They seem to just eat algea, especially hair algea which I used to have a problem with till I quit using tap water. They would eat off the base of the algea, kind of like a weedwhacker, and leave the rock clean. I just to joke about them being "weedwhacker starfish"
Should I be pulling them out?
I think you should be able to leave the micro stars in your tank unless you witness them eating the corals. Among the micro stars, only one type has been shown to eat corals (Asterinas) and even then it is fairly rare.
Does your starfish look like this?
If it does, then it is an Amphiuridae mini brittlestar and they are reef safe (do not eat corals) and are very beneficial sandbed and rock cleaners (as you have witnessed). Now you just need trademark the name, say they are rare and make millions on eBay :)
