I've had my sandsifter starfish for over a year and recently she has slowly been losing parts of her legs. I have a white ribbon eel, a yellow tang, and a long nosed halk fish. My tank just recovered from ick, and all the chemicals are normal. I also have corals that are doing fine. I've noticed that the starfish has not been burying itself in the sand as it used to do. she also moves much slower than she used to. Does anyone have any ideas on what could be killing her? I have not noticed any fish picking at her. Thank you for any help.
