Newbie needing id. Spiny Bug?

[poochieparker]

Hello, Help, this is my first posting.
Put my first polyp zoa in yesterday and have about 4 kg live rock. Last night on the glass at water line seen for the first time looks like a spiky caterpiller, although does not move like one, it has 2 antennae like a woodlice, a bit like a bug, its about 1 cm in length, moved a bit like a snail would on glass,will try for photo, if it appears again, but can you help?

Thank You

Sure! It sound like you have some sort of hitchhiker. Grab a picture, and post it here- dedicated to stuff like this.

:welcome:

I have now seen three of these things coming out of my polyp, I have called my LFS where I purchased the said Polyp from and they say its a sea slug and I should remove them. He said the brown ones were not to bad its the white ones you worry about. Still trying for photo but I don't have evry good camera but still trying. Any Thoughts?

i think it is a stomatella snail

i have some that have somewhat "spikey" looking shells.

these are good critters. they won't hurt anything.

btgw..what do you mean coming out of your polyp? you mean they actually crawl out of the mouth of a coral polyp?

 

[poochieparker]

They look like this a bit?

Good or Bad?

that's not a stomatella varia. that might be a zooanthid eating nudibranch. i don't know for sure. :?

Hi

Thank You for your posts.

I have read through this article, and it looks like I have purchased myself some zoanthid eating nudibranch.

OK, from what I have read these are bad, how do I get rid quickly (only been in a day), will they come back once I remove the ones I can see?

 

[mr_X]

just grab them as you see them. as long as they didn't lay eggs anywhere you should be ok.
it's a good practice to dip your corals before you put them in your tank..at the very least, a freshwater dip will remove some critters.

Thank You again, for all your advice, I have got 2 so far, am having to knock them off my zoa then catch them in a net as they float about, I'm a bit squeamish about catching them in anything that might squash them, just hopefully 1 more to go

It's a shame my Clown or my Blennie are not interested.

Do hermits not kill these?
