Habitat: Occurs
over mud in streams and lakes and forms schools. Diet:
Omnivorous, feeding mainly on insects, crustaceans,
mollusks, other invertebrates and some vegetable material.
Aquarium Care: Quite a character
obviously suited to large accommodation especially
if keeping a number of fish together. Peaceful towards
other fish and members of its own kind with doradids
such as Agamyxis
pectinifrons (Spotted
Dora), Platydoras
armatulus (Striped Dora), Oscars and any
other fish of a compatible size. Large pieces of bogwood
and clean plastic drainpipe of suitable diameter for
them to hide under. Ideally heater guards should be
provided in order for the fish not to burn themselves.

Rudolf Kner, the Austrian ichthyoligist.
