My Starcki damsels all still have their yellow. They are all from the the South Pacific, either Australia, Melanesia or Polynesia.
The ones from the northern distribution, Indonesia, Philippines, Micronesia,... are most likely a separate species.
This might be a reason for the varying experiences with them.
Also, genetic analysis has shown that starckii (northern or southern) are not at all closely related to the genus Chryspitera which they currently placed in. Their closest relative is a fairly unsightly Damselfish from the tropical East Pacific.
