I dont know much about starfish at all. I was setting up a Bandensis tank and my live rock produced a colony of about 10 asternia stars. All are about 1/4 inch across. I know they are usually safe for a reef tank, but did not know about a cuttlefish tank. They are eating algae and there is a surplus of it. Any reply is appreciated. Thank you.
