Pygmy Cory Catfish: Species Overview

The Pygmy Cory is a popular choice for saltwater aquariums due to its small size and active nature. They can be kept in small spaces and often get along well with other species. In addition, they are very active right from the start, so they make great additions to any saltwater tank.

Typical Behavior

The Pygmy Cory is an active fish that loves to swim and explore. They will often get along well with other species in a saltwater aquarium but may be territorial if kept alone for a very long time. In addition, they are small enough that they won’t be a problem when other tank mates bump into them. In addition, these pygmy cats are known for their playful, curious nature and will often be found searching around the aquarium as they explore. As long as these fish get plenty of food and are adequately cared for, they will stay healthy. If given a large amount of food and enough space to swim around, these fish may grow quite large in a tank without any issues with their health or growth.


The Pygmy Cory is a small fish that can range in color from yellow to light green. They have a torpedo-like shape and often have darker markings on their heads and bodies. In addition, they have a long dorsal and anal fin that makes them appear flat. Their size can be affected by their health and whether or not they get enough food during captivity. Thanks to their small appetite, they will grow larger if given more space than what’s needed for a small fish and don’t receive too much food.


The lifespan of these fish is usually around three years. However, it can be affected by their health and the size and condition of the tank in which they live. If kept at home for an extended period without natural behavior due to boredom, your pets could quickly die or suffer serious illness over time because they will receive no attention from you while inside their small cages or tanks. In addition, if given too many essential foods such as pellets, they can become obese and may suffer from obesity-related health issues inside the pet store.
