Lori’s Anthias (Pseudanthias lori) – A Vibrant and Graceful Reef Fish
The Lori’s Anthias, also known as the Queen Tiger Anthias, is a stunning and relatively small anthias species known for its vibrant coloration and peaceful demeanor. Originating from the reefs of the East Indian Ocean, Australia, Indonesia, and the Central/West Pacific, this species is a popular choice for reef aquarists seeking a colorful and active addition to their tanks.
Appearance and Coloration
Lori’s Anthias exhibit distinct sexual dimorphism, with males and females displaying different color patterns:
• Males: Feature a vibrant pinkish to lavender-pink coloration with a series of bright red bars along the back, a reddish-orange streak on the upper part of the caudal peduncle, and small iridescent orange spots on the sides.
• Females: Display similar colors but are less vibrant, with a pale underbelly and a yellow snout. Their fins are more rounded compared to males.
This striking coloration makes Lori’s Anthias a visually appealing species in marine aquariums.
Natural Habitat and Behavior
In the wild, Lori’s Anthias are found in the reefs of the East Indian Ocean, Australia, Indonesia, and the Central/West Pacific, inhabiting:
• Deep reef slopes: Typically at depths ranging from 15 to 70 meters (50 to 230 feet), often near caves and crevices that provide quick hiding places.
• Social Structure: They form harems consisting of one dominant male and multiple females. If the dominant male perishes, the largest female will often morph to take its place.
In captivity, they thrive in well-structured aquariums with ample hiding spots and open swimming areas.
Tank Requirements and Water Parameters
To ensure the well-being of Lori’s Anthias in captivity:
• Minimum Tank Size: A 70-gallon (265 liters) tank is suitable for a single specimen. For groups, a 125-gallon (475 liters) or larger aquarium is recommended.
• Water Parameters:
• Temperature: 72°F – 78°F (22°C – 25.5°C)
• pH: 8.1 – 8.4
• Specific Gravity: 1.020 – 1.025
• Aquascaping: Provide ample live rock formations to create hiding spots and territories, while ensuring open swimming spaces.
• Lighting: Standard reef aquarium lighting is sufficient.
• Water Movement: Moderate to strong, simulating their natural reef environment.
Maintaining stable water conditions is crucial for their health.
Diet and Feeding
Lori’s Anthias have a high metabolism and require frequent feedings:
• Diet: Primarily carnivorous, feeding on zooplankton in the wild. In captivity, offer:
• Enriched frozen mysis shrimp
• Enriched frozen brine shrimp
• High-quality flake foods
• Live foods (e.g., copepods, amphipods) can be beneficial, especially during acclimation.
• Feeding Frequency: Due to their constant activity and high metabolisms, they should be fed small amounts several times per day (at least three times daily) to maintain good health.
An attached refugium cultivating copepods and amphipods provides a steady supply of nutritious live food, which can be beneficial for this active planktivore.
Compatibility and Social Structure
Lori’s Anthias are social fish that thrive in groups:
• Social Structure: Best kept in harems consisting of one male and multiple females. Avoid keeping multiple males in the same tank, as it can lead to aggression.
• Temperament: Generally peaceful but may be shy, especially when first introduced. They should not be housed with overly aggressive species.
• Compatible Tank Mates: Suitable companions include other peaceful reef fish, such as gobies, blennies, and small wrasses. Avoid housing with aggressive or overly competitive feeders.
Providing a peaceful environment with compatible tank mates will help reduce stress
