How big would a koi grow in a 50 gallon?

Answer 1

if its a hexagon, commonly 23" x 20" x 24"

exact measurements may vary slightly depending on the manufacturer due to glass thickness and whether they measure the inside of the tank or the outside of the tank.

Answer 2

if its rectangular, often 36" x 18" x 18"

if its a bow front, often 36" x 18" x 20"

measurements are length x width x height in inches

exact measurements may vary slightly depending on the manufacturer due to glass thickness and whether they measure the inside of the tank or the outside of the tank.

Answer 3

Koi are not aquarium fish. A 50 gallon tank is like a puddle to a Koi and it would be totally unsuitable for just 1 fish. Koi were bred (developed) in Japan to be viewed from above in a pond situation they grow to over 2 feet long and have very broad colourful backs for this purpose. If you wish to keep a coldwater, carp type fish, how about you get Goldfish? You could house up to 4 of those in a 50 gallon tank.

Answer 4

if its a 20 gallon tall, commonly 24" x 12" x 16

if its a 20 gallon extra tall, commonly 20" x 10" x 24"

if its a 20 gallon Long, commonly 30" x 12" x 13"

measurements are length x width x height in inches

exact measurements may vary slightly depending on the manufacturer due to glass thickness and whether they measure the inside of the tank or the outside of the tank.
