White Sand Starfish

[FitoPharmer]

The thing about sand sifting stars is they are not the best sandbed stirring CUC memeber you can get. IMO a sea cucumber or a small conch are much better options for a reef tanks sand bed. Sand stirring stars have a well known reputation of over cleaning sand, even in larger heavier stocked setups and dieing. And on the other hand they die if there is not enough food in the tank for it being understocked or a immature setup.
