How to Obtain Koi in Grow a Garden
Go to a trusted GAG pet trading market, find a player who has Koi, leave a message, and wait for a reply.
The Koi is a Mythical pet that was obtainable during the Zen Event, through the Zen Event Shop (Tranquil Treasure Shop). It is designed to be purchasable with Zen Event currency (Chi) or, alternatively, via Robux purchases if players choose to skip the event grind. The official cost is 45 Chi or 449 Robux. Now, Koi is unavailable through the current Grow a Garden Event. If you're looking for a Koi pet for a lucky egg harvest, you may want to go visit one or two pet trading markets. On TradeKitsune, there are thousands of Koi pet offers available on these two trading sites currently.

Grow a Garden Koi Trade Value
The Koi’s price in the Zen Event Shop is 45 Chi or 449 Robux and its current sheckle value is around 30 Sx. Players should note that the Koi's value is not stable. The price goes up and down based on the Koi pet offers and requests on the market.
The Koi's sheckle value grows 10 times from August 21 to October 31 and here are two major reasons:
1. More Koi Requests from late August.
Koi has a very useful skill that makes it a trending pet in the garden. When you sell trash pets, there are chances to get lucky pet eggs for free. The egg recovery chances goes up with your Koi's weight.
2. Sheckles Fluctuation
For example, an 8kg Bronto value is about 10M sheckles in the in-game trading system; however, its current trading value could be more than 200 Sx (sheckles).

Koi FAQs
Q: What is the Koi in Grow a Garden?
The Koi is a mythical pet introduced during the Zen Event. It resembles a decorative Japanese koi fish and is known for its aesthetic appeal and strategic usefulness in the game.
Q: How do I get the Koi pet?
- Koi can be purchased from the Zen Shop.
- To unlock this shop item, you must upgrade the Zen Tree to level 4 or higher.
- The cost is 45 Chi (event currency) or 449 Robux if buying with real money.
Q: What is the Koi’s passive ability?
The Koi’s ability is called "Fish of Fortune". It gives a small chance (~0.61%, up to about 1% with improvements) to return an egg after hatching. This makes it especially useful for players who hatch many eggs, saving resources over time.
Q: What does the Koi eat and how much hunger does it have?
The Koi has a hunger value of 2,500, which is relatively low. It can be fed mid-priced fruits like corn, raspberries, coconut, or avocado. There's no need to feed expensive fruit since Koi doesn’t gain extra effects from them.
Q: How to maximize the Koi’s effect?
- Place multiple Koi pets in your garden to increase the chance of egg return.
- Keep Koi close to eggs to not miss the egg return chance.
- Combine with pets like Rooster (increases hatching speed) or Ostrich (ages pets), for better efficiency.
Q: Is it worth using Koi on all eggs?
It’s best used with ordinary eggs since the egg return chance does not apply to exotic or premium eggs.
