I googled the cyaneus and it does look like that. I'll try to snap a pic of it with all the fins displayed in the future as the fish might still be adjusting to the tank. It is just that I have never ever seen a cyaneus from all my trips to our local (Philippine) exporters.
Also on another topic, I have some question on how a flasher and fairy wrasse transitions or changes into Alpha Supermale. First, does a single individual transform into an alpha super male on its own or do they need females of the same specie or just lookalike females? Secondly, do existing alpha supermale (I have a cf. pintail one) stop this transition and keeps all the others at submale/female EVEN if they are not of the same exact species?
