Star shaped stuff?

What are these star shaped things growing on my rock? Noticed 5 days ago with one on glass, but now all over. They are about the size of a pin head.

You could just pick them out whenever you see them or invest in a Harleguin Shrimp.

Like Woody390 said, they usually just eat algae(coralline algae) but can(and are highly known to) turn on corals, specifically zoanthids

I would leave them. They may never touch a coral. It's like anything else in this hobby. I've seen "reef safe" tangs eat thousand dollar corals.

Definitely invest in a harlequin shrimp! They are one of the coolest additions to my tank so far.. He will eat alot of those pesky little seastars. If you get one here are some facts:
-completely reef safe.
-Mostly active at night.
-Passive to inverts and fish
-May be fed every 1-3 weeks by purchasing a chocolate chip starfish depending on how big and how fast it eats.
Just a side note- chocolate chip stars are not reef safe so make sure the harlequin is hungry before you put one in the tank. If you arent comforable putting it in your tank you can seek alternative food sources with some reaserch online

I have a harliquen shrimp but I wouldn't suggest getting one to get rid of your issue. Let them be. If it gets too outta control then I'm sure there are other avenues I'm sure. Spend money on the shrimp and then 10-20 bucks on a star to feed your shrimp maybe not worth it in the end.

Plus you have to keep an extra eye on water parameters as the decaying stars body can foul up your water a little.

Don't get me wrong, I love mine. But I bought mine because I wanted it and so did the wife. Just gets expensive after awhile.

Mine cost me a few bucks.
