Is this a 'flat worm'?...

At night and eraly morning, I have these s

small, flat things on my glass.
Not everywhere, just a few.
Most are smaller than a mm in length.

This pic of the big one is actually less than 2mm in length.
It has only the blue lights on also right now.



Here are a few smaller ones.



I never see them on any corals, and they don;t seem to bother anything, and I don't see my fish eating them either.

Know what these are?

 

I don't trust any worm. I say nuke them!

 

they don't look like flatworms to me but I am far from an expert. They're actually pretty cool looking.

 

It might be a baby chitin...

 

Or similar. It looks like perhaps young limpets too.

 

Cheryl, and those certainly are OK right? They've never posed a problem.

 

Yeah, I have never had issue. If they turn into a larger variety than you might think of removing them if you see them hanging around corals.

 

Thanks for your infinite wisdom regarding these things.

I'll just keep doing what I'm do'in then.

That was the largest I've even seen so far.
