A young koi is about 3-7 inches. when they grow to adulthood, they can as long as 40 inches!
Koi are a large growing fish (I've seen them at over 50cm long) and so they require a pond not an aquarium. They are also quite expensive. Koi are not for the beginner.

A Koi should grow around 6 to 8 inches long in its first year. By age 3 it should be about 24 inches long. I guess that's a reasonable growth rate
Koi is a type of fish. Just don't put koi in the pond and it will not be a koi pond.
If the Koi is large enough it may well eat a goldfish fry but Goldfish and Koi are not fighting type fish so they do not normally bite one another.
The plural of koi, a Japanese karp, is koi.
