Pix & ID: Critters that come in your rocks: the good and the bad.

[jlp.xiii]

Those are very unhappy palythoas. They may come around with good water quality and lighting.

Thanks for that ID, here's an updated pic, although the quality isn't the best since it's from my phone, lol. My SG had climbed a little to 1.028 so I did a water change with RO and I had just installed a new 36" set of LED's two days ago so I think they're gonna do okay! Any care advice for these guys?

How big is it? Baby bristleworm?

 

[SaltwaterTeabag]

Very small, a 1/2 inch or less.

looks like a baby bristle to me

That would be my guess as well, an epitoke. Harmless.

Thanks to all for the input and help.

So, I brought home a nice big live rock from the LFS the other day, I'm watching it in my qt for a couple days before it goes into my brute as seed for my new Marco rocks.

In the meantime, it's been fun to watch. Has some nice macro algae, lots of pods, some sort of small clam and more.

The weird one is some kind of worm. Lives in a hole or tube in the rock, and extends out to graze over the rock around the mouth of it's hole. It extends out at least an inch. It's dark brown, and smooth skinned like an earthworm (not ribbed). It actually looks much like the snout of a Nassarius snail. Very reactive to light, it goes back in the hole with a quickness!

What is it?

 

[Sugar Magnolia]

Sounds like a peanut worm. Harmless.

Any idea what these are (if anything)?

The rocks have only been in my tank for about 2 days now and I'm starting to be able to tell what is and isn't rock.

The pictures are zoomed in and kinda grainy. It's hard to see but they are red in color and clearly not part of the rock.

 

[Martini5788]

How zoomed in? Maybe a macro algae of some kind?

 

[tehpineapple]

It's zoomed in as far as my iPhone6 will zoom. The one in the middle picture is sticking out about 1/4". They are all about the size of a standard pencil eraser.

 

[Sugar Magnolia]

Foramineferons. Harmless.

 

[tehpineapple]

Cool, thank you

I found this spider web like material on my live rock. The tank has been established since January 2015. I have not ever noticed it move or get larger. It does not light up under the actinics. I also gave it a poke with my tweezers and it felt soft and fragile. The spot is approximately the size of a quarter. Any ideas what it could be?

Please help identify I have two hitchhikers in the same she'll I think one is a bristle worm, should I leave him? The other comes out of a hole in the side of the shell slowly opens like a flower than if startled closes and hides super fast. What are they and should I leave them?
