This is a female, transitioning male Paracheilinus mccoskeri. The way you can tell that appart from the carpenteri is the lines, on Carpenteri they have 2 middle lines between their 2 main lines marking the dorsal and lower line. Whilst Mccoskeri only has 1 middle line.Can someone ID this fish please.

Marjorie Fairy Wrasses are rarely seen in the hobby and also, Mccoskeri is not a fairy, instead it’s a Flasher.Fairy wrasse- Im thinking either Marjorie or Mccosker
Often males have higher fins and more vibrant colors. Im sure other traits but these are the ones I know ofFollowup question. This is a fairly new 90 gallon tank (4 months old) with the Mccoskeri, a Foxface and 2 saltwater mollies (who have already spawned in the tank) in it. It will be a predominantly softie tank.
I'd like to add a few more wrasses and am confused on the male/female mix. I'd read that you have to be careful with multiple males but is that male wrasses or male Paracheilinus? IE can I add a male Cirrhilabrus and a male Halichoeres or do I need to stick to female wrasses from here on out?
Ahhh- Flasher- yesMarjorie Fairy Wrasses are rarely seen in the hobby and also, Mccoskeri is not a fairy, instead it’s a Flasher.
Flasher wrasses are in the Paracheilinus genus whilst Fairy Wrasses are in the Cirrhilabrus genus. This is most certainly not a Cirrhilabrus species.
You can add males of other genera as well as males of different species that aren’t similar.Followup question.

honestly, in most species the males look like completely different fish to the females.Often males have higher fins and more vibrant colors. Im sure other traits but these are the ones I know of

I’d personally avoid Halichoeres chloropterus due to risk of aggression and also they don’t remain that vibrant green throughout their whole life, males supposedly go brown and white.Ones I've looked at so far are:
Cirrhilabrus scottorum
Cirrhilabrus Exquisitus
Cirrhilabrus Katoi
Paracheilinus Carpenteri
Halichoeres marginitus
Halichoeres Chrysus
Halichoeres chloropterus
My invert crews is currently various types of snails (wasn't planning on shrimp or crabs). Was thinking of breeding some feeder shrimp in my sump if needed.
Other fish that I'm looking to add down the road:
Marine Betta
2 Engineer gobies
Midas Blenny
Maybe a pair of clowns to play in my leathers but probably last
I’ve not had much personal experience with katoi but from what I’ve seen I have had a couple lucky specimens with around 3 nasty ones (I have cared for 5 total from what I remember) so definitely agree with avoiding them^^ agree, but I will recommend avoiding C. Katoi with flashers. I've had to remove a few belligerent Katoi's from client's tanks over the years.

Easier way of telling them apart is McCosker’s has one extended dorsal fin ray, Carpenters has 4This is a female, transitioning male Paracheilinus mccoskeri.

I've probably removed half a dozen over the years and a couple members of my reef club said theirs turned nasty after they became established. It's a shame because they're such a pretty wrasse.I’ve not had much personal experience with katoi but from what I’ve seen I have had a couple lucky specimens with around 3 nasty ones (I have cared for 5 total from what I remember) so definitely agree with avoiding them![]()
Actually this isn’t always true for 2 reasons;Easier way of telling them apart is McCosker’s has one extended dorsal fin ray, Carpenters has 4
It really is, I’m still waiting for the perfect wrasse but so far all the wrasses I’ve seen that I like follow the same pattern of aggressive tendencies.I've probably removed half a dozen over the years and a couple members of my reef club said theirs turned nasty after they became established.
