Odd looking creature. First ive seen in tank. What is it?

[NewbieReefer11]

Hi i was just looking in my tank and i found this wierd creature. I am scared this may be a zoanthid eating nudibranch or similar.
Any help is appresiated.

Hard to tell from the photos but looks a bit like it could be a stomatella snail. Plenty of pics on google so you can double check. If so you are good as they are harmless grazers.

I see a crab but it’s hard to tell, could be anything if you ask me. Can you get a better pic?

 

[samnaz]

Was it moving slowly like nudibranch or slug?

No not really here r more pics

It’s not a nudibranch or flatworm. Definitely looks like a crab to me, if you zoom in you can even see an eye. If you can remove it, put it in a little cup of tank water for a better picture. Much easier to ID that way

I tried to catch it but it ran under some rock.

Yeah it pretty much a crab but it has a long nose/snout

Could it be a decorator crab? It’s really hard for me to make out but they have a long “snout”

Yeah i think you may be right. I checked online and some look pretty similar. Should i be worried the only corals i have in the tank are, gsp, zenia and some zoas that came on the live rock. Also the anemone for the clowns.
Could this cause harm?

 

[TheEngineer]

They will collect some corals for their shell if it is indeed one. I think it is otherwise Reef safe.

 

[samnaz]

What on earth.... it has the exact same snout as a goldringed cowrie. I never knew crabs could have snouts. If it is a decorator they are funny little characters.

Decorator crab. Harmless

I can’t remember what they are called but there is a small thin fish that sometime live in a fishes butt. Could it b one of them?
