Dwarf angels & feather dusters, red grape algae & dragons breath???

[duganderson]

I know all fish are different but is my Dwarf Angel (Flameback) likely to eat feather dusters, red grape macro algae and/or dragon's breath macro algae?

I also have a 6 line wrasse but I don't think they eat any of these things.

IMO, the feather duster is safe, but the algae could become a target.
