Question on fairy compatibility:
I have a long-established red velvet fairy wrasse, about 4 - 4.5" long, as well as a smaller (~3.5") exquisite fairy in a 260 FOWLR. They have no issues with each other. My LFS has a gorgeous Australian Scott's fairy wrasse that is really tempting me. It is a big boy - about 5 or 5.5" - as large a fairy as I've seen - and eating well. I have a social acclimation box I can use for a day or two to facilitate the introduction, but is this just a bad idea regardless, or if done properly are they likely to make peace, or at least reach a detente?
LFS also has a good-sized McCoskers I was considering. I've never kept a flasher wrasse before, but will they mix okay with fairies? Will they flash in the presence of fairies, or do you need a harem of flashers for that to happen?
