How do you tell the difference

[joesanzone]

between a False Percula & a True Percula?
I'm considering adding one or a pair to my 75 gal w/ a Kole Tang & a six line wrasse.

This is from this website in their live fish section. This is a false perc.

This is a true perc.

True percula has thicker black bands.
