Most will likely tell you that they are a friend- this is accepted as "common knowledge." However, it depends on how you want to keep your system as to weather they are friend or foe. I try to keep mine fairly natural and prefer all of the life that I can get- so they are foe. Yes, they eat some stuff we consider undesirable- but they will eat anything they can pick at including lots of small but beneficial life forms. They do not occur in anywhere near the numbers on a reef that we are told to add them in our systems (if memory serves they average a maximum of 1 per square meter.) It all depends on what you want from your system and how you want to keep it.
