This genus was previously placed
in its own family of Ageneiosidae and you can still
find some publications that still follow this line.
Habitat: Ageneiosus militaris lives
in rivers, eating fish and microcrustaceans. In the
Paraná River one finds it in spring, summer
and early fall. Reproduction: They
do not have parental care and fertilization is internal.
In the breeding season males have ossified chins,
modifications in the spine of the dorsal fin and previous
anal fin rays form the gonopodium. (Da Graça
and) Pavanelli, 2007).
