My Fishing Brainrots Complete Guide (2026)
How My Fishing Brainrots Works
The gameplay loop is dead simple:
- Buy eggs from the conveyor
- Hatch brainrot pets
- Brainrots fish automatically in the pond
- Fish go into boxes
- Sell boxes for cash
- Buy better eggs
- Upgrade your brainrots
- Rebirth for permanent bonuses
- Repeat forever
Your First 30 Minutes
When you spawn, you get some starting cash. Here's exactly what to do:
- Walk to the egg conveyor (big machine in the center)
- Buy the cheapest egg available
- Place it on your plot
- Wait for it to hatch
- Watch your first brainrot start fishing
Your starter brainrot is probably Common rarity. It fishes slow. That's fine. You need cash flow before you can be picky. Once you have one brainrot working, buy another egg. Fill your available slots. More brainrots = more fish = more money.
The Egg System
Eggs are everything in this game. Better eggs mean better brainrots.
Egg Rarities
| Rarity | Brainrot Quality | Spawn Timer |
|---|---|---|
| Common | Worst | Always available |
| Uncommon | Below average | Short wait |
| Rare | Decent | Medium wait |
| Epic | Good | Longer wait |
| Legendary | Excellent | Long wait |
| Mythic | Best | Very long wait |
Egg Buying Strategy
Don't spam Common eggs after the first hour. One Legendary brainrot outfishes like 8 Commons. The math isn't even close.
- First hour: Buy Commons to fill all slots
- Hours 2-5: Save for Rare/Epic eggs only
- After first rebirth: Legendary and Mythic only
Brainrot Rarities Explained
Your brainrots determine everything. Higher rarity = faster fishing = better fish = more money.
| Rarity | Fishing Speed | Fish Quality | Worth Keeping? |
|---|---|---|---|
| Common | Very slow | Basic fish | Early game only |
| Uncommon | Slow | Basic fish | Replace ASAP |
| Rare | Decent | Better fish | Mid-game staple |
| Epic | Fast | Good fish | Keep these |
| Legendary | Very fast | Great fish | Definitely keep |
| Mythic | Insane | Best fish | Never delete |
Special Brainrots
- Rainbow variants have boosted stats
- Golden variants earn bonus cash
- Event brainrots (like The Grinch) have unique abilities
Upgrading Your Brainrots
Don't just hatch and forget. Upgrading is how you actually progress.
How to Upgrade
- Walk up to a brainrot
- Click the green arrow below its name
- Spend cash to level it up
Each level increases fishing speed, fish quality caught, and cash per fish.
Upgrade Priority
- Your highest rarity brainrot first
- Then work down the list
- Don't waste cash upgrading Commons
One maxed Legendary beats five half-upgraded Rares. Focus fire on your best brainrots.
The Fish Index
This is the secret progression system most players miss. Every fish your brainrots catch gets logged in the Fish Index. When you complete entries, you unlock permanent cash multipliers.
Fish Index Rewards
| Index Milestone | Reward |
|---|---|
| 10 fish types | +10% cash |
| 25 fish types | +25% cash |
| 50 fish types | +50% cash |
| 100 fish types | +100% cash |
These bonuses are PERMANENT. They survive rebirth. This is why you want diverse brainrots catching different fish types, not just raw income.
Fish Index Tips
- Higher rarity brainrots catch rarer fish
- Different brainrots catch different fish types
- Check your index regularly to see what you're missing
- Some fish only appear at certain times or conditions
The Rebirth System
Rebirth is how you break through plateaus. It wipes your progress but gives permanent bonuses.
What You Lose
- All your cash
- All your brainrots
- Your current upgrades
What You Keep
- Fish Index progress
- Permanent multipliers
- Rebirth bonuses
When to Rebirth
Rebirth when progress feels painfully slow. 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.
Strategy: Max out your current brainrots first, complete as much Fish Index as possible, then rebirth. Each rebirth cycle should take you further than the last.
Offline Earnings
The best part of this game. Your brainrots keep fishing when you're not playing. But there's a cap - you can only accumulate so much offline before it stops counting. Capped after about 4 hours.
Maximizing Offline Gains
- Fill all brainrot slots before logging off
- Prioritize high-rarity brainrots (they earn more per hour)
- Check back every 3-4 hours if possible
- Upgrade your offline cap when available
Upgrades Menu
Beyond individual brainrot upgrades, there's a global upgrades menu. These affect everything:
| Upgrade | Effect |
|---|---|
| Better Fishing Luck | Higher chance of rare fish |
| Faster Conveyor | Reduces egg spawn timers |
| More Slots | Additional brainrot capacity |
| Offline Boost | Increases offline earnings cap |
Priority Order
- More Slots (more brainrots = more income)
- Offline Boost (passive gains are huge)
- Faster Conveyor (better eggs faster)
- Better Fishing Luck (nice but not essential)
Common Mistakes to Avoid
- Spamming Common eggs - Stop after the first hour
- Spreading upgrades evenly - Focus on your best brainrots
- Ignoring the Fish Index - Those permanent multipliers matter
- Rebirthing too early - Build up first
- Forgetting offline caps - Check back every few hours
- Deleting Mythics for space - Never. Ever.
