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

Three Hitchhikers I'd like help with please:

Is this a Kenya Tree? It's pretty small yet, ivory color with tan markings.

A couple of these black things...they don't move. Are they sponges? Are they bad? I have many different colored sponges in this tank.

These round and oval things are red but they look scalded or like coraline has grown over them. Is it red bubble algae or something else? Should I try to remove them from the rock? There are quite a few of them.

Thanks everyone.

A Kenya tree, a black sponge, and some sort of red macro algae would be my guesses as well.

Can someone tell me what these things on my rocks are? They open up and a feather looking arm comes out.

Can anyone tell me what kind of anemone this is? It came on one of my live rocks as a hitchhiker.

Barnacles, harmless.

Pest anemone. Either a majano or aiptasia. Inject it with some lemon juice or kalk slurry.

 

[Ellemarley]

Aiptasia.... right?

 

[Cbaby1177]

What is this guy? Moves like a snail and has snail like tentacles. Couldn't get a better pic cause he disappeared after I took the first pic.

 

[Cbaby1177]

I think it's a stomatella.

Yes.

Yes, stomatella.

Hi everyone.

Found those little guys in my tank recently. It's definitely a nudibranch, but i don't know which one...

Doesn't seems to attack any corals directly, as it's roaming around the tank. Even sponges are growing. No algaes either...

Any ideas?

The first picture just looks like the legs of a small brittle star fish. (harmless) I'm not really sure about those orange slugs. Perhaps these links will help.

I was wondering if someone could tell me what these orange things on my rock is? It just showed up today. My tank has been cycling for about 2 weeks now

 

[mx51]

Thank you

Thank you

Palythoa, button polyps.

These have appeared on a rock that previously had several mushrooms on it. The mushrooms receded and now these guys (biggest about 1/4"). They seem to have 8 rays or legs.

Also saw this worm today. Sorry for the picture he was very small and wouldn't hold still. Could it be a small eucinid?

 

[Sugar Magnolia]

The corals are clove polyps. Hard to tell with the worm. It may be a small nereid. Have a look here - http://chucksaddiction.com/hitchworms.html

 

[hogfanreefer]

Thanks SM! That's weird. I've had that rock for probably 8 months and haven't seen those till the last few days. Glad I got it out of my DT. Really don't want clove polyps.

The worm must be a Dorvilleidae. The pic and description looks just like him!
