Habitat & Tank Requirements

• Tank Environment: Provide dimmed lighting or shaded areas with extensive rockwork and caves. This deepwater species requires subdued conditions to thrive. Strong water flow is not necessary and may stress the fish.
• Water Parameters:
  • Temperature: 68-74°F (20-23°C) (cooler than typical reef tanks)
  • Salinity: 1.023-1.025
  • pH: 8.1-8.4
  • Pristine water quality is essential
• Equipment Recommendations:
  • Aquarium chiller (critical for maintaining proper temperature)
  • High-quality protein skimmer
  • Gentle water circulation These deepwater conditions are non-negotiable for long-term success.

Diet & Feeding

Blotched Borbonius Anthias are carnivorous and require frequent, protein-rich feedings. Recommended foods include:

• Staples: High-quality marine pellets (once acclimated)
• Frozen Foods: Mysis shrimp, enriched brine shrimp, finely chopped krill, cyclops
• Live Foods: Live brine shrimp, live mysis (often required initially)
• Feeding Frequency: 2-3 times daily minimum
• Special Note: May be slow to accept prepared foods; patience during acclimation is critical

Social Structure & Group Dynamics

• Can Be Kept Singly or in Groups: Unlike many anthias, this species tolerates solitary life well
• Sexual Dimorphism: Males typically show more intense coloration with deeper pink tones. Females are slightly smaller with paler mottling.
• Sequential Hermaphroditism: Capable of sex change from female to male
• Peaceful Nature: Non-aggressive toward conspecifics and other species

Notes & Considerations

• This is a challenging species requiring cooler water temperatures than standard reef aquariums.
• Collected from depths of 200+ feet, they are sensitive to bright lighting and should have access to shaded areas.
• Initially very shy; may hide extensively until fully acclimated.
• A secure lid is essential as all anthias are capable jumpers.
• Not recommended for mixed anthias tanks due to different temperature requirements.
• Limited availability and higher price point reflect collection difficulty.
