I have a six line wrasse in my tank along with 3 firefish and 2 false perc clowns. The six line wrasse are very good community fish. The Six Liner is more active cruising the entire tank and does not bother the firefish at all. I think the firefish is a good choice
They will turn their bodies toward the current and give you a good view of their bodies and put on a good show. I stocked my false percs first, then the firefish and then the six liner.
