Spiky armored sand slug... thing

[NewReefer]

So I saw again, this crazy looking worm-thing.

It is sand colored, tan with dark spots.

Its looks about 1cm long, and maybe .3cm thick.

It moves slowly, and I've seen it suctioned unto the tank wall.

Any ideas?

Sounds like a nudibranch to me. Check out Melev's Reef - Visual Identification and Indo Pacific Hitch Hikers

Many nudibranchs are predators and horrible to have in your tank, if you can't positively ID it as a good guy, I'd remove it.

....... but the first thing that comes to mind is a nudibranch

I checked out the pictures... and couldn't find it under nudibranch... or slugs... or worms...

It sort of looks like a sand colored rolly-polly bug without plates and with spikes or horns on its back. It is camping out inside an empty snailshell right now...

I'd take it out.

 

[daugherty]

i think i would take it out also to be on the safe side

Does it look like this?
Melevsreef.com - Amphipod

hmm, i might have something like that too, lemme check out my pics. though your thread title gave me a good chuckle =p

My creature is not the amphipod... though I do have those in my tank... what are they?

My creature has a slug/worm shape body, with skin similar to a starfish or something - rough and kind of spiky - and it hardly moves at all. and its still really small... I will take a picture of it if the opportunity arises...
