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.
