He's a marble. Not a koi (a koi has some specific colours which I don't remember). As to whether he is a king, we need to know his size... If he's 2 to 2,5 inch, then he's a king. If he's 3,5 to 4 inch, then he's a giant. (If I remember correctly 🤣 ) As to how old he is, I don't think there is a way to know. You could ask the pet store you got him from, but I don't know if they'll be able to give you an answer...

 

Thanks for commenting! I did post on another forum last night and they said he looks like a HMPK Marble King. Yeah age wise I’m thinking 8-12 months like most pet stores. I was just wanted to know how long I have him for. He’s a good little noodle!!! He’s coloring up a little more and his fins are less clamped now. He’s a great eater too!!! Also, it looks like he’s roughly around 2-2.5 inches.
