What's this starfish?

And what do you suppose happened to the rest of it's arms?

Could it be an asterina starfish that came over half eaten on a frag or live rock? If they had a harlequin shrimp, it eats them.

 

[joeyprice]

yes, I'm pretty sure that's what it is. I guess they reproduce by dropping limbs, so its not uncommon to find them in an asymmetric state.
Must have survived my dip.

Yep, asterina star. Not a big deal but their population in any tank can fluctuate and I'm dealing with an over abundance of them in one of my systems. When I can get them, I just remove them from the system. Typically you'll see more when the lights are off or dim. In my case, they are all over the place in the morning and disappear when the lights start to come on.

I'd take these all day over the spirobid worms that I cannot get rid of.

I just read that bumblebee snails are effective against the polycheate worms. I continually scrapped my spirorbids off the glass and back wall. They eventually stopped exploding when the back glass developed a velvety algae coating. I don’t see them in the tank anymore. However, I swapped for those little feather duster things, again polycheate family!

I scrape them off the glass, but they're all over the rock as well. No signs of slowing. I will try the snails next, nothing to lose I suppose
