Sexing In Dianema, Hoplosternum and Megalechis (but not in Callichthys), medial expansions of the coracoid bones are especially developed, covering most of the skin between the pectoral fins and sometimes overlapping in the midline in fully developed mature males (vs. not fully covering the abdominal skin and not overlapping in females). Mature males of Callichthys, Dianema, Hoplosternum, Lepthoplosternum, and Megalechis have a thick adipose body on the ventral surface of the pectoral fin. Mature females of Dianema, Hoplosternum and Megalechis have a small fold of skin on the external face of the leading pelvic-fin ray.

Rear fry in a tank with algae, feeding with Artemia and prepared babyfood (such as TetraMin Babyfood).
