This is the Cook Islands Helfrichi Firefish. Yes, deep water. They assume this specific fish comes from deeper waters than the regular helfrichi and so loses the yellow on its head. Not a lighting issue in the tank but it is a VERY rare fish to find. Often in the 4 digit numbers.
The reason why you haven’t seen a helfrichi in the 4 digit numbers is most likely due to the deep water one being VERY rare and you only see the common yellow headed helfrichis (The “shallow” water helfrichi). The deep water variation is the purple headed helfrichi. The common yellow heads are from the Phillipines and the rarer purple heads are from the Cook Islands.I've never seen they being at 4 digit... According to quality marine, there's a deepwater var. also the reef builders pics are purple headed type. Beautiful fish.
Actually, I now see it, the first photo Quality Marine has looks more blue than the one Reef Builders has. Wonder if that is just the variation in the species/lighting or if that’s a completely different fish.I think they misplaced the picture in the pic above. Maybe they don't have the pic of purple one
