This fish was originally mislabeled by aquarists as J. transcriptus (Kombe). However it is not transcriptus, and according to species descriptions may be marlieri... or something else.
Julidochromis are omnivores, primarily feeding on crustaceans, insect larvae and molluscs found in the aufwuchs. They also ingest sand particles as well as filementous and diatomaceous algae.
A diet in the aquarium could include mysis shrimp, mosquito larvae, daphnia, plankton as well as high quality flakes and pellets.
