The store sold it to me as a black percula... but it only cost $20 and black percs are ususally upwards of $70

I had my nitrates spike and most of my fish die a few weeks ago. I've been doing water changes nearly every other day with RODI water and am now starting to introduce some heartier fish like clowns. This I want to pair this gal up with a smaller clown so that it will become the larger female... but I don't know if I can safely put it with a regular orange/white percula...? ...
