a koi carp can grow as big as a pond
they grow bigg around 12 inches
a koi can live for hundreds of years if there maintained right. in that period of time they will grow 3 ft.
A young koi is about 3-7 inches. when they grow to adulthood, they can as long as 40 inches!
Provided there is sufficient water there.
Koi can live for hundreds of years in that period of time they will grow 3 ft. it just takes them a while to get there.
No, shubunkin fish will grow 9 to 18 inches long (23 to 41 centimetres). Koi can certainly grow 21 to 30 inches in length provided they are living in the right type of environment such as a large pond.
25-35 years
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
You don't. You put it in a pond. Koi grow to over 24". To keep one in a bowl would be terribly CRUEL!
It kinda matters. Mostly 25 inches, or more.
Duckweed can grow in any water that is good enough to sustain live fish.
