The Phantom Clownfish is jet black with jagged white snowflake markings. These will have less white on them as compared to the premiums and ultras. Early juvenile fish are often dark brown, but turns jet black when they reach a size of 1.25 -1.5 inches.
As with most black clownfish, the black develops fully as the fish ages and matures. Early on it can have some orange mixed in, usually around the face. This will go away in time.
