Ecology Summary - Perissodus microlepis

Language:

Main Ref.	Konings, A., 1988
Remarks	Is a specialized scale-eater but is still euryphagous, like most lepidophagous fishes. Juveniles feed on a wide variety of food items but the adults feed mainly on fish scales. The majority of adults; however, also take other food at the same time. Parents guarding their young seem to depend more on zooplankters than are solitary adults, owing to the limitation of their movements (Ref. 42327). Generally, this species prefers fish that feed from the algal layer or fish which are inattentive, the usual prey being Tropheus and Pseudosimochromis (Ref. 7343).
