The Similis Corydoras Catfish, otherwise known as the Smudge Spot Cory inhabits the Rio Madeira Basin in Brazil. The Similis Corydoras Catfish lives in small tributaries, creeks, pools and areas of flooded forest in the wild.
An aquarium of 20 gallons or more should be provided to accommodate a minimum group of 3 to 4 Similis Corydoras. An aquarium set up to replicate an Amazon biotope will be appreciated. Use a soft, sandy substrate with a few dried leaves such as Beech or Oak to naturally soften the water as their tannins are released. Aquascape the aquarium with smooth edged rocks and driftwood while leaving open spaces and areas for the catfish to swim.
Similis Corydoras Catfish are foraging omnivores and that require a well balanced diet including quality flake food and pellets along with frozen/thawed blood worms, brine shrimp and mysis shrimp for adult specimens.
