These came from Kwajalein. Which is the largest island in the chain of Marshall Islands from what I understand. I had never heard of that island before I got these guys. Anyway, I have owned SI chrysopterus a few times before I lost them to various shipping stress. Almost all of the Solomon chrys have black pectoral fins. Unfortunately, most from this locale(Marshall Islands) seem to lose their brilliant colors when kept in captivity. I'm hoping the natural sunlight this tank recieves might sustain their natural brilliance
For the record, S.I. Chrysopterus are the most beautiful clowns out there!
