Description
Mystery Wrasse (Pseudocheilinus ocellatus) is a striking, secretive reef fish known for its intense red, pink, orange, and white coloration. It is an active swimmer that spends much of its time around rockwork and can be an excellent addition to an established reef aquarium. It may become territorial toward other wrasses or similarly shaped fish, so careful tank-mate selection is important.
Lighting
Moderate to high
Normal reef lighting is suitable. Provide shaded areas and caves within the rockwork where the fish can retreat.
Placement (Aquarium Zone)
Middle reef
Provide extensive live rock with caves, crevices, and overhangs for shelter and exploration.
Temperature
24–27°C (75–81°F)
Salinity
1.025–1.026 SG
pH
8.1–8.4
Alkalinity
7–9 dKH
Consistency is more important than maintaining a specific value.
Calcium
420–450 ppm
Magnesium
1280–1380 ppm
Flow
Moderate to strong, turbulent flow
Provide good circulation throughout the aquarium while maintaining calmer areas around caves and rockwork.
Diet
Carnivorous + Frequent Feeding
A varied diet of small meaty marine foods is recommended.
Supplemental foods:
Mysis shrimp
Brine shrimp
Copepods
Small marine crustaceans
Finely chopped seafood
High-quality marine pellets
Frozen carnivore preparations
Feed small portions 1–2 times daily, with additional feeding helpful in established reef systems.
Adult Size (up to)
Approximately 10 cm (4 inches)
Growth Rate
Moderate
Care Level
Intermediate
Reef Compatibility
Reef-safe
Generally compatible with corals and most reef invertebrates, although individual behavior can vary. It may prey on very small ornamental crustaceans and can compete with other wrasses for territory.
