Good or bad?

[loweryphil]

Dont know where this has come from. My tank has been up for 6 weeks and all of a sudden this appears?

asterina starfish. There are good species that are great for CUC but other species that will eat coral. Id manually remove.

Asternia starfish. Can be invasive and known to munch on softies, but many will ague about it. I get rid of any I see.

Asterina starfish Link

You have the white ones, as I do and in my system they only multiply, but have not cause an issue in the past 8 months since I discovered the stars. A harlequin shrimp will take care of them but when the stars are gone, one has to either re-home the shrimp or feed the shrimp bits a pieces of live star fish or the shrimp will starve. I have an eight line wrasse and he likes shrimp, so that method of control is out. I have also read that a certain typed of star fish is also eat it's own but I am not quite sure if the star is reef safe.

Hmmm mixed response. It seems unknown

 

[stevo01]

More like make your own choice.

I have the white variety of asterina starfish in my tank. They don't harm my corals but do multiply like crazy. I just manually remove them from time to time and put them in my sump

What corals do you have? This seems to be the white type too

 

[loweryphil]

Read these guys eat corralline too?

 

[Garrett W.]

i have dozens in my system and they don't both any coral or seem to eat coraline. If they do the result is negligible.

So why remove? Personal preference?

I remove because they can in time overtake your system. The dark ones will eat corals. I just do not like anything that reproduces that effectively, and I like my coralline.

I love asterinas: they make my starfish great snacks.

I have duncans, hammers,bubble, frogspawn,candy canes,blastos,frogspawn and toadstool leathers

 

[loweryphil]

Cool. And no visible effect? Ive only seen one. So i could rid my tank of it but am holding out as i think theyre cool.

None at all. They just hang out on the glass

Yeah it's just personal preference. I don't like dozens of tiny starfish obstructing my view haha.
