Pseudochromis

Pseudochromis olivaceus

Ruppell, 1835

Olive Dottyback

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Western Indian Ocean: Red Sea.

Size: 4 inches (9 cm)

Natural Environment: Inhabits caves and crevices in rocky reefs and is usually found between depths of 3 to 65 feet (1 – 20 m) where it feeds on smaller fishes and crustaceans.

General Husbandry: Rarely seen in the trade having an olive-black body with a black spot on the gill plate, and a yellow tail.

Can be maintained in reef or fish-only aquariums having some rocky hiding places/crevices to take shelter, as this species is secretive, especially upon first entering the aquarium. However, it will become bolder and quite aggressive to smaller tankmates, and will also dig under rocks and corals or hide in branches of corals. Tankmates should be larger and at least moderately aggressive.

As to diet, products such as marine fish and crustacean flesh, clams, and other marine meaty foods should make up the majority of their diet. Therefore a meaty diet such as enriched chopped fresh fish or shrimp flesh, and/or frozen carnivore foods should be fed once daily.

Taxonomy:

    Order: Perciformes

    Suborder: Percoidei

    Family: Pseudochromidae

    Subfamily: Pseudochrominae

    Genus: Pseudochromis

FYI: Since they are extremely fast moving and secretive, if having to remove it from a reef aquarium with many hiding areas, it would be a major task!
