How many scales does a koi fish have?

It's impossible to give an exact number for how many scales a koi fish has. Here's why:

* Species Variation: Koi fish are a variety of carp, and different carp species have different scales.

* Individual Differences: Even within the same species, individual koi fish can have a varying number of scales due to genetics and growth.

* Scale Types: Koi can have different types of scales (metallic, mirror, etc.) which can affect the overall count.

However, you can say that koi fish generally have hundreds to thousands of scales covering their bodies.
