asterina star harmful for SPS

[ryanjiang]

Lately I have tons of asterina stars in my tank, in few occasions I saw one or two asterina climbing into the branch of acros. Is this a problem for SPS?

I had some tissue loss (not major) from few Acros & overall less PE , I think it is due to a recent ALK issue ( from 8-9 to 6.5) caused by jamming of dosing tube. Could it also related to the asterina invading ?

The stars are harmless.

So it is very likely they eat SPS?

I've already throwed in a harlequin shrimp, it settled down & getting fatter every day, but I did not notice the reduction of asterina. Maybe I should throw in another one or two, or do some manual remove to help?

The stars are harmless.

That was I thought, harmless to SPS. But they do seems to cause issue to my zoas.

But from google search, it does show someone saying they chow SPS if population is too dense.

very much untrue

there are countless different kinds of asterinas and some are in fact coral predators

You cannot tell by looking them, but you can tell by where you find them hanging out and if you see any apparent damage on your polyps or sps

Most are harmless grazers you find on the glass or rocks, but I have found both polyp and sps munchers and for that reason I do not discriminate

asterinas get tossed when I see them
