Notes: Pseudochromis/Dottybacks are enjoyable members of any aquarium. They are very active swimmers and will guard their small territory from all intruders no matter what their size. Pseudochromis also provide aquarium owners the benefit of feeding on bristle worms. Multiple pseudochromis can be housed together provided you have a large aquarium and there are sufficient hiding places.
