Hump Day Koi Fix – Cool Koi Facts | Carters Nursery, Pond & Patio | Jackson, TN

It’s Wednesday, AKA: Hump Day! The day of the week that I like to blog about Koi. I have spent a lot of time lately blogging about Koi colors & markings and different varieties, etc… Today how about some fun facts… –

Some of my Koi. The Big Sanke in the middle of the pack – right below the Koi with the yellow ‘Ki’ head) is named Jaws 🙂 I got him when he was 15 years old. He lived another 15 years in my Pond and died at the age of 30 or so. A Koi breeder told me thats probably a good average age for a domestic Koi in a backyard Water Garden. | Carters Nursery, Pond & Patio | Jackson, TN


10 Cool Koi Facts –

1- Did you know that Koi and Goldfish aren’t the same species? Koi are descendants of common Carp and weren’t selectively bred until the 1800’s.
2- Goldfish were bred for their beauty and were prized by collectors 100’s of years before Koi were developed.
3- Koi were originally used as a food source. They were originally brought to Japan for this sole purpose.
4- Koi get MUCH larger than Goldfish! The largest measured/recorded Koi was 4 feet in length & weighed over 90 pounds! WOW!

WOW! This is a HUGE Koi! Koi can grow up to 48″ in length and weigh over 50+ pounds…

5- Koi can live a LONG time! The oldest recorded Koi was named ‘Hanako’, (pronounced han-nah-koh) which means ‘Flower Maid’ in Japanese. Hanako lived to be 226 years old! WOW!

6- The aquatic plants in your Koi Pond not only look beautiful and provide natural habitat, they help provide much needed SHADE! Koi sunburn badly!
7- Koi LOVE different foods! Try feeding them lettuce, peas, watermelon and oranges!

It’s time to feed the fish 🙂 Try something different. Koi LOVE fresh fruit and veggies too!

8- We love them for their bright,beautiful colors, but, their colors make them a target for predators like Herons and other birds of prey. Install a ‘Fish Cave’ to give them a place to hide from danger.
9- One female Koi can lay as many as 50,000 eggs during a breeding season! Up to 50% can hatch… WOW! That’s a LOT of babies!
10- Koi are intelligent and trainable! You can easily train your koi to eat from your hand and to ring a bell for a treat! Prety Cool!


I LOVE learning more about my finned friends and I hope you do too!

Happy Pondering! and Merry Christmas!🎄

PS: Koi make a wonderful gift! 🎅🏻

WHAT is a Fish Cave & WHY do I need one? | Carters Nursery, Pond & Patio | Jackson, TN

I recently did a blog titled – HOW TO DEAL WITH PREDATORS IN KOI PONDS where I covered several ways to combat Pond Predators – Like Blue Heron, Egrets, Raccoons, etc.

It was a very popular Blog! And it lead to several calls & conversations about this subject. The #1 question I discussed was ‘How-To’ make a Fish Cave aka; a KOI CAVE. So lets revisit this subject for a moment.

A  “Fish Cave or Koi Cave” is usually pre-designed and is normally part of the initial install of the Pond. It entails building a ledge or cave within the stone work of the pond walls to give the fish a place to hide from predators or to get out of hot sunlight for a while. Now if you already have a pond and want a fish cave – it’s really not a big problem! A fish cave is a common addition during your yearly Pond Clean-out. We add these quite often, so if your thinking you want to add a fish cave, it’s not a big deal.

This is an example of a “Koi Cave” that was pre-designed and built into the stone work. Beautiful as well as functional. | Carters Nursery, Pond & Patio | Jackson, TN

For those that don’t want to go all the way with a Fish/Koi Cave, there is an easy add-on product that you can purchase and simply submerge in your Pond. It’s called a “Koi Castle”.

A Koi Castle is an easy to install protector for you pond fish. It will provide them cover from Pond Predators! We stock these at Carters Nursery, Pond & Patio | Jackson, TN

I think that pretty much covers what a Koi Cave is. Some are very elaborate and some are simply a big ledge rock but they all provide cover and protection for your ‘finned friends’! You are welcome to come by the nursery during business hours to see both of these products in action. We actually have Fish Caves in one of our display ponds as well as Koi Castles in 2 of our displays. They both work very well and have protected our fish for years.

Happy Pondering!
