moonpod,
Thanks for info of your fish and tank. It is very hard to make them form a harem in a tank even if a group was captured in their natural habitat, and they will behave individually.
Your Paracheilinus octotaenia (Eight-line) would become a larger one soon and I hope it to flash someday. However, most of them will not excite when they are kept for some period, and it means that they settle down. I will add larger new specimens of other species or same one and then I expect that the old male would excite or even flash. Another way to see it flash is to change your tank circumstance totally or pick it up and move to another smaller tank, and add new specimens of the genus.
