And unfortunately, very commonly dies in our tanks.
Needs long (typically 4 hours) acclimation to a mature (min 6 month old) reef tank using a drip method. Water conditions must be pristine, esp specific gravity, which should be 1.025-1.026. These stars require a minimum of 100lbs of LR, and I would propose that is marginal, ideally in a tank at least 100g.
They tend to die of acclimation shock within a month - watch for patchiness at the tips of the arms, disintegration, and "melting." I see most at our local LFS in this condition.
The rest typically die in a year or so, of starvation, with rather few making it past 18 months in captivity (the point where people can claim "success").
This is a very difficult star to keep, even if it is very small. I can not in general be spot fed, and requires very mature live rock - and lots of it - on which to feed.
