Recently my sandsifter has been deteriorating.
He has lost parts of two arms now and looks like losing more. Nothing has
been attacking him as far as i know.
Has anyone else seen this happen with theirs and should i get a small
coffin ready?

I found a discussion on ReefCentral about these kind of starfish
and the idea was that there is not enough food in the sand bed
in a small aquarium for these guys to survive long time... :-(
