Care

Midnight Dottybacks are suitable for both novice and experienced aquarists. They thrive in well-established aquariums with plenty of rockwork and hiding spaces. These fish are carnivorous and require a diet consisting of meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood. They can be territorial, so it's important to introduce them to the aquarium last to minimize aggression towards other tank mates.

Reproduction

In the wild, Midnight Dottybacks are secretive spawners, laying their eggs in hidden crevices. In captivity, breeding can be challenging, but with a well-structured environment and a pair of mature fish, hobbyists may observe spawning behavior. The male typically guards the eggs until they hatch.

Habitat

Manonichthys paranox is found in the Western Pacific, particularly around Indonesia and the Philippines. They inhabit coral reefs and are often associated with crevices and overhangs where they can seek refuge. In the aquarium, replicating this environment with ample rockwork can help these fish feel secure and display natural behaviors.
