Sand Sifting Stars are one of the hobby's best detritus eaters. They sift through the bottom of your aquarium to consume much of the food and fish waste that accumulates there. This is not a sea star that you have to worry about adding to a reef aquarium. Add these into an aquarium with a little live rock and more sand to hide in during the day, and they will come out at night to do clean up. As they burrow in the sand, they turn the sand which oxygenates it. However, make sure the live rock is secure because this sea star can burrow under the rock, which can result in it toppling over. Even though these sea stars are excellent scavengers, their diet should be occasionally supplemented with finely chopped meaty items.
