Small butterfly koi in aquarium?

[Stefan3289]

I saw at my LFS that there were these small butterfly koi being sold that apparently only grow to be 3”-4” long. I have a 29 gallon tank and was wondering if I would be able to keep 3-5 of them in it?

Long-term, no.

I am not sure if maybe the 3-4” description was just their current size, but I feel that would make the most sense since I couldn’t imagine a koi reaching mature size at 4”...right?

 

[Stefan3289]

They however looked to be about 2” not including their tails.

Kois usually grow to about 12-15" in length. At 3-4," they're probably juveniles.

That would definitely make more sense sadly

I kept 3 rescued Koi in a 55 gallon tank for several years until I found someone with a Koi/goldfish pond and gave them to him. They do get big.

Ever seen a 3 foot koi?
