Oscellaris or Perc?

[BCOrchidGuy]

True Percs have wider bands of black is another way to not know 100%, even counting fin spines isn't 100% one will have 11-13 and the other may have 12-14 on a fin. Price is always a good tell tale sign, a Perc will cost about 2-3 times the cost of an Occ, but that's assuming the pet store isn't trying to make more $$ off of you. True percs are pretty hard to come by.
