Cons: Some have a high price tag.
Acanthastrea Lordhowensis comes in literally a rainbow of colors. The color of the coral may change depending on the lighting it's in.
It has a very fast growth rate and has been known to grow a new head almost weekly while being fed meaty foods (mysis, brine, etc).
They're very easy to frag (dremel, chisel, razor, etc) and can almost mutilated during the fragging process and still make a full recovery to both mother colony and frag.
It has very short tentacles and doesn't seem to be an aggressive coral; in fact, they often seem to be the "loser" when it comes to a coral-conflict.
They tend to enjoy lower flow and lighting, but they can be slowly acclimated to a large variety of conditions.
They have been known to be a little "pricey" for some of the more interesting colors. The high price tag may be worth it because the coral is able to grow and multiply quickly.
