A must have species if you are a keen
Corydoras keeper. Females grow larger than the males.
Aquarium Care: Will do best in a small species
only tank or kept with small tankmates such as small tetras and
dwarf rasboras. C.pygmaeus is a bit like C.
hastatus in that it likes to shoal in
midwater and as such should be kept in a group of at least six.
Substrate can be of fine sand and plants such as java moss and
java fern can be used alongside rockwork for further effect. If
kept in a species tank for breeding, a fine substrate, java moss
and a sponge filter would suffice with weekly 50% water changes
to keep the water pure. Diet: Small foods such
as microworm, grindal worm, good quality flake and tablets. Frozen
foods such as bloodworm.
