Species choice and social planning
Anthias species differ in adult size, aggression, preferred depth, and willingness to adapt to aquarium life. Some form manageable groups in large systems, while others are better kept singly or require experienced care. Research the exact species rather than applying one schooling rule to all anthias.
When planning a group, consider sex ratio, aquarium dimensions, retreat areas, and the likelihood that social hierarchy will change. Have a plan to separate a bullied fish instead of waiting for weight loss or persistent hiding.
Frequent feeding and filtration
Anthias are active planktivores and often do best with several small meals spread through the day. Use quality pellets and varied frozen foods of suitable size, and confirm that shy individuals receive food rather than relying on one heavy feeding.
Frequent feeding increases nutrient input, so filtration and maintenance must match the routine. Remove uneaten food, monitor nitrate and phosphate trends, and balance nutrition with the aquarium’s export capacity.
Flow, shelter, and tankmates
Provide oxygen-rich water, useful current, open swimming areas, and shaded rockwork where subordinate fish can retreat. Avoid chaotic flow that prevents controlled feeding or traps a tired fish away from shelter.
Choose tankmates that do not monopolize food or harass anthias continuously. Quarantine new arrivals when possible, keep temperature and salinity stable, and watch appetite and body condition closely during acclimation.
