Pictichromis Diadema

Pictichromis diadema is the first dottyback to be kept in captivity. They are widely sold for the aquarium trade. A very skittish addition to any aquarium, one should be wary to keep this species with other fish of similar sizes; if the Pictichromis diadema is the bigger, he will attack them, whereas if he is the smaller, he will hide most of the time.
