If viewed from above the females will look slightly larger and plumper.


To induce spawning, plenty of large water changes are required. A trio of one male and two females seems to work best placed in a shallow tank with a gravel substrate. When the eggs have been laid, remove the parents. The eggs should hatch after 2-3 days and when the fry are free swimming they can be fed on newly hatched brine shrimp.


The expected life span for Corydoras zygatus is 3-5 years.

Short description

Always keep Corydoras zygatus in small groups. They tend to be more active at night so will need some hiding places in the daylight hours.
