Does anyone know what this is?

Found these in my sump. IMG_20170614_161037014_HDR.jpg
 
I don't think you can get rid of them purposefully, so it's a little moot. :P But yes, they do seem as beneficial as any other small snail – with the bonus that they seem to do a good job reproducing on their own!

Asterina stars and Limpets are probably 90% of my cleanup crew. :)

Well that's good to hear, any thoughts on that sponge looking thing?
 
I'm hoping someone can help identify what this is. I'm not new to fish tanks, but this is my first saltwater tank. My wife seen this yesterday so I took a picture of it. I just thought it was some sort of algea growing. When I got home today it was gone. It kind of looks like a starfish the more I looked at the picture. I just want to know is it something I need to get out of my tank when I see it next time. Thanks

hi I have a 55 gallon we have Aton of those they are harmless Intill they breed then you will have a lot of them after that if you get a clam or any coral be very cautious a way to get rid of them is to get an harlequin shrimp they will eat them also they don't get bigger than a dime.
 
You've got very "live" live rock; great biodiversity and fun to watch.
 
I agree that it's a sponge-looking thing....watch it grow and try to keep it alive! :)
Shouldn't be too hard there are 4 of them in my sump. I will take a couple of pictures of other sponges growing in the DT in a little while. Thanks for the input.

Yeah I do. Tanks been running for almost 3 months and there's always something new in there, its great.
 
Here are the other sponges things that are growing in the DT. Any clew what they are? IMG_20170618_093656.jpg
 
"pineapple sponge" is what I've seen them called.....try googling for confirmation
 
If those asterina starfish get out of hand (and they will eventually!!) pick up a Harlequin Shrimp. They are suppose to eat them.

They do, as of right now the most I've counted is 4. So unil there unsightly I will let them be.
 
Ok, got another one for ya. Just found this chilling out on my front glass. Can anyone ID please. IMG_20170717_194953919.jpg
 
Looks like a sabellid type of worm without the tube. Basically a feather duster.
 
I reposted this picture in the hitch hiker forum also. Better chance of it getting seen there. That's what the consensus was there too.
