Some of my favorites, I've owned several throughout the years and generally have had good success with them. There are currently 7 in my tank and all are over 1 year old. Here are some general comments:
The aussie ones seem to fare much better based on my experience.
The longer the polyps, the more difficult they seem to be to keep alive long-term.
They seem to be very sensitive to water chemistry, even more so than acropora.
The really short polyped ones, almost encrusting, seem to be quite hardy.
Yours looks a bit bleached and the presence of green algae around the edges of the frag is concerning. I'd give it lower light and some flow but not strong flow. I've personally never seen them eat but it wouldn't hurt to try. Good luck!
