These beauties are STUNNING in our new display tanks, which we are eager to continue filling! Did you know that Koi can grow anywhere from 12-36 inches long depending on the type of Koi in question? In fact the largest Koi on record was a 90lb, 4 foot long fish named Big Girl who was roughly 3 times the size of most other Koi!! While ours might not get to be that big, they do have plenty of room to grow!All pictures shown are for illustration purposes only. Actual products may vary due to natural variation with livestock.
