asternia stars

I look at them as part I my clean up crew. Never seen them do anything bad. Why do you want to get rid of em?
 
I took 50 and flushed them.
Then toom another 50-60 and gave them to a fellow reefer that wanted them.
Then I took 50 more and flushed them.

Now the population is a little under control.

I only got rid of them because they were eating all the coraline on my glass and making it look like crap.

I used to have a ton of them in my 72 gallon, so I bought a harlequin shrimp and she kept them under control.
 
I used to have hundreds in my tank but for some odd reason they all just disappeared.
Still have a few here and there.They never really bothered me .
But,I have seen some that will get on zoa polyps and either bother them or eat them.
 
If they are over populated it could mean you are over feeding. Cutting down on food may be the easiest method of control
 
The problem is,I believe asternia eat coralline.
So if you have lots of corraline,you will have lots of these stars.
