Hi all

A little help please, found this guy.

Do we think keep or get rid? I think its some form of asterias and read differing views on them?

All views and advice welcome.

I kept mine. I have 100 sometimes and 1,957,455 others.

Def an asterina. If you have one, you’ll have others. I don’t like them but honestly can’t say they’ve caused harm. And some are big ones

 

[Got2bSkUnKeD]

Yea. Asterina. Some people don’t mind them, others borrow a harlequin shrimp from someone to devour them.

So if there will be more I guess no point killing this one and let nature be?

 

[WVNed]

Unless that is the first one. They divide.
They end up all over like some snails which doesnt bother me.

Strangely there are none in my other tank that is connected to this one through the sump.

Personally I keep them but they can eat really small zoas, established zoas and palys never disappear but ive caught them eating small zoas that were stressed from shipping.

I've seen white spots on coraline algae when they sit on it, it could be eating coraline, im not sure but I spear them with an exacto knife its fun sometimes....
