Best My Fishing Brainrots: Mythic and Rainbow Mythic brainrots sit at S+ tier with insane fishing speed and income. Legendary brainrots are your realistic endgame goal. Delete Commons after hour 1 and never upgrade anything below Epic.
After hatching 300+ eggs, I've got a solid feel for which brainrots actually matter. Rarity matters more than anything else, but there's nuance within each tier that can make or break your progression.
Quick Tier List
| Tier | Brainrots |
|---|---|
| S+ | Mythic brainrots, Rainbow Mythics |
| S | Legendary brainrots, Event exclusives (The Grinch) |
| A | Epic brainrots, Golden variants |
| B | Rare brainrots |
| C | Uncommon brainrots |
| D | Common brainrots |
S+ Tier (Best in Game)
Mythic brainrots are the endgame. If you hatch one, protect it with your life.
| Brainrot Type | Fishing Speed | Fish Quality | Notes |
|---|---|---|---|
| Mythic (any) | Insane | Best fish | Rarest hatch, keep forever |
| Rainbow Mythic | Insane+ | Best fish | Boosted stats, ultra rare |
Why Mythics Dominate
One Mythic brainrot generates more income than your entire starting lineup combined. The fishing speed is ridiculous. They catch fish so fast the boxes fill up before you can sell them.
I got my first Mythic around hour 15. Immediately doubled my income. That's not an exaggeration. The gap between Legendary and Mythic is massive.
Rainbow Variants
Rainbow brainrots have boosted base stats. A Rainbow Mythic is the absolute peak. I've seen exactly one in my entire playtime. The owner's income was triple mine with the same number of brainrots.
If you hatch a Rainbow Mythic, you've won the game.
S Tier (Excellent)
Legendaries are your realistic endgame goal. Mythics are luck-based, but you can reliably farm Legendary eggs.
| Brainrot Type | Fishing Speed | Fish Quality | Notes |
|---|---|---|---|
| Legendary (any) | Fast | Great fish | Target these |
| The Grinch | Fast | Great fish | Christmas event exclusive |
| Golden Legendary | Fast+ | Great fish | Cash bonus on catch |
Legendary Breakdown
Every Legendary brainrot is worth keeping. The specific character doesn't matter as much as the rarity. A Legendary Skibidi catches the same quality fish as a Legendary Bombardiro.
That said, some Legendaries have slightly better base stats. The variance is small enough that you shouldn't stress about it. Any Legendary is a win.
The Grinch (Event Exclusive)
The Christmas 2025 event added The Grinch brainrot. This thing is busted. It has Legendary-tier stats but with a unique passive that increases fish value during certain hours.
If you missed the event, you missed out. The Grinch might return next Christmas, but no guarantees.
Golden Variants
Golden brainrots give bonus cash per fish caught. A Golden Legendary is a Legendary with a permanent cash multiplier. Valuable if you get lucky.
A Tier (Great)
Epic brainrots are your mid-game workhorses. They're common enough to collect multiples but strong enough to carry you through rebirth.
| Brainrot Type | Fishing Speed | Fish Quality | Notes |
|---|---|---|---|
| Epic (any) | Fast | Good fish | Mid-game staple |
| Golden Epic | Fast+ | Good fish | Worth upgrading |
| Rainbow Epic | Fast+ | Good fish | Better than base Epic |
Epic Strategy
Fill your base with Epics before chasing Legendaries. Seriously. Four Epics outperform one Legendary in total income. Quantity matters at this tier.
Once you have 6+ Epics, then start saving for Legendary eggs. The income from your Epic army funds the Legendary hunt.
Upgrade Priority
Max out your Epics before spreading upgrades around. A level 10 Epic beats a level 1 Legendary in raw income. Upgrades matter more than rarity until you hit the level cap.
B Tier (Decent)
Rare brainrots are fine. Not special, but they get the job done early-mid game.
| Brainrot Type | Fishing Speed | Fish Quality | Notes |
|---|---|---|---|
| Rare (any) | Decent | Better fish | Replace when possible |
| Golden Rare | Decent+ | Better fish | Keep longer than base |
| Rainbow Rare | Decent+ | Better fish | Worth upgrading |
When to Replace Rares
Keep Rares until you have enough Epics to replace them. Don't delete a Rare to make room for a Common. That's backwards.
My rule: replace Rares one-for-one with Epics. Never downgrade.
C Tier (Below Average)
Uncommon brainrots exist to fill slots early game. That's it.
| Brainrot Type | Fishing Speed | Fish Quality | Notes |
|---|---|---|---|
| Uncommon (any) | Slow | Basic fish | Replace ASAP |
Uncommon Reality Check
Uncommons are barely better than Commons. The fishing speed increase is noticeable but not game-changing. Replace them the moment you hatch something better.
Don't waste upgrade resources on Uncommons. Ever.
D Tier (Worst)
Common brainrots are your starter pets. They serve one purpose: generating enough cash to buy better eggs.
| Brainrot Type | Fishing Speed | Fish Quality | Notes |
|---|---|---|---|
| Common (any) | Slow | Basic fish | Delete after hour 1 |
Common Strategy
Buy Commons to fill your starting slots. Watch them fish for 30 minutes. Use that cash to buy Rare+ eggs. Delete Commons as you hatch better brainrots.
Never upgrade a Common. Never keep a Common past the first hour. They're stepping stones, not destinations.
Special Variants Explained
Beyond base rarity, brainrots can have special variants:
Rainbow
- Boosted base stats (roughly +20%)
- Same rarity fishing speed, better output
- Rare drop from any egg
- Worth keeping regardless of base rarity
Golden
- Cash bonus per fish caught (+10-25%)
- Stacks with upgrades
- Rare drop from any egg
- Prioritize upgrading these
Event Exclusives
- Unique abilities or passives
- Limited availability
- Often match or exceed their rarity tier
- The Grinch, holiday brainrots, etc.
Egg Hunting Priority
Based on this tier list, here's what eggs to target:
| Priority | Egg Type | Why |
|---|---|---|
| 1 | Mythic | Best brainrots, worth any wait |
| 2 | Legendary | Realistic endgame goal |
| 3 | Epic | Mid-game army building |
| 4 | Rare | Early-mid transition |
| 5 | Uncommon | Only if desperate |
| 6 | Common | First 30 minutes only |
The conveyor shows timers for rare eggs. Camp those timers. A Legendary egg is worth waiting 20 minutes. A Common egg is never worth buying after the first hour.
Upgrade Priority by Tier
Where to spend your cash:
- Mythic brainrots - Max these immediately
- Legendary brainrots - Second priority
- Golden variants - The cash bonus scales with upgrades
- Epic brainrots - Your main income source mid-game
- Rainbow variants - Better base stats = better scaling
- Everything else - Don't bother
Spreading upgrades evenly is a trap. Focus fire on your best brainrots.
Income Comparison
Rough income estimates at max level:
| Tier | Income/Minute | Relative Value |
|---|---|---|
| Mythic | 50,000+ | 10x |
| Legendary | 20,000 | 4x |
| Epic | 8,000 | 1.6x |
| Rare | 5,000 | 1x |
| Uncommon | 2,500 | 0.5x |
| Common | 1,000 | 0.2x |
These numbers vary based on upgrades, Fish Index bonuses, and rebirth multipliers. But the ratios stay roughly the same.
One Mythic = Two Legendaries = Five Epics = Ten Rares
Plan your base composition accordingly.
Base Composition Guide
Optimal setups by game stage:
Early Game (Pre-Rebirth 1)
- Fill all slots with whatever you can hatch
- Replace Commons → Uncommons → Rares as you get them
- Target 4+ Epics before first rebirth
Mid Game (Rebirth 1-3)
- Minimum 6 Epics
- 2+ Legendaries
- Replace remaining Rares with Epics
- Save for Legendary eggs only
Late Game (Rebirth 4+)
- All Legendary or higher
- Chase Mythic eggs
- Max upgrade everything
- Golden/Rainbow variants prioritized
Endgame
- Full Mythic lineup (the dream)
- All max level
- Rainbow/Golden variants where possible
- Fish Index completed
Common Mistakes
Things I see new players do wrong:
- Keeping Commons too long - Delete them after hour 1
- Upgrading low-tier brainrots - Focus on your best
- Ignoring Golden variants - The cash bonus is huge
- Chasing Mythics too early - Build Epic army first
- Deleting Rainbow variants - Keep these regardless of rarity
