blood stained fairy wrasse.
Cirrhilabrus sanguineus
this was originally about to be described by randall. however, cornic stole the information and published it in his small book as C. sanguineus.
Randall was not credited and thus, he did not have the rights to name it. cornic named it sanguineus.
once a name has been placed, it cannot be changed. unless it has to be moved to a different genus etc.
