As I mention on the previous part. These colorful fishes are very friendly, they surely come around whenever people around,
and they are ALWAYS hungry! No matter how many times you feed them, they’ll grab it all.
That’s why you have to be careful not to overfeed them. Because a tournament level fish, must have a torpedo like body (they cannot be too fat!).
The fish will have good colors and appearance if thes pond is well maintain, enough oxygen supply, a well operated water filter and of course good nutrition. So never throw any of your food into a koi pond, if the owner see you, you might get into trouble :)
A good Koi fish worth a fortune, especially the one that has won a tournament, its value will be doubled or even multiplied even more.
So how to identify a good qualifying Koi fish? A good koi fish have a good pattern (Kiwa), its pattern must be solid in color and well balance.
But, just like an art, fish collectors may have their favorite one, even though it’s not a tournament level fish.
Just like my late dad favourite one:
Look at the circled one below, the heart shaped Tancho kohaku. A very rare pattern on a fish.
