What is wrong with my Star?

So i noticed yesterday that my sand sifting star looks to be falling apart or is being eaten by something. The star is acting normal and moving around as much as usual. I just don't know what is going on with it. Any advice?

From my reading on them;
Most aquariums don't have big enough sand beds to support them in the long term as they can decimate the fauna in a live sandbed and as a result starve to death.

It is not being eaten most likely...though perhaps be scavengers.,
Nearly all of these stars will die in captivity of starvation.
What size is your tank?
What are your specific parameters?
I've you've had it a month, it may be acclimation shock.
If you've had it 6 months or longer (esp a year) it is very likely starvation. They basically start to "disintegrate" and arms fall off until it is basically just gone.l
They usually only survive long term in very large tanks with very mature deep sand beds.

ok so thanks for the info. With everything else I have read it definatly sounds like starvation. So my next question is should I let it die or get rid of it before it does. I have had it over a year so I thought I was in the clear but I guess not. I hate learning this way.

12 to 18 months is probably the peak of starvation deaths :(
Probably if you have crabs and such they will take care of it. How big is the tank?

If you watch water quality closely, I imagine you will be fine.
Offhand, have you ever tried spot feeding it? Something like a small bit of shrimp on a bamboo skewer, touched to the arms to see if it will take it? Few do, but it is worth trying.
If you want to "put it down" I can give you tips. The best way for seastars is a reverse acclimation (put it in a bucket with a bit of saltwater and slowly add seawater). This effectively "relaxes" it.
Whenever I mention this I feel I must bring up Steinbeck, who actually refers to this in "sweet Thursday"

Doc got back from his collecting about four-thirty... and submerged in sea water in his collecting buckets were hundreds of brittlestars. He moved the brittlestars to a large, flat-bottomed glass dish and poured some sea water on top of them. The little animals with the snakelike arms whipped about for a moment and then settled down. When they were quite still and resting Doc added a little fresh water to the dish. The arms stirred nervously. He waited a while and then added a little more fresh water. To a sea animal, fresh water is a poison, and if it is slowly introduced it is as subtle as morphine. It relaxes and soothes until the little creature goes to sleep and dies without violence."

Oddly enough, to me this is one of the more beautiful passages I've encountered, specifically the last sentence, perhaps due to the compassion shown to "little creatures."
A similar effect can be achieved with Epsom salts. Put the star in a shallow dish with seawater and in a corner put a tablespoon or so of epsom salt. Every so often, tip the tray to dissolve some salt. It, too, is an effective "relaxant" and over time the star will stop moving.
