Very difficult to tell what they are from the photos. You might try identifying them on Melev's website:

Is there some reason you feel you need to get rid of them? Most of the random little things that appear in new tanks are harmless, and a lot of them just go away on their own.

thank you for the reference, from what i saw on melevsreef it they look most similar to the flatworm Red Planaria, but as you can tell the coloration is different. these actually aren't in my tank, they are in a friends tank and have become quite the nuisance, multiplying like crazy and apparently eating corals. i got these pictures from specimens we collected today and i scanned on the glass of my scanner, i will go over there with my camera and have some pics posted tomorrow.
thank you n8ster

thanks for the link, it didn't work but it got me in the right direction and i figured out that they are Convolutriloba retrogemma.
i still have found no way to get rid of them or anything that eats them. does anyone have any suggestions? it seams like everything this size just lives to get eaten by something bigger.

Flatworms (Red Planaria): How to eliminate them from your reef â€"œ by Marc Levenson
Small reddish-rust colored creatures may already be in your tank. Or you may buy a coral and they'll appear as hitchhikers later. They may appear on the glass/acrylic, on the substrate, or on live rock. Due to their extremely thin bodies, they are called flatworms correctly. They appear almost two-dimensional, barely a flap of skin or perhaps a 'dangling chad'. They can move through the tank, elongating the front part of their body like a sail filling with wind, latch on to the nearby surface and pull the rest of it's body forward.
They feed on small foods like rotifers, phytoplankton and such, and will grow out of control unchecked. Creating a mat with their bodies, they can smother corals or parts of the substrate. If they get to the point of overpopulating the tank, there is the possibility that they may die suddenly all at once, and the toxin they release at death can cause further deaths and even wipe out a tank entirely. Some predators exist, but results vary. Six Line Wrasses, Leopard Wrasses, Target Mandarins and even Blue Damsels reportedly eat these flatworms, as does one Nudibranch (Chelidonura varians), but some have opted for a different approach when these methods prove ineffective.
Salifert came out with a product over a year ago called Flatworm eXit, a poison that only affects flatworms and is reef-safe. Let me add the qualifier that if your tank is heavily infested, Flatworm eXit will not be the cause if you lose livestock. The issue is that if many flatworms die at once, their toxins reach lethal levels quickly and this, not the product, can lead to deaths in your tank. Feel free to ask others about their results before using this product. When I used it, the only item in my tank that appeared distressed was my Hawaiian Featherduster. Its feathers were shriveled up and wilted and it looked very badly during the treatment, but afterwards it opened up completely. SPS, LPS, soft corals and fish were completely unaffected, as were snails, starfish, crabs and pods. My infestation was low because I regularly siphoned out all I could see each week, before I ever dosed my tank.
What I recommend is that you remove as a many as you can before you treat the tank. This is what I used, the Flatworm Vacuumâ"žÂ¢ :
I put the bag in my sump, and sucked out all the flatworms I could reach and see. Starting the siphon was easy by putting the end of the rigid tubing in the flow of a powerhead. I siphoned out as many as I could find every day until virtually none were in sight. The less you have, the less toxins will be released when you treat. If you don't use a sump, you can put the bag in a bucket in front of the tank, and after the procedure, you might decide to pour the water back in your tank. If the water looks cloudy or reddish, it would be better to dispose of it and replace lost tank water with new saltwater.
The day I was ready to treat my tank with Flatworm eXit, I made up 20g of new saltwater for a water change. I also hooked up a canister filter filled with GAC (granulaed activated carbon), and tested it to make sure it was ready to run.
I dosed the tank with approx 60 drops of the chemical (1 drop per gallon), and the flatworms started to come out into the open, and died. They would die on a string, and similar to webbing, multiples would die on that thread. I used my vacuum system to suck out all that I could see. After the first hour, I added 30 more drops and continued to observe the tank and siphon any dead or dying flatworms. My skimmer was always on, but the bubbles were depressed due the treatment, and it took a couple of hours before it began skimming again.
After 1 hour 20 minutes, I turned on the canister filter filled with carbon to pull out impurities and toxins.
The skimmer did work later, and pulled out some stuff, but nothing like some of the horror stories detailed on ReefCentral.com. I did a 20g water change (55g reef plus sump), and they were gone.
It is recommended to repeat the procedure one week later, but forgot and never did treat the tank again.
About a month later I saw a few in my tank, but I've not seen one in a long time now. I do have two Mandarins, a Six Line Wrasse, and a Blue Damsel to work on any possible flatworms if they do reappear.
Some people take precautions when adding new livestock to their tank, always doing a Flatworm eXit dip for 15 minutes prior to adding the coral to their display to prevent spreading these creatures.
A suggestion by Salifert: If you've been unable to kill them with the recommended dosage after two attempts, try this experiment. Take one gallon of tank water, and add a few flatworms to it. Add one drop of F.E., and stir. Wait and watch to see if it affects the flatworms. If not, add another drop, stir, wait and watch. If necessary, add another drop and stir. Wait 15 minutes each time, until you see the flatworms are obviously distressed. At that point, you'll know exactly how many drops per gallon it will take to kill the flatworms in your system. Keep in mind, higher doses of this product in your reef may cause issues with your livestock. The purpose of this experiment is only to find out just how resistant they are.

I agree.. Red Planaria.
Flatworm exit made by Salifert works well and doesnt effect other life in the tank.
Siphon out as many as you can see before using the meds.. they are pretty toxic when they die in the tank.
It might take a couple applications a week or so apart, but if you follow the instructions, you should be in good shape.
Its a good idea to get rid of them asap, because they multiply very very quickly.
It is said that the psycho mandarin and the six-line wrasse are known to eat them. Dont count on this though.. its hit or miss.
Good luck!

I've heard that there's a species of wrasse that will eat them as well, but have nothing other than a failing memory to back that up.
