Food and feeding
Due to their size, Dwarf corydoras need the smaller quality flakes and sinking pellets. They will readily accept all types of worms, broken up algae wafers should also be included in their diet.
South America; Dwarf corydoras are to be found in the rivers and tributaries.
When viewed from above the females will be larger and more rounded in body shape.
Corydoras pygmaeus, once they are spawning, will scatter their eggs around the plants and tank glass. The eggs tend to be placed separately, rather than in groups. The eggs should hatch in 3-5 days, but the fry will be very small. Feed them on newly hatched brine shrimp and as they grow they can be fed on finely crushed flake.
The expected life span is 3-5 years.
Dwarf corydoras need to be kept in groups of at least 6 fish. They are very peaceful and do well in any community tank.
