Description
Mystery Wrasse (Pseudocheilinus ocellatus) is a spectacular and relatively uncommon marine wrasse known for its intricate coloration, distinctive eye-like markings, and vibrant combination of red, orange, pink, and white patterns. It is an active, secretive fish that spends much of its time exploring live rock, searching for small crustaceans, and retreating into caves and crevices. It is prized in marine aquariums for its unusual appearance and interesting behavior.
Lighting
Moderate to high
Normal reef lighting is suitable. Provide shaded areas and caves within the rockwork where the fish can retreat when resting or feeling threatened.
Placement (Aquarium Zone)
Middle to lower reef
Provide extensive live rock with caves, crevices, and overhangs. Maintain open swimming areas around the rockwork for natural hunting and exploration.
Temperature
Supplemental foods:
Mysis shrimp
Enriched brine shrimp
Copepods
Amphipods
Small marine crustaceans
Finely chopped seafood
High-quality small marine pellets
Frozen carnivore preparations
Feed small portions 1–2 times daily. A varied diet helps maintain body condition and natural coloration.
Adult Size (up to)
Approximately 10–12 cm (4–5 inches)
Growth Rate
Moderate
Care Level
Intermediate to Advanced
Generally reef-safe
Usually compatible with SPS corals, LPS corals, soft corals, and most ornamental invertebrates. However, it may consume small ornamental shrimp and other tiny crustaceans. Its natural diet includes copepods and amphipods.
Temperament
Semi-aggressive
Generally manageable with peaceful community fish but may become territorial toward other wrasses, particularly similar species and fish with comparable body shapes. Provide sufficient rockwork and hiding places to reduce territorial conflicts.
Special Requirements
Provide plenty of mature live rock with caves and hiding places.
Maintain a secure aquarium cover, as wrasses can jump.
Introduce carefully when keeping multiple wrasse species.
Provide a varied diet rich in small meaty marine foods.
Avoid housing with very small ornamental shrimp.
Allow sufficient swimming space and establish a stable social environment.
