I have heard that Springeri Damsels will eat pests in our aquariums. I have a pair of Azure Damsels in my tank that are of the same genus as Springeri - Chrysiptera. I was wondering if Azure Damsels will also eat flatworms, nudi's, etc, or if this is unique to Springeri? My Azure's pick at the rock and substrate throughout the day, but it is hard to tell what exactly they are picking at.
