What is Koi worth?
Koi's money value is $12M/s at base weight with no mutation, and its rarity score is 64 (available). A mutation multiplies that value, up to $42M/s with Rainbow (x3.5); several mutations add up, and a heavier Koi is worth more.
Pets worth about the same: Wendigo ($15M/s), Citadel Snail #007 ($12.5M/s), Stacked Turtle ($12M/s), Mantaris ($11M/s).
There is no official value list: for a real offer, put it in the trade calculator, which tells you if the trade is a win, fair or a loss (W/F/L). Every pet's value: the value list.
