I could not really remember the black tang in CF in details. But I can be sure that the tang has the common stripes/pattern that is commonly found on scopas tang (I got a brown/scopas tnag from CF). Interesting, when I ask them on why the black tang has the stripes, they mention that some rare black tang does have them.
One thing for sure, it is definitely not as black as the one bro roidan has.
Sorry, I was not able to confirm much cause it is defintiely out of my budget. Spent on time on selecting my scopas tang.
