So @i cant think picture that reef2reef used on Facebook is indeed a yellow corris and not a banana?The confusion by hobbyists and even fish stores between female banana wrasse & yellow coris wrasse is more common than I thought. The following is just a quick research from the internet and there are already quite a few places that prominently display yellow coris as female banana wrasse yet have the right scientific name, Thalassoma lutescens.
The pic from liveaquaria is the right one. The one from tankfacts.com is not factual as the dots on the dorsal fins are clear indication of yellow coris. MarineFishEz gives two pix where one is right and the other is wrong.
