What type of feeders are.....?

Question

Tangs, angelfish, dottybacks and clowns. I meen are they grazers and so on

Answer 1

Tangs are herbivores (eat plants, so I guess you could call them grazers - they'll graze on certain types of algae). Dottybacks are carnivores (eat animal-based foods - shrimp, pods, worms, so you could call these predators). Angels and clowns are omnivores (eat both plants and animals).
