Diet & Feeding

Dispar Anthias are planktivores requiring regular feeding. Recommended foods include:

• Frozen Foods: Mysis shrimp, brine shrimp, cyclops, copepods, finely chopped krill
• Live Foods: Enriched brine shrimp, copepods (helpful during acclimation)
• Feeding Frequency: 2-3 times daily minimum
• Special Note: Generally easier to train onto prepared foods than more delicate anthias species

Social Structure & Group Dynamics

• Best Kept in Groups: Ideal ratio is 1 male to 3-5 females
• Sexual Dimorphism: Males display vibrant red-orange coloration with pink highlights and a distinctive red spot on the pectoral fin base. Females are peachy-orange with softer tones.
