🎣 How to Catch the Rainbow Fish
Step-by-Step Guide
Reach Fishing Level 10
The Rainbow Fish requires the maximum fishing level. Keep fishing regularly and complete fishing-related quests to level up.
Wait for Rainbow Weather
Open your Watch and check the weather forecast daily. Look for the 🌈 rainbow icon. Rainbow weather typically appears after rain clears.
Travel to Starlight Sea
Head to the Starlight Sea fishing spot. This is the only location where the Rainbow Fish spawns.
Cast Your Line
Hold the input button to aim your cast directly at a fish shadow. This speeds up bite time. Watch for a large shadow — that's likely a rare fish.
Manage Line Tension
The Rainbow Fish fights hard. Watch the tension indicator — release when it flashes red to prevent the line from snapping, then reel in when it calms down.
⚠️ Important: Rainbow weather is rare and time-limited. When it appears, drop everything and head to Starlight Sea immediately. You may not get another chance for several in-game days.
🌈 Rainbow Weather Explained
Rainbow weather is a special weather event in Heartopia that unlocks exclusive rare fish, including the Rainbow Fish. Here's what you need to know:
How to Check
Open your Watch and tap the weather icon in the top-right corner. The forecast shows upcoming weather, including rainbow days. You can see it the day before.
When It Appears
Rainbow weather typically occurs after rain clears. It's random and not guaranteed on any specific day. Check your calendar daily so you don't miss it.
Rainbow Blessing Buff
During rainbow weather, you receive a Rainbow Blessing buff (shown near your minimap). This grants extra resources while collecting and boosts your chances for higher quality catches.
Doris the Traveling Vendor
The NPC Doris only appears during Rainbow weather events. She sells unique items not available elsewhere. Look for her at Onsen Mountain or near the town.
Other Fish That Require Rainbow Weather

💰 Rainbow Fish Sell Price & Star Ratings
The Rainbow Fish has a base sell price of 5,000 Gold. Since it requires Fishing Level 10, you'll always have access to 5-star catches. Star ratings dramatically multiply the sell value:
| Star Rating | Multiplier | Sell Price | Notes |
|---|---|---|---|
| ★ | 1x | 5,000G | Base price |
| ★★ | 1.5x | 7,500G | — |

| ★★★★ | 4x | 20,000G | Unlocked at Lv4+ |
| ★★★★★ | 8x | 40,000G | Unlocked at Lv6+ |
💡 Pro tip: Since you need Level 10 to catch the Rainbow Fish, you already have access to 5-star catches. A single 5★ Rainbow Fish sells for a massive 40,000 Gold — the highest single-item sell value from fishing in the entire game.

💡 Rainbow Fish Catch Tips
Check Weather Daily
Open your Watch every day and check the weather forecast. Rainbow weather is shown the day before, giving you time to prepare.
Aim Your Cast
Hold the input button to aim directly at fish shadows. Don't just tap — holding and aiming speeds up the bite time significantly.
Watch Line Tension
The Rainbow Fish fights hard. When the tension indicator flashes red, release immediately. Reel in when it calms back down. Patience is key.
Use Bait
Scatter bait around the shoreline at Starlight Sea to draw more fish shadows. This increases your chances of encountering the Rainbow Fish.
Upgrade Your Rod
At Level 10, you can unlock the Pearl of Tides rod which gives +20% luck. Use the best rod available for the highest chance of catching rare fish.
No Time Limit
Unlike some rare fish, the Rainbow Fish has no time-of-day restriction. You can fish for it all day during Rainbow weather — focus your entire session on it.
✨ Make the Most of Rainbow Weather
Rainbow weather is rare, so maximize your time when it appears. Besides catching the Rainbow Fish, here's what else you can do:
Fish at Multiple Locations
After catching Rainbow Fish at Starlight Sea, visit Whale Sea for Swordfish and Gentle Wind Sea for Bluefin Tuna — both also require Rainbow weather.
Rainbow Blessing Buff
The Rainbow Blessing gives extra resources and boosts quality across all hobbies — not just fishing. Farm, catch bugs, and photograph birds too.
Visit Doris
The traveling vendor Doris appears only during Rainbow events. Find her at Onsen Mountain or near town for exclusive items.
Collect Rainbow Bouquets
Three Rainbow Bouquets spawn during the event. Collect them for bonus rewards as part of the special rainbow weather task.
