Food and feeding

San juan cories will accept all foods, quality flake, sinking pellets, and algae wafers. They have a definite liking to shrimp pellets and will accept meaty foods as well, even chopped earthworms.

Origin

South America; San juan cories originate from the Madeira River basin in Bolivia.

Sexing

Females are bigger and stockier; males tend to be a lot slimmer in their profile.

Breeding

San juan cories are very hard to breed. There are reported cases however so there is some limited information. The breeding pair must be conditioned on high protein foods for at least 2 weeks. Doing a cooler water change should then induce them to spawn. The eggs should hatch after 3-4 days and when the fry are free swimming, very small foods should be offered as they are tiny. Either feed them on a commercial fry food or Infusoria.

Lifespan

Expected life span for San juan cory is 3-8 years.

Short description

This Cory prefers a planted tank containing plants and driftwood; Corydoras bilineatus should be kept in groups of at least 5 fish.
