A wide range of feeding behaviors and diets are represented by the catfishes. In the family Trichomycteridae alone, there are species that feed on algae, fish scales, mucus, carrion, insects, or even blood in the infamous candirú. Panaque and some species of Hypostomus are unique among catfishes in that are the only fishes able to eat and digest wood.Members of the aspredinid genus Amaralia are known to specialize in feeding on loricariid eggs.
