wrasse advice

[Jsanders19]

Im in the process of adding more fish and am thinking about adding several fairy wrasses just looking for suggestions on which to get how many i should?

I currently have a marineland 300 gallon deep dimension tank, its a mixed reef trying to go more sps heavy in the future.

current livestock list:
Tangs:
1x Blue Tang (Paracanthurus hepatus)
1x Purple Tang (Zebrasoma Xanthurum)
1x Tomini Tang (Ctenochaetus tominiensis)
1x Naso Tang (Naso Literatus)
1x Clown Tang (Acanthurus Lineatus)
Wrasses:
1x Melanarus Wrasse (Halichoeres Melanarus)
Triggers:
1x Niger Trigger (Odonus Niger)
Anthias:
5x Lyretail Anthias (Pseudanthias Squamipinnis)
Clownfish:
2xOcellaris Clownfish (Amphiprion Ocellaris)

the wrasses i have been looking at to add are:
mystery wrasse (Pseudochellinus ocellatus)
Red velvet wrasse (Cirrhilabrus rubisquamis)
Exquisite fairy wrasse (Cirrhilabrus exquisitus)
Tricolor Fairy wrasse (Cirrhilabrus lubbocki)

I am open to suggestions for others. Also on another note I know these fish can change from female to male but when they are bought as males can they revert back in the absence of a female?

Skip that mystery wrasse. Terminal males of most species will keep 90% of their color; some species exceptions do apply.
