not necessarily a Silk mix, but definitely a Pearly ZZ. Indo ZZs back in the days look like this and also King Lais from VN. Also some USA breeds from hobbyist can be like this also. But a lot of FHs from different breeders can look alike because they are all withing the FH breedings and lines.
These days one fish can have alot of traits of wether you call ZZ kamfa or Malau or Kings or Rainbows. Sometimes a fish can have all the traits. Doesnt mean it's gonna look lgood, but you get those and what do you say?
