Yes, how about some tank specs?
Size
How old
How long have you had the star
What is the specific gravity, pH, ammonia, nitrite, etc levels
How much live rock do you have
How long was the star acclimated
This is a particularly delicate star, and needs to be acclimated over 4+ hours. It can not be spot fed, and must have lots of LR in a large mature tank (100g+, IMO). They are well known for dying of starvation at the 1 year mark. They will die within a month (often a week) after introduction if not acclimated.
They will virtually dissolve, and with lots of crabs etc, it will be gone fast.
