If they are you need to be very careful of how you remove them. The red ones are usually toxic so if you use something like flatworm exit at the density you have you will kill your tank more then likely. I say take a air hose with a small piece of rigid tube with one end cut to an angle and manually suck them up. Go in at night and cut all lights out except a clamp on light at one side. Then wait a few hrs for them to move to the light. Then remove them.
Or another option is take out all the rocks and do a freshwater dip or at least a saltwater dip of way lower or higher then your salinity is at now. The change of salinity will cause osmotic shock and they will fall off and pop. This is the fastest way of getting rid of these safely. Flip side you have to take your tank apart. But that is the option i would do if my tank had that density. Just make sure you dip the corals as well so nothing comes back in. You don't normally need to worry about eggs as they normally split through fusion to multiply. If you can find one look for a nudibranch, Chelidonura varians. They only eat flatworms.

holy. buy a wrasse and start sucking em out
Judging by the pictures that is a very heavy infestation and one fish will not keep up with it. I have not seen one that bad in years. Going forward a wrasse dropped in after it is taken care of will help slow or possibly stop it for happening again. The wrasse will more then likely get full long before he puts a dent in the numbers. It can't hurt to try but drastic measures will need to be taken to curb that density in my experience. My brothers tank had to be taken down and everything dipped as the wrasse did not work. His was way less then those numbers in the pic.
I had a similar issue a few tanks ago. I siphoned as much as I could out daily for about a week. Once the population was almost visibly gone, then I hit the tank with Flatworm Exit. I also made water like crazy to do some large water changes afterwards. Only took one dose

Totally treatable, do as Torx says- siphon as much as you can over a few weeks, them hit it with Flatworm Exit. It might take a few treatments but it will get control over that population. Ensure you have lots of pre-mixed water ready to go for for water changes as well as carbon. Plan ahead and you should be fine.
Infestations like yours can be related to lack of flow and poor water quality, so ensure you improve both of these parameters moving forward. Good luck!
