That's a really pretty one. At one point a few years ago, Acan lords (now Micromussa lordhowensis) were the 'in coral.' It seems like these things go in cycles. Euphyllia, of all things, seems to be hot in the last year or so, which seems crazy to me.
Acans are pretty easy to grow and frag too.
Price is so hard to nail down. It's so regional. Maybe 5-10 bucks a head? But maybe more, since it's more of a 'rainbow' type?
LPS folks might give you a better idea in that forum, compared to here in the SPS forum.
