Need help identifying

[ReefMaster101]

Hi just found this in my tank. It's smaller than a dime and has brown spikes on the top and a star pattern on the back. If anyone can help me identify it would be great.

Are you sure it's alive?
It looks like a sand dollar to me.

Be careful of the orange and white thing in your tank. They bite.

Im also going with sand dollar. Cant tell if its alive from the photo. You can see that it has 5 "sections" (looks like an asteric almost *) radiating from the middle. Classic echinoderm morphology
