I just put my clean up crew in my 120 gallon tank. It is a new tank that just went through its cycle. It will be a mixed reef eventually. I know the obvious, they are a "clean up crew". Point is, I have no other livestock in the tank yet, and I have a bit of algae starting to form on the rocks. They are feeding on it, but I'm wondering if that's enough for the clean up crew at this stage???
