Anyone know what this might be?

Pulled this out off some liverock.

Maybe a baby Bristleworm?? @Lionfish Lair might have a better idea.

 

[Lionfish Lair]

It looks like perhaps it's a nudibranch. It it flat-ish?

 

[Hockeypunk1]

It's completely flat. I wish I could get a better pic. It's def not a bristol worm I thought it was at first then I looked at it under a microscope. It's about 1cm and it's head is shaped like an arrow with reddish spots all around us outer body

Polyclad Flatworm?

 

[Rookie2reef]

Yeah i would say flatworm

Another pic that shows a little more detail

 

[Hockeypunk1]

@Lionfish Lair I just posted a pic with a little better detail. Would you mind taking another look?

 

[Lionfish Lair]

Can you see two little antennae or is it perfectly flat?

 

[Hockeypunk1]

I didn't see any antenna. I would say perfectly flat

 

[Lionfish Lair]

Ah, from over here it looks like the dark dots are antennae. If it's flat, I'll roll with flatworm.

Don't put it back in.

Ok maybe antenna or eyes. Here is a pic under a microscope

Not knowing a lot but just tossing this around could it be a chiton? @Lionfish Lair

 

[Lionfish Lair]

No, it's not a chiton.

 

[Lionfish Lair]

Not saying this is the species, as we're just trying to figure out what it is, but have a gander here. It's a flatty, IMO after seeing the newer picture.

Yeah definitely just add some flatworm exit clear it right out for you, its reef safe too

Right on. I'm definitely going to monitor the situation. Hopefully this is the only one. I know that's unlikely, but I haven't seen any more. It is quite large so I'm keeping my fingers crossed. I have had the tiny white ones that eat algae. I was really concerned that it could be aefw or monti eating nudis.
