I have kept Anthias for years. There is a definite pecking order. After quarantine I add the most timid species: evansi, tuka, flavoguttatus, ventralis, first; then carberryi, ignites,dispar, parvo, sunburst, and borbonious second -several days later; and days after : bimaculatus, bartlett, and lyretail last. Anthias do best in schools with a lot more females than males. They are carnivores with small mouths and like several feedings daily of small mysis,calamus, fish eggs, daphnia, and some will eat small flake food, freeze dried plankton, and pelleted food. They like oxygen rich water with good current. They appreciate low nitrate levels and I’ve enticed reticent Anthias with frozen daphnia and then mix with the daphnia small mysis and brine shrimp and other higher protein foods. Anthias can be more demanding to keep than some other fish but as long as you are proactive in meeting their needs , they can be kept for years.
