Hitchhiker ID please?

[edsreef]

Sorry if this has come up recently but I've been out of reefkeeping for a while and don't recall coming across one of these. About 1/8" diam. White/off-white. Moving slowly across my back glass. Came either off piece of live rock or in a scoop of seeding sand I recieved.

Juvenile Asterina starfish, most likely.

Agree with Joe, asterina starfish.

 

[re-fin-away]

Yup that is what it looks like to me.

 

[edsreef]

Thanks. Now he's long gone. If I see it again I'll remove it.

 

[kkrawler]

They usually eat algae and are harmless. Theres many different kinds.

Some will eat zoanthids.. If your lucky and they are the ones that don't eat zoanthids, they will still breed horrifically and crawl over your colonies and close them up everytime they do that.
