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

[skene]

Definitely not polyclad as it balls up like a seahare... just want to know if it's a good kind or not.

I posted this question elsewhere but I just found this sticky. I apologize for the cross-post. Can anyone tell me what this is? I found it peeking out from a new piece of live rock while I wait for my tank to cycle. Is it anemone? coral polyp? something totally different?

Thanks for any input - I'm brand new and learning as fast as possible.

 

[AmberFL03]

Definitely bubble algae?

 

[AmberFL03]

What's the red tube thing?

 

[AmberFL03]

Is this halimeda? Is it dead? If so, Will it come back to life as my new tank cycles?

 

[AmberFL03]

These branchy things? And are they dead?

 

[AmberFL03]

The fuzzy stuff? Good/bad?

What kind of anemone is this?


It kind of resembles aptasia but not really. It doesn't look like a good kind to have in my tank though. I have found 2 of them.

 

[Sugar Magnolia]

It's aiptasia.

I'm still hoping for a response on what this guy could be... anyone? It's currently about the size of a pencil eraser.

It's a pest majano anemone. You'll want to kill it off before it starts multiplying.

Thanks! How do I kill it? I tried to reach in and grab it but it pulled back into a little hole in the LR.

I hear a syringe of scalding water helps... But I've never tried it

Vermetid snail. Its a stationary snail that deploys thin string like webs to capture food. Generally harmless but the web can irritate neighboring corals causing the corals polyps to remain retracted.

Need helping IDing something on my mushroom rock. Just noticed it had a string coming out of it!

If the creature in question in the fourth picture is hard/calcareous, my guess would be homotrema rubrum. Harmless.

Was wondering if I can get some help on a couple of hitchhikers and some sponge"?" on my new rock.

A brown legged hermit.. is he safe?

Is the snail a whelk or what?

Two different types of red sponge?

This is my second go round with this Biocube 14g. The first time I had a mantis sneak past me and just devastate my livestock. Tank ended up as a crab house with lots of dragon's breath algae that I sold to the LFS. From what I read this go round I am planning on limiting any crabs other than blue legs to the sump and possibly those too after the tank gets settled. Let them clean up for now though.

PS... It's not slimey. Are there any green coralline algae?

Late last year I set up a brackish water Opae Ula (Hawaiian Red Shrimp) tank. In it I put several pieces of live rock with very interesting results. In amongst the critters and algae that survived the transition from marine to brackish conditions is this green something that has grown a lot over the months.

Any idea what it is? At close up it has a very interesting texture not captured in this photo.

Please help ID this if possable.

Sorry for the quality of the pic, this thing was less than 1/8 inch. It was on the glass, looked like it had some kind of hook on the head. Is it some kind of flatworm or what??

 

[cloak]

Some sort of nudibranch? I'd remove it. Better safe than sorry.
