Yes they are flatworms.

So you have a 6 line wrasse currently? Try not feeding the wrasse for a day or two and then taking a turkey baster and blowing the flatworms off surfaces and see if that entices the wrasse to eat them. Regular blue damsels will also eat them.

If all fails research Flatworm Exit. You will have to remove as many as possibly manually because flatworms release a toxin upon death. What you see is probably a small percentage of the total population.

Good luck

Melanurus or most of the Halchloeries wrasses will really gobble them up and are less of jerks than 6 lines IME. Leopard wrasses will eat them too. It is hard to tell from the pics, but they look like the harmless red planeria, so you can take your time to get rid of them - they are harmless, but are hard to control after a while. You can suck them out quite easily with water changes and let the wrasses get most of the rest - some will likely always be hiding to where the wrasses cannot get to them. If you really want them gone for good, then wait for the wrasses to do their jobs until you cannot see any more, get some carbon ready and then flatworm exit your tank.

I have seen a copperband eat them with my own eyes, they just don't eat enough of them to effect the critical mass. If you get a suitable wrasse, their stomach will look like it is ready to pop while they gobble them all up.
