What are these?

The darker clowns are almost half black, the bright orange are in the same tank. All labeled false percs. Simply a darker color?

To me, it looks like the blacker one looks like it is a true perc. It's kinda hard to tell with the picture; however, the number of dorsal fins can sometimes determine which they are. If there are 10, then it is a true. If there are 11, then it is a false perc.

Or it could very well be a darker false perc

I keep counting 10 and i have read that occasionally a false can have ten but never vice versa.

I counted 10 initially too. Are you planning on a pair of false percs?

Just a pair of clowns in general... I just dont want to get one thats an occy and one true percent. Im good with two having a variance of color though.
