Common name: Lyretail dottyback

General information

The Diadem Dottyback, scientifically known as Pseudochromis moorei, is a small and vibrantly colored marine fish that is popular among reef aquarium enthusiasts. This species is part of the Pseudochromidae family, known for their bold personalities and striking colors. The Diadem Dottyback has a deep purple to violet body with a black stripe running from the eye to the base of the tail, which can make it a standout addition to any reef tank.

Care

Diadem Dottybacks are relatively hardy and can be a good choice for both beginner and advanced aquarists. They thrive in well-established aquariums with plenty of rockwork and hiding spaces. These fish are known to be territorial, so it's important to provide them with an environment where they can establish their own territory without encroaching on the space of other tank inhabitants. They are carnivorous and should be fed a varied diet of meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood.

Reproduction

In the aquarium, Diadem Dottybacks can be bred with careful attention to their environment and conditions. They are protogynous hermaphrodites, meaning they are born female and have the ability to turn male if no other males are present. Breeding pairs will lay eggs in a secure crevice, and the male typically guards the eggs until they hatch.

Habitat

Pseudochromis moorei is native to the Western Pacific, particularly around the Great Barrier Reef and Coral Sea. They are typically found in reef environments, often associating with stony and soft corals at depths ranging from shallow waters to about 40 meters.

Given their natural habitat, replicating similar conditions with a combination of live rock and coral can provide a comfortable and naturalistic setting for these fish in captivity.
