Food and feeding

Origin

South America; Many-spotted corys are to be found in Paraguay and Brazil.

Sexing

When viewed from above, the females will be slightly larger and stockier.

Breeding

Once the fish have spawned the female will collect the eggs and sperm ion the usual “T” position that she adopts with her pelvic fins. The eggs will be placed on plants and the tank glass; they should hatch 3-5 days later. When the fry are free swimming, they can be fed on newly hatched brine shrimp or Infusoria. As they grow, crushed flake can also be offered.

Lifespan

Corydoras polystictus has quite a long life span, anything up to 10 years.

Short description

An excellent candidate for a community tank, Many-spotted corys should be kept in groups of at least 5 fish, avoid boisterous tank mates, as these are a peaceful species.
