They do have some chemically active defensive cells in the skin but nothing like the toxic sea apples (Pseudocolochirus species) which really can nuke a tank. Euapta species are sold as reef-safe. Lots of people have them which I doubt would be the case if they had a reputation for toxicity. I suppose like with every species there's individual variation so some might be more a bit toxic than the rest. You might want to do a RC search and see if anyone has reported problems with their medusa worms.
Some have reported tank wipe outs, while others have had good experiences. Considering all the work and $ I've put into my reef I think I'll err on the side of caution. Maybe I'll start another tank for a Medusa! I can hear the wife now... "Eeeeewww, what's that?"
