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

Great pics and info. My partner said she saw a worm fly out of a candy cane frag we bought but hasn't it again, even when we stripped the sand out. Got some aptasia though. How quick do they take over a tank? Mines a 160ltr so quite small for a reef.

Is this a coral?

Is this a coral?

I've been using the site and Google to identify all the little creatures that have appeared, but this one has me stumped.

During the day, or any light for that matter it's just a green blob, but if I turn the light on after a hour of no light it opens up like the picture.

Any ideas?



Cheers

Is it a ball anemone?

The hairier the scarier?

Was just splitting my new starburst polyps and this little guy came running out. He's about 1.5cm long/wide.

Any ideas? I have some soft corals and zoanthids, so if he's not reef safe I'll dump him. He's in my quarantine tank for now.

Thanks!

And in the quarantine he should stay. There are almost no reef safe crabs.

 

[Sugar Magnolia]

Agreed.

I have found something looking like feather duster but not sure, any ideas is it harmless:

Yevgenb, your coral is beautiful. Can you tell me what it is? An Acan, maybe?

Awesome sticky! Does anything eat spaghetti worms?

Why would you want something to eat them? They are highly beneficial. Their population is regulated by the availability of food. If you have a high population, cut back on feeding.

Sounds good. Thanks very much!

Is this maybe a limpet?

[dudemp52]

Looking for a little help on what i found on the glass of my tank. The tank has been set up for a number of years. Do not know if it is a bad Nudibranch It is about a thrid of an inch long.

 

[italquam]

Are these vermatid snails???

 

[Kanejr10]

@dudemp looks like a nudibranch to me I cannot specify the type as there are so many but generally from what I have read and seen other say remove he's a bad guy. They all have a specific food source which could be corals. I'm new but thats what I think it is. Might want to wait for a more experienced reefers opinion.

 

[irnv7tra]

@dudemp yea, looks like nudibranch, but not sure what type

It's an aeolid nudibranch, coral eater.

 

[Dombake]

I thought this was an Asterina star but not too sure.. Anyone help? It moves fairly quickly when it wants. Is amount 10mm at widest part.
