Plz ID

I was looking at the glass in my tank and saw these small organisms on the glass of the tank, They look the an elongated spade of a shovel head and are about twice the size of a copepod, they are white and move in what seems to be a snail like fashion i.e no limbs, sorry no pic

 

limpet?

 

Flat worm. Do they have an orange dot in the center of their body?

 

yup sounds like flatworms.

 

yep flatworm thanks guys, a 6 line wrasse will eat those right?

 

Not sure, but they're supposd to be pretty good with stuff like that.
