Discussion
The results of this study show that although upwards of 70% of fish
species may consume invertebrate prey (Kramer et al. 2015), no other
fish functional group has as high of a likelihood of consuming gnathiids
as dedicated cleaners. Further, both dedicated and facultative cleaners
consumed similar amounts of gnathiids, while all other functional groups
rarely consumed them, and when they did, consumed very few.
