I had a Blue Linckia for 23 months, did notice it eating some black sponge. Problem there was it clean the patches off and the sponge never grew back.

Thats the answer! Most of the "reef safe stars" Blue, red, orange, are sponge eaters, I have had a blue for about a year now and it makes it's way around from rock to rock eating the multipule colored encrusting sponges that grow in my live rock "Purple, yellow, pink,black and white sponge" but I have noticed that over the last couple of months the sponge colonies haven't been able to grow back fast eanough to sustain the growth of the blue star. My tank is 300gal and after seeing this I would'nt recomend anyone keep these creatures unless you can aford to buy live sponge to feed it.
