I'm a newbie at SW and i just got a fan worm. It's been about a week and it seems to be doing fine, but I don't know how to feed it or what to do to keep it alive. I have a well cycled 20 gal SW tank with 2 small perculas, one fiji blue devil, 1 sand crab, and 3 sand bugs.
Also, are you supposed to bury part of it in the substrate? How does it stand up?
