Bicolor Pseudochromis (Pictichromis Paccagnellae), also known as Bicolor Dottybacks , Pseudochromis Paccagnellae, or just Royal Dottyback fish, are some of the most beautiful and diverse fish in the aquarium hobby, and popular saltwater fish due to their striking coloration and hardiness in captivity.

As its name implies, it has two different colors on its body. They have a slender elongated body with a bright yellow posterior and a purple anterior that leans toward a fuchsia color. Their color palette sometimes fades in captivity. This may be due to dietary deficiencies. They grow to a maximum length of 3” in the wild, although 2.5” is more common in captive environments.

A reef aquarium made of rocks and corals will be perfect for its maintenance. A 30 gallon or larger aquarium should be provided. They should be provided with plenty of hiding spots, which they will defend upon intrusion.

These gorgeous fish are considered to be  Semi-aggressive and should ideally be housed with similarly mannered tankmates. The Bicolor Dottyback will not be intimidated by other fish and will defend its territory against fish two to three times its size. It will fight to the death with conspecifics or other similar-looking species. They’re also not beyond nipping the fins of much larger tankmates. Generally reef safe, but will prey on small crustaceans. It will also eat ornamental shrimp and is a predator of nuisance bristleworms.

These fish are voracious carnivores. In captivity they can be fed vitamin enriched brine shrimp, mysis shrimp, and finely chopped fresh shrimp, krill, clams, mussels, crab, octopus, and squid. They will often eat pellets or granulated foods. They have also been known to nibble on marine fish food formulated for omnivores.
