Younger hardhead catfish tend to eat small crustaceans, like amphipods, shrimp, blue crabs, mollusks, and annelids. [10] Juveniles that are still under the protection of the male mouthbrooder feed predominately on planktonic crustaceans close by to the mouth of the parent. [8] The adults primarily consume larger fish. [10]
Callichthyids are fairly small catfish, and range in size from some tiny Corydoras species that do not exceed 2 cm (0.79 in) to Hoplosternum littorale, which some sources list as growing to a length of up to 24 cm (9.4 in) TL. [3] [14] The mouth is small and ventral with one or two pairs of well-developed barbels. [4]
Upon hatching, the young forage for plankton in short bursts but will quickly return to the safety of the mouth of the adult if alarmed. They eventually become independent once they reach a size of 30 to 44 mm (1.2 to 1.7 in). During the entire period, the adults do not eat and their stomachs shrink dramatically. [9]
