Mixing wrasses

[Ryan]

How are fairy wrasses? I recently purchased a McCosker and want to add 3 or 4 more in a 75G. Was also thinking of adding a trio of Blue Flashers.

I had this McCosker in a tank with the Blue FLasher at work and they were fine for days, then I bought the McCosker. Maybe it was just these 2 fish I am not sure.

If a 75 wont work for the 2 species or even for the small group of McCoskers what would be the recomended size? 150G?
