I think on the videos those are medusa worms and are a good cuc. The flat worms i suspect are normal planaria that everyone sooner or later get, a wrasse or damsel will help controle it, my favorite wrasse for those is leopard wrasse.

The flatworms are pretty harmless till thier numbers get bigger. The danger is the numbers getting to large and smothering coral.

Be careful if they die in large numbers they can release toxins killing everything in the tank.
