he goes for my snails not my hermits or my cleaner shrimp what can i get that is largish to sift the sand bed, was thinking about goby but im quite stocked will he add much to the bioload?
After scott suggested a goby to me I started reading about them.
You could try Valencienna puellaris or Valencienna strigata. Two of the most common. Plus they don't get to huge and should readily take aquarium food, which is good to sustain them long term.
