The first is a Spaghetti Worm, a detrivore and thus good guy. Butterfly fish will eat it, as will some wrasses.

The second is a type of tube worm akin to a smaller feather duster. Filter feeder and good guy. Butterfly fish would eat it.

What you need is a critter id page. That's something we are still working on for this site, but for now, this will get you by:

I have only known the second one as a "fan worm".... do not know the scientific names for them, they arefilter feeders -
