Hawaiian Black Triggerfish (Melichthys niger) is an omnivore that can be fed a mixed diet of shrimp, squid, clams, fish, and other meaty fares suitable for carnivores, as well as marine algae and vitamin-enriched herbivore foods.

What do you feed triggerfish?

Triggerfish mostly require a carnivorous diet, so you'll need to make sure you feed them a variety of meaty foods. Mysis shrimp, prawn, shell-on shrimp, clams, fish, high-protein fish pellets, and squid are particularly good options.

Do triggerfish eat fish?

You may also see triggerfish eating other smaller fish. They do not hunt fish, but will opportunistically eat the flesh of dead fish.
