Corydoras aeneus

Corydoras aeneus
Corydoras aeneus – March 13, 2012

This is one of the more popular Corydoras varieties. In my experience, cories are most at home in tanks with a sand substrate. Searching for food, they will suck in the sand from their mouths and expunge it from their gills. Every now and then, they’ll rocket up to the water surface for a gulp of air. A fascinating fish to be sure.
