Ok, I really don’t understand why are Acan frags so freaking expensive! I have kept them and they grow really fast for me!
Anywho, I found this on Pacific East Aquaculture and man is this a gem!
And $89 price tag for a frag of this size- 12 heads, is a steal~

If you have never kept Acan, here are some tips:
Water quality- the usual reef parameter- no trace of nitrate.
Water Temperature, I would say that the polyps and tentacles expands the best when it’s slightly cooler at around 75-77
Calcium- it is a large polyp stony coral so you need adequate amount of it
Light- T-5 seems to be the universally best light source. If you use LED or Metal Halide, make sure to place them medium to bottom. The color will become very light and eventually bleach out when there is too much light. They can actually do pretty well in dimmer condition because you can also supplement their energy by spot feeding- I’ve used a turkey baster to feed them grind up shrimp, mysis shrimp, spiraling enhanced brine shrimp, etc.
One word of warning, do not put them on sand, especially if you have something in your tank who likes to stir up the sand, they get irritated by sand quite easily.
