    Hey Guys
    I have an all of sudden bloom in Asterina Stars. Thwese are Blue/Grey in colour. Are they harmful to my tank and Corals? I am thinking of harvesting them with a small net as they climb onto the glass. I know it will not rid my tank of them but at least I can bring the numbers down.
    Main question right now is are they a hazard to my Corals and should I worry at this stage? Check out the pic's. This only the side glass. They on all the glass around the tank.


    Thanks
    M

    Did you acquire any LR recently ? You just missed some Harlequin Shrimps, they are great for keeping them under control.

    I must say it has been coming on for a while so I honestly don't know. Coming to think of it, I did acquire a small saucer size rock with button polyps and mushrooms on it. Maybe it was that but can't say for sure. I have a beautiful Orange Star Fish and don't want to risk loosing it to them Harle.quen Shrimps. I also have some Bristtle Stars.
    Check it out.

    The best is to remove the asterina stars physically, not sure what predators there are that eat but I will look for a link I had on my pc in the morning

    I have some. So far no issues. Some guys did report issues, so I do suspect that it is different types. Seeing yours are on the glass, eating away on the algae and diatoms, I would not worry about them.

    As long as they are not covering a coral, then you got nothing to worry about.

    I think only certain species will damage the corals, but a huge infestation could cover everything in your tank. Agree with the guys above, just keep an eye on them.

    howzit merlin, hows things vying? long time?
    i got lots of these stars in my tank too, some people told me they cool, but most say they are a pest, so like you say, i just take out what i can when they on the glass and all seems fine. and i agree with that gorgeous star you got there, i wouldnt put any harlequins in. sharp bru.

    Just remove them physically. I have about 5 in my nano tank, the only things that they are eating is the coralline and the algae on the glass. I don't have sps coral so I can't advise on if they will nom those coral.

    Thanks for all replies guys.sake? That is the question. To be honest I do not see them climb onto any of my Corals thus far. Bare in mind that these are the blue ones. Are these specificully I will maybe opt with the manual removal off the glass as they go there each time. Definately not putting in a HS as I love my Orange Sea Star and hope to get another two more different colour stars soon.

    Cheers

    These stars are good cleanup-crew. They do indeed go and eat dead or decaying flesh from corals. They usually live off detritus and rotting plant/food/meat...... You can sump them - they will do a great job in the sump.
