Pygmy Cory Catfish is a very peaceful schooling fish that is compatible with most nano aquarium animals. It might eat dwarf shrimp fry, but is generally safe to keep with adult dwarf shrimp. It is a classic scavenger and will inhabit and feed at the aquarium floor, which should be comprised of sand or smooth gravel. Very coarse substrate can damage its delicate barbels and underbelly. It is adaptable to most tropical freshwater conditions as long as standard regular maintenance is performed and sudden changes are avoided.
