I see this small pinkish slimy things that move on the stalk of my leather corals, what are these ? Are they harmful ?

My guess would be flatworms.  Some are more harmful than others.  I’d do a quick FW dip and see how many fall off.  I had an Elegance that was covered in them........ did a quick freshwater dunk and they all died and I never saw them again.  

 

I have little tiny ones that also live on the glass.  They never bother anything and the fish like to eat them.

Thanks WV reefer. I can dip one of the leathers as it’s on a separate rock. But the other is attached to a big rock. Not sure if I can that out tho . 

I'd dip the one and determine what flatworm species it is.

 

Some species are bad and a complete tank treatment is required.

Definitely flatworm.  

 

Some do not eat the coral but they block the coral from receiving light.  Dip the easy one first to see how many come off.  Try checking the other Corals and see if you see them anywhere else.

@Joaly is your tank big enough for a small wrasse?  They are great at picking off small worms.  Not a small species, but I bought a small melenarus for a tank I had a huge flat worm problem with and everything was clean in a couple weeks.  It's an option of you cant dip.

It’s a 10 gallon nano , most of the corals are attached to live rock .
