The Ellis Cory Catfish (Corydoras ellisae) is relatively new and is not commonly seen in the aquarium hobby. Only fairly recently have tank-bred specimens become available on a wider basis. It has mottled gray, silver, black, and emerald green markings and a slightly longer body than many other Corydoras species.
The Ellis Cory Catfish is a very peaceful schooling fish that is compatible with most nano aquarium animals, including dwarf cichlids and angelfish. It might prey on some smaller dwarf shrimp, but is safe with larger shrimp and most other peaceful ornamental invertebrates. 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, so it should be kept in an aquarium with sand or very smooth gravel substrate. This fish is otherwise undemanding as it will accept most dry, frozen, and live foods. It is adaptable to most tropical freshwater conditions as long as standard regular maintenance is performed and sudden changes are avoided. While it is a scavenger, care must be taken to ensure that it receives a good variety of high quality foods and is not simply expected to eat leftover food that other fish do not eat.
