    Always had the "cute little starfish" and have never thought of them as being a bother until recently.
    Just got some zoas from Bill (rings of Jupiter and tubbs blues) and was paying attention to the tubbs after the rings of Jupiter disappeared - noticed that this starfish was on what remained of the colony for an extended period of time:

    This one is gone from the tank but I have hundreds.  They seem to bother newer/smaller zoas which may explain why I've had problems in the past.
    I've read that a harlequin shrimp may help but it's hit-or-miss.

    yeah thats all those shrimp eat, so if you get one you need to think about what to do with it after your problem is gone.

    A concern is what to do after the stars are gone.
    Granted, I most likely have a hundred in my tank, but if this shrimp's sole diet is as a predator of stars then it may not take that long to run out of food.
    That and I would need to see one actually eat a star prior to purchase.

    I think the problem with these stars is when their numbers get too high in a tank.......I have seen them on zoa polyps as well. I read an article on them just recently, I think it was from a link someone posted on here. Supposedly when all the legs are of equal length, they split to form another starfish. I've been manually removing them every other day or so and have noticed they are much harder to spot now, so I think you can keep up with them if you keep picking them out.

    eric what some people do is put a starfish in their sump and whack of a leg to feed the shrimp from time to time. What I have found in my tank and these stars is they tend to boom one day and die out the next. depending on how much food there is to eat they control their own population. But that is my tank and as we all know what is true for one person is not always so for the next.

    Hey eric...just get a shrimp from Hung. 2 of them went thru almost 200 of those little stars in 3 months. Then I would buy a cheap chocolate chip star fish to keep them fed. By the time they finished the cc they had a handful of the little ones again...plus they're kind of cool to watch.

    Eric - I was at Sea of Marvel last weekend and Hung had 2 Harlequins. You might give him a call and see if he still has them. They are SO cool looking.

    They are so easy to just pick out. I'd do that.

    I used a turkey baster and sucked them up 20-30 at a time. It takes 5-10 minutes to suck that many. Quick and easy.

    They ate several zoas in my tank when I first noticed them.Read that they eat zoas and other corals as well as coraline algae so I eliminated mine quickly by hand picking or using the turkey baster.Both work.They feed mostly at night so wait a couple of hours after lights out then get a small LED flashlight and gitr done!
