I've had 2 Mccosker Flasher Wrasse in my 110gal for probably 4 months now and they have gotten along (aside from flashing) for the most part. Never saw any physical damage and no evidence of stress. When the bigger wrasse flashes they kinda just swirl around each other and then go off their separate ways. My main problem with these 2 I feel was that my older wrasse was in the tank for probably 6 months before adding the second and it's pretty large although doesn't have the coloration or long filament of a male. The second wrasse was definitely smaller but it had the coloration and filament of a male wrasse. It was also clear to see the larger although not apparently male wrasse was dominating the smaller. Again I never noticed any physical damage or stress. Both eat very well and are extremely active in my tank.
However today...my smaller male Mccoskers fins are shredded and filament is gone. I'm really shocked by this because it seems to have happened out of nowhere. It's still eating and acting normal but everything I read said that they would be ok together. I'm hoping that the size difference and possible role reversal didn't cause this issue. I haven't changed or added anything new yet as my Anthias is still in QT so my finger is only pointing to this other wrasse.
When the wrasse go to bed I'll catch the smaller and put him in QT. I know where he sleeps lol.
