The crab shouldn't mess with the starfish but if you are having a serious algae "problem", you may want to think about Astria snails instead and/or some other algae eating fishes. Also, you want to keep a check on the nitrate levels in your tank. Algaes grow when they have a food source and nitrogen (in it's many forms) are a food source.
Hope this helps...
