five species of siganus used to be under the lo. genus, but is since considered more of a "sub genus" for siganus. however, people just use it interchangeably in colloquial terms. i don't believe i'm wrong, but i love learning about these things.Your post popped up after I posted mine,so you saying foxface didn't used to be a rabbit fish ? But now is classed as one ?
Sorry late here and brain not working as good lol
