Tang Question

[mindi]

I have a Tang in QT and it's a bit hard to photograph but will do so on transfer to DT.
I am uncertain because of the contradictory info on the web and the apparently careless use of "white cheeked", "white faced" "powder brown" etc etc..

This fish certainly has a white cheek patch under the eye which does not extend to the mouth, and a strong yellow vertical patch on the tail.... but I need guidance to positively distinguish Japonicus from Nigricans.

Is there a certain way to distinguish them..?

Japonicus... white goes all the way to the mouth.

Nigricans... just a little patch under the eye.

Google thanks you

I actually have never kept either fish. I always though nigricans was a very sleek looking tang though.

Thanks everyone..it is Nigricans without doubt. What a beautiful fish. I thougfht that was the case but found the colour descriptions a little confusing.
