hours away
Rebirth Strategy
Before Rebirthing
- Max out your current brainrots - Get as much value as possible before reset
- Complete Fish Index milestones - These permanent bonuses survive rebirth
- Upgrade your Barbecue Grill - The passive income helps you rebuild fast
- Fill all slots - Maximize your current income before reset
- Save up resources - Have a plan for quick recovery
After Rebirthing
- Use Barbecue Grill income - The passive income helps you buy back high-tier eggs almost instantly
- Fill new floor space - Take advantage of additional slots
- Rush back to where you were - With multipliers, you'll get there faster
- Push further - The permanent bonuses let you progress beyond your previous limits
- Repeat the cycle - Each rebirth should take you further
Rebirth Multiplier Stacking
Rebirth multipliers stack additively. Here's how they accumulate:
| Rebirth | Multiplier Added | Total Multiplier |
|---|---|---|
| Rebirth 1 | +10% | 1.10x |
| Rebirth 2 | +10% | 1.20x |
| Rebirth 3 | +10% | 1.30x |
| Rebirth 4+ | +10% each | 1.40x, 1.50x, etc. |
Note: These multipliers stack with Fish Index bonuses. With Rebirth 3 (+30%) and 50 fish types (+50%), you're earning 1.95x base income. The compounding effect is massive.
Common Rebirth Mistakes
- Rebirthing too early - Don't rebirth the moment you can. Build up first, complete Fish Index milestones, max out brainrots
- Not upgrading the Grill - The Barbecue Grill is your lifeline post-rebirth. Upgrade it before rebirthing
- Ignoring Fish Index - Complete as much as possible before rebirth. Those permanent bonuses are huge
- Rebirthing with empty slots - Fill all slots and maximize income before reset
- Not planning recovery - Have a strategy for quickly rebuilding after rebirth
Optimal Rebirth Timing
Early Game (Rebirth 1-2)
Rebirth as soon as you meet requirements and have completed some Fish Index progress. The early multipliers are crucial for breaking through the initial grind.
Mid Game (Rebirth 3-5)
Take your time. Max out brainrots, complete Fish Index milestones (aim for 25-50 fish types), and ensure your Grill is upgraded. The multipliers are still valuable but recovery takes longer.
Late Game (Rebirth 6+)
Rebirth when you've hit a hard wall. With high multipliers and Fish Index bonuses, you'll recover quickly. Focus on completing Fish Index to 100 types for the permanent 2x multiplier.
Pro Tips
- Each rebirth adds more fish spots and increases your money multiplier - The benefits compound
- Rebirthing is essential for unlocking access to higher-tier units - Mythics and Divines require higher rebirth levels
- Plan your rebirths around major game updates - New content often requires higher rebirth levels
- Fish Index progress survives rebirth - Complete as much as possible before each rebirth
- The Barbecue Grill is your best friend - Its passive income makes post-rebirth recovery trivial
- Don't rush - Each rebirth cycle should take you further. If you're not progressing faster, you're rebirthing too early
