Green Cory Catfish
The Green Cory catfish is one of the most popular Corydoras catfish species. They show their best behavior while shoaling in groups of 2 or more fish. The Green Cory is extremely peaceful making it a great addition to any community tank and even most shrimp tanks. Green Corydoras reach a max size of around 2.5 inches.
Corydoras species prefer a sand substrate as they enjoy scavenging for food. It is also less abrasive to their barbels making sand the best long-term substrate solution for the Corydoras family.

I added a group of three Green Corys to my 10-gallon tank with shrimp. They are very calm and don’t bother the shrimp. They enjoy the sand substrate and eat a variety of foods. Easy to care for and a great addition to a community tank.

The fish are peaceful and active. I feed them a mix of flakes and frozen foods daily. They seem to thrive in a sand-bottom tank and don’t dig up the substrate much.

I’ve had Green Corys for six months now. They’re very social and always swim together. The barbels are healthy and they eat well with a varied diet. Perfect for a beginner aquarist.
