Hydriod and some kind of flat worm?

[Vested]

Got a pretty good picture of these two near each other on the glass. Im fairly positive on the hydroid ID, but dont know much about the worm. Anyone have a better id?

Medusa stage hydroid (common in new tanks) and will disappear in time. Ghost flatworm, they eat pods and other small crustaceans.

The cool thing about the hydroids, they can actively swim and hunt for food.

Question, did you start off the tank with live sand? Arag-alive? I’ve always found them in new tanks with that substrate.

mostly aragonite special grade dry, then like 6 cups of the same stuff from an already established tank
