Koi in a 20g

[ElectricBlueSeanBurch]

Stop being a jerk and no, common sentence structure does not confuse me.

Wasn't being a jerk. Just elaborating. Simply stating you see a ton more koi in home aquaria from the 18"-4' range then the 4'+ range

He isn't even asking how big they get.

Stop being kids, and let's stick to the question.

If the water is cool, then you would be good for at least a half year. If the water is warm, then about 3 months of good care.

biggest i have seen a koi get is 2 MAYBE 2.5 foot...

Wow i see them all the time in the 2 foot range in ponds. 3 foot doesnt even get to be called uncommon. 4 foot is rare as most dont live 100 years in captivity.

I have a 3 ft plus koi in my pond and I believe they could reach larger sizes easily

To sum up this thread in a hundred years the koi will have vastly outgrown you 20g.

 

[livebearerfreak]

215 year old koi, 70 Cm-27 inches so a little over 2 foot.

Koi generally don't do well in small tanks, regardless of size. That 20g will last you 3 months, +- a month. Koi usually get to 2'.. I've seen smaller, and I've seen a 4 footer but 2 feet is normal.
