What critical vegetable or Spirulina content must manufactured flake and pellet foods possess for herbivorous tangs?
Answer
A high vegetable or Spirulina content
Flake and pellet foods are acceptable supplements for the Yellow Tang diet, provided they are selected carefully to complement the marine algae staple. Because the fish requires consistent vegetable intake, these manufactured products must contain a significant proportion of vegetable matter or Spirulina. They should not be treated as general fish food. Hobbyists should specifically seek out high-quality sinking pellets that are engineered or formulated with the needs of herbivorous tangs and surgeonfish in mind, ensuring that any supplemental feeding still aligns with the fundamental plant-based requirement.
