NO Linckia should be considered "EASY" to keep under any circumstances!!!!!
That is definitely not true, IMO.
They need a large, established tank with pristine water parameters, long acclimation and loads of LR for best results. This is not to say there are not EXCEPTIONS to this, but the fact is that most Linckia will die either of acclimation shock of of starvation within a year. Don't count on getting the exception.
I wrote a piece on these animals in the archive section:

Seastars Part 1 is specific to Linckia sp. stars.
You should start with listing your tank parameters, age, etc, etc to determine if you have the minimums.
