ID these

Can someone tell me what these are? I know the one is a starfish but what kind?

 

[AcroNem]

They're little sea stars that will show up in most systems, in the Genus Aquilonastra, formerly called Asterina. There's over a hundred species and all but a few are reef safe. Odds are yours won't bother anything in your system.

Not Asterina anymore (; I didn't see anything else in those pictures that looked like a sea star so I assumed that's what he was referring to.

What is the yellow item in the first picture? He pops in and out as well as the feather tube looking thing in the second picture. Sorry i didnt explain more

You are completely right on that but as long I live I call it astrina.

That is some sort of wild nem, not the majano or aptasia kind.
First of I thought it was a sponge but than I saw the little tentacles

Looks a bit like an anemone, or even a Tubastraea sp. Does it have a skeleton that you can see?

Just like the rest of people in the hobby that won't use the new species names.

Seeing the new picture, I'm almost positive that's Tubastraea faulkneri.

Yep, it been 40 years for me as a Astrina it will be another 40 years for me.

The yellow thing does not seem to have a skeleton it looks "soft" the item with the feather looking object seems to have a hard tube

These are really cool looking!!

 

[AcroNem]

I can see what appears to be a tube, or the corallite under the flesh. Speaking of flesh, the polyp structure matches Tubastraea, I can't think of anything else it can be. The other things are feather dusters, a kind of tube worm.

 

[Keeks09]

Are they safe?

 

[AcroNem]

Are they safe?

Yep. Granted it's not photosynthetic so you'll need to spot feed it for it to survive as it grows. They're not "hard" to keep, just need diligent feeding every other day, or every day if you can.
