Food and feeding
Many-spotted corys will accept all foods offered. Ensure that they get their share of the food; sometimes this may mean feeding them at dusk. A treat of blood worms or brine shrimp will be welcomed.
South America; Many-spotted corys are to be found in Paraguay and Brazil.
When viewed from above, the females will be slightly larger and stockier.
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.
Corydoras polystictus has quite a long life span, anything up to 10 years.
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.
