What do sarcastic fringehead fish eat?

Sarcastic fringehead fish, despite their intimidating appearance, are actually carnivores with a diet consisting primarily of:

* Small fish: They are opportunistic feeders and will snatch up any fish that fit in their mouths, including gobies, shrimp, and other small fish that are readily available in their rocky reef habitats.

* Crustaceans: They also enjoy eating crabs, shrimp, and other crustaceans they can catch.

* Worms: They are not averse to eating worms, which they find in the crevices and cracks of their rocky homes.

They are known to be quite aggressive when it comes to feeding, with males often exhibiting territorial behavior and fiercely defending their food sources.
