    Predatory Starfish

    Has anyone had any experience with predatory starfish ?

    I've been experiencing an increasing number of white patches all over my liverock and believe I have a predatory starfish problem. I've noticed these small starfish since day one but never paid much attention to them until I read this link

    http://www.garf.org/STAR/starfish.html

    I'm sure these are the cause of my problem and Ithink I have tons of them.... I removed about 8 along the glass in the last 2 days.

    This problem is only on the liverock and not on any of the powerheads that have coraline on them.

    I dunno, I'm not convinced by GARFs site. I have probably thousands of these starfish and they don't seem to be causing any problems with my corals. When I discovered the first ones about a year ago I posted a pic to Dr. Ron's forum on ReefCentral. He said that although there is a minority group of these that can be harmful to corals the vast majority of them aren't. I find them everywhere in my system but never on a coral.

    If these aren't the cause of my problem any idea what could be causing all the white patches on my liverock ? Calcium is at a good level....

    Do you have an urchin? I bought a diadema when my tank was about 6 months old and I started getting hair algae. He does eat some coralline now and I see white areas on the rocks in the morning so I know where he's been the night before. However, in the long run he spreads more coralline than he eats and it's an excellent tradeoff considering I have no worries about hair algae.

    Even if it is the starfish eating coralline would that really be a problem?

    Good point Susan.
    Tuxedo urchins are voracious algae eaters, including coralline.

    I have tons of little white starfish, about 1/2 cm across. They haven't harmed a thing in over a year. I can see 10-20 at any one time in the tank.

    The only thing two reef keepers will agree on, is what the third reef keeper is doing wrong!
