The Royal Dottyback,, Pseudochromis paccagnellae, features a half yellow and half purple body making for an interesting addition of color to most tanks. The hermaphroditic Royal Dottyback is hardy and low maintenance. The Royal Dottyback will certainly defend its claimed territory against similar looking fishes so caution should be heeded when housing with other dottybacks or basslets. If multiple of the same species are desired, they must be introduced at the same time. The Royal Dottyback may pick on small sessile inverts like tubeworms. It thrives best in a tank with plenty of live rock hiding places and a tightly sealed lid to prevent escapes. Their carnivorous diet consists of mainly brine and mysis shrimp. Any beginner or expert aquarist will recognize the Royal Dottyback as an excellent fish to care for in their home aquarium.
