Thanks for your help, Laurence, and now I am back the web.
Raymond,
Whipfin Fairy Wrasse (Cirrhilabrus filamentosus) vs Carpenter's Flasher Wrasse are shown here. They belong to two different genera, but some similarities are seen. Yes, both species have filaments on dorsal fin; one (rarely two) in C. filamentosus and two to four in P. carpenteri.
Young males or females may become males, but usually one of them will do if it will happen, and the rest will stay females. However, I experienced two out of five of flashers became males eventually, but one of them became larger and another rather smaller.
females of C. filmentosus are reddish overall with several narrow lines on side, a white abdomen, a small black spot on caudal peduncle, and a white spot on upper lip. Those of P. carpenteri are red overall and whitish ventrally, with a white line on eye and several narrow black lines on side.
See the photos of males of the two species.
