Yet another discovery today, I am at day 18 of going fallow due to ich and I am seeing all sorts of new things happen... Today's discovery... Can anyone help ID this one and if so is it harmful or helpful?

Looks like some type of planaria/flat worm.

Thank you for the ID. What is the best treatment method for the display tank? There are only softies and LPS in there now along with snails, shrimp, and some crabs. Right now the tank is fallow as mentioned so I want to get any issues worked out before the kids get back in the pool. Going forward all fish will be quarantined and treated as well as a separate quarantine for corals.

Best of luck to you, I can empathize with unwanted hitchhikers.
