Its a golden base king kamfa. Looks like one of mick kamfas fish I suggest looking for him on aquabid. He has ones like this for $200-400 regularly. Mickkamfa is his name I believe I had this fishes siblings for $25 a piece about a year ago.
Is this really Mick's fish? Looks like a Tan King mix...only Tan King have a unique tail pattern like that. I have yet seen any KK or Kamfa in general with that unique tail size and pattern with golden pearls. $1000 for this fish is base on the eye of the customer and what they think and feel about it that truly makes it worth it or not. But in my opinion, it's a little high but can be worth the price if it is confirm fertile. Other than that, $800 will be my top price I can go with if I'm buying this fish...very nice no doubt. Top grade...
