Got a hitchhiker or unknown critter?? Check here for an ID

[shollis2814]

These are nocturnal and will prefer to be left in his little cubbyhole.

Makes sense that I noticed him as the moonlights were coming on.

I noticed these on my newly purchased zoanthids in my QT tank. Is it safe?

 

[Lionfish Lair]

Yes, it's a munnid isopod.

 

[lnataniel]

Thanks. There were so many I got worried as I was about to introduce the coral to the display tank.

Can anyone Id this hitchhiker I found in my sump?

 

[Eckolancer]

Kinda looks like a gorilla crab if so they are bad

I agree, it looks like it has black tipped claws.

 

[pilot108]

It does have black tip claws. Will it be ok in my refugium?

We found this on a very stressed out leopard wrasse. The thing fell apart when i tried to get it out. All the feathery tenticly things fell off. The first picture is of the main body, the second is of the stuff that came off it. That stuff is moving on its own too!

What is it? Thanks in advance!

That's a nudibrach. Reminds me of a starving Phyllodesmium poindimiei.

I actually just googled that. I guess it was in there eating coral and not the fish. darn. Now I gotta get back to the search for a monster. Thanks for the info!

I know it's a limpet. But what y'all think about having them in your system?

Reef safe?

 

[Lionfish Lair]

I would love to have a scutus. It eats algae and grows BIG.

From the look of it, it's not finding its preferred food. He's literally starving. They tend to fall apart when they get to a certain point.

Ok. Thanks.

 

[shollis2814]

OK, I am having a resurgence of unknowns after my diatom/vermetids have died back.
If this were out of water, I would call it yellow slime mold. I am sorry for the fuzziness of the pictures. They don't look like tentacles, but I could have seen it in a shrunken phase. With and without flash.

 

[Lionfish Lair]

It's looks like a sponge.

 

[Catchemall]

Sorry for the bad blue pic. But I have a bunch of these little bugs on my rock. They're smaller than amphipods they're round don't look like Copepods what could they be and are they bad or good? Thanks

Anybody know what these are in the attachment. What are the little bugs you can see on top of the rock?

 

[Lionfish Lair]

I can't see anything in the picture. Sorry.

Those little specks that look like bumps on the rock? Look closely, do they appear to have shells? Or do they look like miniature shrimp?
