Thanks again for the information, I thought that it was some type of brain coral also but I'm definitely no expert on corals. So Do these rock dwelling cucumbers look just like the sand dwelling variety only they are wedged into a rock/crevice? I'm assuming at the size they are now that they do not pose any threat to my tank as far as poisoning the system should they flip out for one reason or another? About five months ago I purchased just 10 pounds of some Florida live rock just to see what it looked like before I bought more for another tank. It definitely had tons of life as far as inverts, sponges, algae and other types of brain coral but I am surprised that now I am starting to see lots and lots of different things. I've found about six small tunicates and sea squirts, bristle worms and stars As well as some unusual types of porcelain crabs. I had the crabs identified by sending pictures To a professor of marine biology in Florida. I can't remember the exact name but they only get about a half inch wide and are members of the porcelain family and are supposedly reef kinda safe. Anyway, it was the best $70 I ever spent for such diversity. Thanks again for your help, David

I wouldn't worry about any poisoning to the system. They have the same body type as all of the other Holothuroids, they just have a specialized mouth for filter feeding.

Great informative post. Nice to know that the amphipods and copepods are good guys. Just started seeing a lot after about two weeks cycling and at first freaked me out.

skene · 07/17/2013, 01:45 PM

Can anyone tell me what type of Nudibranch/Sea Hare this can be...? Want to know if it's good or not.

SushiGirl · 07/17/2013, 05:01 PM

Looks like a flatworm. If it's a polyclad flatworm you don't want it in your tank, they at snails or clams.

skene · 07/17/2013, 10:37 PM

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

ChiveCK · 07/18/2013, 08:08 PM

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 · 07/18/2013, 11:41 PM

Definitely bubble algae?

AmberFL03 · 07/18/2013, 11:42 PM

What's the red tube thing?

AmberFL03 · 07/18/2013, 11:44 PM

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

AmberFL03 · 07/18/2013, 11:50 PM

These branchy things? And are they dead?

AmberFL03 · 07/18/2013, 11:53 PM

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 · 07/20/2013, 02:26 PM

It's aiptasia.

ChiveCK · 07/20/2013, 03:16 PM

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

Sugar Magnolia · 07/20/2013, 08:10 PM

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

quagmire · 07/21/2013, 12:54 PM

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.

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

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.

Rob in Puyallup · 07/21/2013, 01:13 PM

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

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

Dave.H · 07/21/2013, 02:36 PM

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 · 07/21/2013, 05:36 PM

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

jtp79 · 07/22/2013, 02:02 PM

The guy I got the tank from said a large bristle worm. Doesnt look exactly like the pics I have found of one. This thing is big,,,I have already put it back in my tank and it has disapeared,,,,good thing or bad?
