The Achilles tang is herbivorous, eating mostly benthic algae. They will also accept frozen and meaty foods such as brine shrimp and mysis shrimp in captivity. As with all surgeonfish, algae or similar vegetable matter should be included in their dietary intake to moderate aggression and regulate metabolic functions.References:
