Top Cory Catfish for Aquariums

I have always been fascinated by Cory catfish, like these here. There are over 140 species and some haven’t been documented yet. These catfish genus come in countless blends of colors and are highly valued as pets. They are usually imported from the tropical waters of South America. However, you can find Corys that are farmed locally.

Before looking into the popular Cory species for aquariums, I’d like to state the criteria used in creating this list. Firstly, the size of the Cory plays a huge role. Most of the popular species are mid sized. Catching these doesn’t require catfish bait since they average between 5 and 6 centimeters, but you can find more about their baits at The second is availability. Many people prefer Corys that are easily available since they are less expensive. There are however Cory lovers who wouldn’t mind paying extra for an imported species. The third criteria is the Corys breeding and reproductive habits. Fish that are easy to breed are most preferred. Finally, color blends also play a huge role. Most people love Corys that have striking colors and patterns. Now here’s the top list.

Julii Cory

Although quite popular, this Cory isn’t an easy find in most pet shops. Many buyers actually take home the Trilineatus Cory instead of the Julii. This Cory is indigenous to the lower Amazon and has a distinct gray body covered with black spots. This similarity with the Trilineatus is what confuses many. The main difference between these two Corys is that the Julii has distinct dark spots on the head. The Trilineatus on the other hand does have spots but they tend to join up into linear patterns on the head.

This fish prefers living in schools and a group of more than three is preferable. In the aquarium, it cohabits easily with small catfish, Cichlids and Danios. They are bottom feeders and will eat any sinking fish food. It’s recommended to have a separate breeding tank as these Corys can eat their eggs given the opportunity.

Bronze Cory

This Cory also comes in color variations of green, black and albino. It’s native to Argentina, Columbia and Peru. Owners particularly love them for their color variations and active nature. Being omnivorous, they will feed on almost anything presented to them. Like other Corys, they like to live in schools and a group of six or more will do. Peaceful smaller fish make great companions in the aquarium.

Skunk Cory

This Cory is native to Brazil, Peru, Ecuador and Columbia. As the name suggests, this Cory has distinct black stripes that run from the mouth, across the eyes to the back. Its body is usually creamy-white. Some individuals can also spot a gold tone. One of their unique features is their ability to draw oxygen directly from air. For most owners, this is a sign that the aquarium is oxygen deprived. A school of six or more mixed with peaceful small fish usually works in an aquarium. After spawning, it’s recommended to separate parents from the spawns as they can eat up the eggs and frys.
