The fish in the photos is the exact fish you receive when you order.
Koi fish feature scales.
Fish develop their scales at a young age. Once they're done, they'll just keep becoming bigger as the fish does. Transparent scales overlap one another. Koi fish can have abnormally huge (dositu scales), tiny, or even no scales (leather Skin), depending on the type. They may also have a lot of reflection. Easy to see koi in the pond with lustre and sheen in the sun.
