Overview

The Sand Sifting Sea Star, at first glance, seems to be drably colored like most bottom dwellers. But closer inspection reveals a striking beauty and serenity to the alternating bands of brown and beige that dress this invertebrate's thick, spine-covered arms. Like other starfish, Astropecten polycanthus efficiently consumes mass amounts of detritus and uneaten foods. This nocturnally active member of the Astropectinidae family can move large amounts of sand as it burrows into the substrate in its search for food.

This peaceful omnivore will effectively clean even the largest home aquarium of detritus and left over food. Like other starfish, the Sand Sifting Sea Star will also consume small invertebrates, including shrimp, urchins, mollusks, bivalves, or other small sea stars. As such, the Sand Sifting Sea Star should be actively fed a varied diet consisting of natural food sources, especially in well-established marine aquariums. Otherwise, this voracious feeder will quickly clean your aquarium of detritus and then burrow into your substrate, starve, and eventually begin to decay.

To foster its feeding habits, the Sand Sifting Sea Star should be kept in aquariums with large, deep sand bottoms of several inches in depth. Since it is slower moving than most fish, the Sand Sifting Sea Star should not be housed with natural predators, including Puffers.

Like other invertebrates, the Sand Sifting Sea Star is very intolerant of sudden changes in oxygen levels, salinity, and pH and cannot tolerate copper-based medications. To successfully acclimate new specimens to your aquarium, use the drip acclimation method and never expose the Sand Sifting Sea Star to air while handling.

Breeding in the home aquarium is extremely difficult with no distinguishing characteristics to help differentiate between males and females.

Customer Testimonials

Ann Wlodarczyk Dearborn , MI

This little creature can really move! It keeps my sand turned and will readily eat any leftovers. It has not harassed any of my fish or inverts. It's fascinating to watch it dig itself into the sand for day.
Brent Loftis Wyandotte , MI
This starfish is hardy, fast, and perfect for cleaning up leftovers. It is safe for the most delicate of marine life, like seahorse fry. It will readily eat excess frozen baby brines shrimp and other frozen foods.
Raymond Watkins Greenwood , IL
This little guy is great. Mine dug himself into the substrate within a couple of minutes of being introduced to the tank. While I don't see a lot of him during the day, as soon as the lights go out and my moon lights kick on he is up on the substrate. And don't let their generally slow movement fool you - these little guys can get moving when they want to.
Todd Van Lom Hillsboro , OR
Great Star. Make sure you have a fairly deep sand bed to support its eating habits. Only recommend for an established tank. Personally, I have not had much luck feeding mine but it has done well on its own. Does a great job keeping your sand bed clean.
Kyle Schumann Waterville , OH
This guys are so fun to watch. They climb up the glass, burrow in the sand, and they move so much faster than I expected. They can really book! A great addition to any tank!
Garrett Escalon City Not Selected , CA
I love this sea star. My tank used to get a lot of the "brown algae" on the sand bed..and now that I got this sea star, I NEVER have that anymore..except the occasional "little brown spot". It makes the whole aquarium look better by cleaning the sand bed.
