It looks just like my Red Thorny Star that I asked about not to long ago, except I got bashed for asking about it. Anyway here is what I know The Red Thorny Sea Star (Echinaster sentus) is in the Echinaster genus and will have similar behaviors and requirements to others in the same genus. In general, they are very peaceful and easy to keep. They do prefer a sandy substrate as well as a lot of live rock to pick algae and detritus from.
These creatures are natural predators of sponges, clams, and smaller anemones so use caution when adding one to your aquarium. Like most other Sea Stars they are very intolerant to sudden or changes in pH, temperature, salinity, and alkalinity and will not do well with high levels of nitrate. It can get to about 3" or so.
I hope this helps.
