Koi Pet Guide — What You Need to Know
The Koi is one of those pets that immediately turns heads in the trading hub. Sitting at Legendary rarity with a base value of 580,000 Sheckles, it's ranked A tier — solidly above average. It's not the rarest thing out there, but it holds its value well in trades.
What Makes the Koi Special?
Every pet in Grow a Garden has a unique ability, and the Koi's is pretty interesting: Koi Pond - +2x value to pond plants. This ability affects how you play around this pet. Whether you're using it for farming, trading, or just having it in your collection, knowing how its ability works gives you an edge.
What really sets the Koi apart is its Legendary rarity. Legendary pets are the backbone of the high-tier trading scene. Everyone wants them, and they hold their value well.
Weight Progression & What It Means for You
The Koi hatches at 400 kg and grows at 1 kg per age level. That growth rate is steady. It's not going to skyrocket overnight, but with consistent farming you'll see your pet's weight climb over time.
Here's the weight breakdown that actually matters for your wallet:
- Standard (0–4999 kg) — 1x value. This is where every fresh-hatched Koi starts.
- Huge (5000+ kg) — 2x value. This is a serious grind. You're looking at weeks of active farming to hit this threshold.
- Titanic (15000+ kg) — 5x value. A Titanic {pet.name} is rare and commands respect in any trade negotiation.
- Godly (40000+ kg) — 15x value. The holy grail. A Godly {pet.name} is worth a fortune and barely anyone has one. If you're going for this, you're in for the long haul.
Not sure what age your pet needs to be to hit these thresholds? Use the pet weight calculator — punch in your Koi's current age and see exactly how many kg you need for the next class.
How to Get the Koi
You can currently get the Koi from Event. The hatch rate is low, so don't be discouraged if you don't get one right away — it's all RNG. Some players go hundreds of eggs without seeing one.If you're trying to hatch one, here's a tip: hatch in bulk. Opening 10-20 eggs at once instead of one at a time just feels better, even if the odds don't technically change. And if trading for it is more your speed, run the numbers through the pet value calculator first so you know exactly what it's worth.
Trading the Koi — What to Watch For
The Koi market in Grow a Garden moves around depending on updates and what the player base is hyped about at the time. Here are a few things I've learned from trading these:
- Weight class matters more than you think. Don't just look at the base value. A Godly Koi is worth 15x more than a fresh one. Always check the weight before you offer or accept.
- Rarity alone doesn't set the price. Two pets can both be Legendary but have very different values because of their ability, demand, and availability. The Koi's value is a mix of all these factors.
- Don't trade it in a hurry. High-tier pets like the Koi don't come around often. If someone's rushing you to accept a trade, that's usually a red flag. Take your time, check the value, and use the WFL trade checker to compare both sides.
- Know when to hold. If the game just dropped a new update, pet values can shift. Sometimes holding onto your Koi for an extra week pays off more than flipping it immediately.
Frequently Asked Questions
What's the Koi worth in Grow a Garden right now?
With a base value of 580,000 Sheckles, the actual trade value depends heavily on its weight class and any mutations. A Standard one goes for around 580,000 Sheckles, but a Godly one can fetch 8,700,000 Sheckles or more. Check the pet value calculator for a live estimate.
How rare is the Koi?
It hatches from Event at a low rate. You'll likely need to open dozens of eggs to get one.
Is the Koi good for farming?
It's decent. The main value of the Koi comes from its trade value rather than its farming ability, but you can still assign it to plots for passive XP.
Should I trade my Koi or keep it?
If you don't use it actively, there's an argument for trading it while the demand is high. But if you're into farming and its ability fits your setup, holding onto it might be more profitable in the long run. Run your trade through the WFL checker and see if the offer makes sense.
