It appears that a range of species from a number of different families eat sponges.  These include some species of angelfishes (Pomacanthidae), wrasses (Labridae), leatherjackets (Monacanthidae), boxfishes (Ostraciidae) and pufferfishes (Tetraodontidae) For some species, sponges comprise over 70% of the diet.
