Opinion about Asterina starfish ?

[Sman]

I found a couple of these in my tank after I added a piece of live rock from a friend , I took them out . Just curious if I should worry about them .

If they are in there they will multiply. As to the question if they will hurt anything im not really sure. Had them in my old 90 gallon tank and they were all over the place! I got a pair of harlequin shrimp to take care of some of them.

I have heard they will eat coral. I have several and have never seen them on any coral. I take them out everytime i find one.

Take them out. We let them be and they just kept multiplying. Then started eating zoas yes they can be a good cleaner but they can also cause issues to coral so I remove them.

They suck. They will eventually multiply out of control. I can't get a harlequin shrimp because of my melanarus and mystery wrasse.

I have always had a small amount in my tank, mine don't get out of control or bother coral bit several other people get issues from them. What I do have millions of is mini serpent starfish, there must be ten million in my tank.

They eat coralline algae (the purple pink algae on your live rock) I have also heard that the ones with the red on there back have been known to eat Zoas..

Thats the same ones ive had in my tank for over 2 years now. Never had a problem with them bothering corals and mine havent multiplied out of control. The Red Asrerina Stars are the ones to worry about. So removal/keep is up to you.

ive witnessed them eating my zoas, since adding some peppermint shrimp they are nowhere to be found.

I also have the same ones u pictured and have never been a problem other than crawling on stuff and polyps closing. Def Dont eat coral!

Removal is a losing battle unfortunately. Harlequin shrimp, will eliminate them.

Oddly enough, since I removed the dwarf angels from my 75 (( tired of my corals being nipped at all the time )), I have noticed them. Nothing has been added to the tank that would have brought them in, so I have a feeling that the dwarfs were keeping them in check.
