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

Found this on my live rock that is curing. Looks partly dead from shipment but want to make sure its dead if it's bad.

can anyone ID this hermit crab please?

can anyone ID this hermit crab please?

This guy came in my live rock. I'm thinking it's not a zebra hermit but that's the nearest I've seen.

Mainly just wondering if he's reef safe or if he's likely to kill my other crabs.

anyone know what this little guy is, he is in my refugium now. I posted this in the general discussion and someone suggested a juvenile porcelain. But I'm thinking it might be some sort of juvenile xanthid. Right now all that is in my DT is 3 tiny blue legs, an emerald, snails, and a peppermint shrimp. Along with way to much algae (hence the crabs)

But being so small I didn't want to loose him in there and not be able to grab it if its not safe for coral down the road. It came on a piece of LR I got today.

Size: >1cm across including legs

Found this living in a coral that I just brought home two days ago. Good or bad?
Sphaeromatid isopod, harmless.

It looks like a porcelain crab to me.
 
I don't think a porcelain crab has hairy claws...do they? :/ I forget, I don't distribute wild collected anymore...

Your flatwom looks like an variety that isn't harmful to coral...however, enough of them probably will be. Looks like the kind that sits on mushrooms and such...if you get enough of them, they can drown out the light for the corals, just blocking it. A wrasse will take care of them. :)
 
Just saw a couple of these in my refugium and have no clue what they are. What your looking at is the skinny worm looking thing that has a bunch of small clear whisker things coming off the one end. Sorry for the crappy picture but there are two in the photo.

Kind of answering my own. But could these be spaghetti worms? They match the description minus the fact that these two are not in the rocks or sand.
 
2 more ID's please!

2 more ID's please!

I have 2 of these that I have seen....this is the smaller of the 2. The larger one had some small dots on it.

And then I found this....the tentacles are not always out.

Thanks!
 
The last one is hidden cup coral. Good hitch hiker! The crab pictures are hard to make out but looks like predatory species to me. To the sump if it were me.

What's this? It's definitely some kind of mollusk, but what? It moves VERY slowly, maybe 1mm per day. Don't know what it eats, but it is growing. The apex of the shell is at the back close to the red spot, not in the middle like a limpet. It must have been quite small when I got it, as I used dry base rock instead of live rock, so it had to have come on one of my snails or on one of my small coral frags.

Even though the shell is very flat there isn't much animal inside (look at the reflection off the glass. Could it be some type of slipper shell?

Can't see the shell things very well but can see what looks like aiptaisia! (if you didn't know already)
 
Im sure they can kill corals and fish cant they , educate me if im wrong.



what about snails & limpits seems to be im getting infested with them.
 
What are you calling snails and limpets? Can you give us a picture?

Aptasia is a pest anemone in many circles. It can cause issues because of the speed it reproduces across a tank. A super majority of us remove them.
 
Ok thanks worm5406, what's the best way to get rid of these?


the white things are hard to see but there are like little round shells, maybe tube worms in the making?

it is not letting me upload any pictures?


i hate computers.....

the snail like things are round with a pointy tip very camouflaged in with my rock..
