Holy Grail Wrasse (Paracheilinus hemitaeniatus)- Single Jumbo MaleHoly Grail Wrasse Paracheilinus hemitaeniatus, the half banded flasher wrasse is a very elusive species that has been all but absent in the aquarium hobby. Hailing only from Madagascar and a few locations in South Africa, this species has turned out to be the holy grail for this genus, at least as far as the Indian Ocean is concerned. This is the rarest species within this genus. Extremely rare and very hard to come by! Stunning Jumbo Male.
